The Zenith El Primero A385 is a very distinctive watch. While the two other watches in the trilogy were a bit more classic in their design, the A385 was bold. Based on the same case as the A384, meaning a 37mm cushion-shaped block of steel, it stood out thanks to its dial, with a warm colour and, something new for the industry, a dégradé smoked effect – according to Zenith, this was “the first smoked dial ever to be made in the watch industry” (something that would need to be verified…)roger dubuis tourbillon Replica Mechanically, there was no difference between the watches from the trilogy, as all were using the same El Primero movement. Something to be noted about the A385; in 1970, it took part in Zenith’s “Operation Sky.” This extreme test consisted of strapping the watch to an Air France Boeing 707’s landing gear on a flight from Paris to New York to test its resistance to external aggressions such as drastic temperature fluctuations, wind force and roger dubuis lamborghini Replica changing air pressure. Upon landing, the watch was still functioning perfectly. There’s no denying the actual beauty of the watches from the 1969 El Primero trilogy. All of them, with their own distinctive design, can be named “emblematic” – with a special mention for the A386, which has gained an indisputable cult status in auction rooms. Nevertheless, the A384 and A385 models are equally attractive and, possibly, even more representative of the era when the El Primero movement was launched. With the exception of its tri-colour dial, the A386 remains a rather classic watch while the two others, and even more the A385, are watches with true late-1960s styling. Credits where credit’s due; Zenith should be applauded for the faithfulness of their Revival watches. Certainly, one could note a certain lack of imagination in the idea of recreating a past model, however, as the trend for vintage-inspired watches doesn’t tend to slow down, at least when Zenith does it, it does it right. In short, the Chronomaster Revival A385 is, just like the Chronomaster Revival A384, an almost 1-to-1 reproduction of the original model – except for some minor details. Many (countless) brands have embarked on the vintage train but few can claim to still produce the same movement as the inspiration watch… And that changes everything, specifically when it comes to dimensions of the case and dial layout. panerai luminor marina replica So, let’s get straight to the point, the Revival A385 is extremely loyal to its predecessor, in almost every single aspect. Starting with the case, not only the style has been reproduced but also the proportions. Compact in terms of diameter, at only 37mm like the original, it remains a watch with a relatively modern presence, with a 47mm lug-to-lug measurement. The height is also moderate for an automatic chronograph, at 12.6mm – the El Primero is fairly thin compared to its modern counterparts with vertical clutch. iwc portuguese replica The shape, since Zenith scanned an old model, is fully identical and retains the sharp angles found on the 1969 cushion-shaped case. The top surface is radially-brushed, which participates in the retro look of the watch, the sides are horizontally brushed, and on the side is a polished bevel that brings dynamism. The main specificity of the case of the A384 and A385 was the angled surface of the lugs, which are still present and polished like the original model. The right side is home for historically-accurate pushers and crown and the main update is the material used for the crystal, where modern sapphire replaces Plexiglas. Other than that, this Chronomaster Revival A385 is basically identical to an unworn 1969 model that would have been kept in a safe… yet with more precise execution. But that’s not new, since the Revival A384 uses the same case. What changes here is the dial… a funky, bold, colourful, warm dial with outdated coolness. While the A384 played on sporty cues, with a classic panda dial highlighted by a touch of red, this A385 sports a brown smoked dial – with a strong degradé effect ranging from almost black in the periphery to a very light brown-beige in the centre. Framed by a ubiquitous tachymeter scale, it reproduces once again faithfully the design of the original model, down to the facetted and rhodium-plated hour markers and hands, the red central seconds hand, or the inscriptions with historic fonts and logo. The sub-dials, with small seconds, 30-minute and 12-hour counters, are white and so is the date window at 3 o’clock – which gives here visual consistency. The indications are filled with cream-coloured Super-LumiNova, which works well with the rest of the dial’s tones. While also available on a light brown leather strap, it makes sense to go for the steel bracelet on this watch… Because, here also, Zenith has played on visual accuracy and has reproduced a style that was used on the A384 and A385 models, the so-called ladder steel bracelet with hollowed links, once manufactured by Gay Frères. Light and flexible, it looks and feels right in place in this context. https://www.bestbuycheap.ru

Under the screwed sapphire caseback – the other noticeable update compared to the historical watch – is a well-known movement, and in fact a movement that is, like the rest of the watch, almost a 1-to-1 reproduction of what once powered the A385; you name it, the El Primero calibre. With a development that started in 1962 with the idea to launch it in 1965 for the manufacture’s centenary, it finally made its entry in 1969. However, after an estimated production of 32,000 movement units, Zenith Radio Corporation (a US company owning the brand since 1971) lost confidence in mechanical watches and, betting on quartz, decided to stop the production of the El Primero, and wanted to get rid of the tooling… but thanks to Charles Vermot, the watchmaker in charge of manufacturing, tools and manufacturing plans were saved, hidden in the manufacture’s attic. And in the early 1980s, Zenith was able to resume the production of its automatic chronograph. The Calibre El Primero 400 that powers the Chronomaster Revival A385 is the closest you can get from the original 1969 movement. If some upgrades have been implemented (better chronometry, more reliable parts where needed, better decoration and modern manufacturing techniques), it basically retains the same architecture and, a signature element, the 5Hz frequency. It is here presented with a star-shaped openwork rotor and pleasant finishing.

In 1957 the world was greeted by the arrival of Omega’s famous trilogy: Speedmaster, Railmaster and importantly the Seamaster 300. The Seamaster 300 was guaranteed to 200m although tests equivalent to 300m have been carried out without water ingress, hence the rear of the watch carried the title ‘certified high pressure waterproof Seamaster’.https://www.bestbuycheap.ru

The Omega Seamaster Diver 300M, in one form or another, has been around since 1993. But of all the various iterations over the decades, the most recent example with a polished ceramic dial, ceramic bezel, and Co-Axial caliber 8800 may be the one that’s finally found its footing. iwc portugieser chronograph replica

It’s a watch that feels like it took 26 years to get right. Past designs teetered back and forth between a luxury watch and a tool watch over the years, and it was an absolute commercial success, but it never had a unanimous vote from the enthusiast community. If it weren’t for the on-screen endorsement by Pierce Brosnan – the suavest Bond of them all – would the watch have hung around in Omega’s lineup for as long as it did? Since its inception, the design has had an equal number of fans and detractors. iwc big pilot replica The skeleton hands, helium escape valve at 10 o’clock, and scalloped bezel have forced a “love-it-or-hate-it” approach.

It’s a good thing the design did stick around as long as it has. The advent of modern material science in conjunction with the advancements in co-axial escapement and anti-magnetism technology have made this model – released in 2019 – the best it’s ever been. The fundamental design elements that make the watch polarizing are still there, but even the folks who bemoan them would be hard-pressed to disagree that there’s a ton of value in this execution. We’re used to seeing it in the iconic blue hue, but I think it’s the high-contrast white-dialed version that’s re-igniting the excitement over the Omeag Seamaster Diver 300M.

I’ve owned a “Bond Seamaster” for 14 years now, so I’ve had plenty of time to get acquainted with the idiosyncrasies of the overall design. But when I spent a week with the new white-dialed 2019 release, it actually didn’t feel familiar at all. It felt like I had to start back at square one with the watch. The changes Omega’s made have truly transformed the watch and forced me to see it in an entirely new light. It was like coming home to the house you grew up in after years away and discovering that you no longer know where everything is. I kept glancing at three o’clock for date. Nope. It’s at six o’clock now, just like the spatula that’s no longer in the kitchen drawer you thought it was in. The fonts have changed, like the layout of your childhood bedroom. It’s a guest room now. It’s all vaguely familiar, but it takes some serious getting used to. There’s a natural tendency to immediately reject change, but when it comes to this iteration of the Seamaster Diver 300M, I think the old adage “change is a good thing,” certainly holds true. jaeger lecoultre master replica

In the beginning, there was indeed a variant of the Seamaster Professional 300M with a white dial, but it wasn’t nearly as pretty as its smooth blue sibling, ref. 2541.80. The white-dialed Seamaster, ref. 2542.20.00, couldn’t be the darling of the collection even if it wanted to be. Like most things in life, it’s hard to get it right on the first try. So how did the Seamaster Professional 300M become an icon? vacheron constantin skeleton replica

The moment in the spotlight came two years after its release, when it appeared in the 1995 hit James Bond film, Goldeneye. According to Jason Heaton’s 2014 look at the Omega Seamaster 300 Master Co-Axial (it’s an entirely different watch, and the nomenclature is confusing, but decoding the myriad of executions and references and special editions is part of Omega’s charm), “costume designer Lindy Hemming chose an Omega Seamaster, then the blue-dialed version with the skeletonized sword hands. Hemming chose the Seamaster over other options largely based on the brand’s history with the British Navy, to which Bond had belonged. According to Hemming, ‘I had known contemporaries when I was in my twenties who were military and naval […] who all swore by their Omegas.'” tudor black bay bronze replica

It matched Pierce Brosnan’s Bond perfectly, in the sense that it was pretty enough to consistently charm us, and only tough when it needed to be. The case came polished and brushed in a way that made it less tool-like and more flashy to match Bond’s businessman-like looks and diplomatic demeanor. The bracelet on both references that Bond wore – a quartz (2541.80.00) and an automatic (2531.80.00) – featured two rows of links that were also highly polished and incredibly comfortable. As the watch became part of the Bond identity, sales soared.

The blue Omega Seamaster Professional 300M became an instant classic because of Bond. And in true Omega fashion, its popularity spawned dozens of iterations in different metals, dial colors, and complications. The 1990s and 2000s saw more than a handful of models emerge from the simple design that Bond popularized: There was a chronograph in titanium, a GMT with sword hands on a Speedmaster bracelet, a Japan-only midsize model with a red dial, a solid-gold version with a dark navy dial, a version in solid white gold produced for America’s Cup, a version designed for freediving dubbed the “Apnea,” a handful of 007 editions, a version in stainless and gold, another in titanium and rose gold. There are many more.

We could go further down the hole of Seamaster Professional 300M Divers, but I think we have to narrow the scope to the sub-set of white dials in the Seamaster Professional 300M and Seamaster Diver 300M family to compare apples to apples. What I found is that not only is this version the most attractive white-dialed model Omega has ever produced in the range, but to me, it even eclipses the iconic blue-dialed models in terms of beauty. There’s something about the monochromatic theme that comes to life in this iteration in a way that no other model has captured.

To fully appreciate the balance of this current design, let’s take a look at earlier white dial executions in the Omega Seamaster Diver and Professional 300M family.

To celebrate the 25th anniversary of the Seamaster, Omega released no less than 14 brand new Seamasters in 2019. That caught our collective attention, but it was the white dial variant that stole the show. It’s important to note that the 2019 releases are not a limited edition of any sort. They’re standard production models. This means that theoretically, it’s possible to walk into any Omega boutique or AD, plop down $4,900, and walk out with the pictured watch. There are three decades of experimentation in the current design, and at least one design detail from every iteration of white Seamaster 300M has made it into the newest version in one way or another. There is an argument to be made that the basic design has generally remained unchanged, however. And even though the watch feels much different, visually speaking, it’s true. There’s a certain continuity that’s present throughout the line, except that design changes are a bit more distinct, as opposed to the small permutations of the Rolex Submariner that are only visible to the highly trained eye.

Omega updated its Seamaster 300 collection and added a bronze gold version (reference 234.92.41.21.10.001) as well. Bronze certainly isn’t new to the industry. Nor is gold new to the Seamaster 300. However, this fresh new alloy — the aptly-named bronze gold — is something new to us all.

The Omega Seamaster 300 collection receives a few subtle changes, including an upgraded movement (caliber 8912, Master Chronometer certified) and modified case proportions. The 41mm diameter remains, but the case band and bezel combined are slimmer than before, with the old height retained by virtue of a boxy sapphire. The classic Broad Arrow hands and straight lugs remain. Without further ado, let’s have a look at the new bronze gold Seamaster 300 and see how it wears.

Omega Seamaster 300 Bronze Gold

Omega sent us a box of watches under embargo, and inside we found three new Seamaster 300 models. The bronze-gold Seamaster 300 234.92.41.21.10.001 is the one that received the most attention in our office. This new alloy has a number of characteristics that make it an interesting choice for a watch. First, there’s no risk for people with an allergy. Bronze watches often have a steel or titanium case back, so there’s no skin irritation. With bronze gold, there’s nothing to worry about.The bronze-gold alloy consists of copper, 9-karat gold, silver, gallium, and palladium. Omega doesn’t want to reveal the exact percentages of each material, but let us know that the color of this alloy sits between Moonshine (yellow) gold and Sedna (rose) gold. The use of palladium keeps the color bright and will reduce the patina effect. The Au375 engraving at least let us know there’s 37.5% gold in this alloy.

As you can see in the pictures, the Omega Seamaster 300 bronze gold uses a sandwich dial. There’s a German silver base plate, and a cover plate in bronze (92% copper). The German silver base plate is etched with the markings and filled with lume. The upper dial is then blackened, before being delicately brushed to reveal some of the warmer brown tones of the underlying substrate. This resulting “tropic” effect means that every dial will be unique due to this aging process of the bronze. The open 6 and 9 numerals were used in some of the earlier Seamaster 300 types from 1962.There’s no “Automatic” or “Master Chronometer” wording on the dial. Less is more, and this watch is a great example of how it should be done. Unlike the steel versions of the new Seamaster 300, this watch does not come with a lollipop second’s hand. Omega used the lollipop for their Seamaster 300 in 1959, but this is not an exact re-make of those watches, of course. It is inspired by various vintage Seamaster 300 watches.

The diving scale bezels on the very first Seamaster 300 from 1957, reference CK2913, were bi-directional with an unusual security system to prevent them from being accidentally turned. As you know, divers needed safety, and knowing the exact time they have left underwater is crucial. On the original Seamaster 300 bezels, one had to push the bezel down to unlock it before one could rotate it in either direction. This was later updated to the unidirectional method, which this bezel uses — another slight update to the older models. In contrast to the new steel models, this bezel has a brown ceramic insert.

Omega’s in-house developed caliber 8912 is inside the Seamaster 300 Bronze Gold watch. Based on the 8900 — as it can be found inside the Constellation Globemaster for example — the 8912 lacks a date function. Caliber 8912 has a power reserve of 60 hours, and an unusual operating frequency of 25,200vph. It goes without saying that the Seamaster 300 Bronze Gold has the Master Chronometer certification by Metas. Therefore, it is anti-magnetic to at least 15,000 gauss and has a daily average performance of 0/+5 seconds. If you want to know more about the Master Chronometer certification process.

Seamaster 300 Bronze Gold Replica on the wrist

As always, the proof is in the pudding. When I strapped on the new Omega Seamaster 300 Bronze Gold and the new steel models, I thought the watch appeared to be bigger than its predecessor. But that is not the case. The diameter of the Seamaster 300 is still 41mm. What changed is the aperture of the dial. It increased by 1mm. Omega made the case part and bezel a tad smaller, making it possible to increase the dial size. The height of the watch is 14.4mm, and the lug-to-lug is 48mm. The Seamaster 300 Bronze Gold comes with a calf leather strap, reminding me of the Speedmaster Speedy Tuesday strap. The lug-width is 21mm and the strap tapers to a 16mm (bronze gold) buckle.The dial on the Seamaster 300 Bronze Gold is superb in sunlight, giving it this “tropic” look. The creamy color of the Super-LumiNova really matches perfectly with the bronze-gold case material and the numerals on the diving bezel. I’ve worn the watch for a few days in a row, and it is an easy wearer. It looks great and it wears comfortably on my 19cm wrist. I am a Speedmaster guy, but I can definitely see myself wearing a Seamaster 300 as well.The bronze gold is in between the Moonshine and Sedna gold alloys, so it is slightly darker than yellow gold but not as red as rose (or pink) gold. Compared to my Oris Big Crown Pointer Date in bronze, it is clearly visible we’re talking about a different composition of materials here. It’s less coppery and more yellow. While there Oris started developing patina after a day, the Seamaster 300 Bronze Gold still looks like new after a weekend of wearing.

First thoughts on the Replica Seamaster 300 Bronze Gold

The bronze-gold alloy that Omega has patent-pending solves the problem of toxic bronze. Wearing a bronze watch directly on the skin may result in skin irritation and this new Seamaster 300 bronze gold can be worn without any issues. The use of noble materials like palladium, a significant amount of gold, and silver make this watch more expensive than a “regular” bronze watch, but in the end, it isn’t a bronze watch as we’ve come to expect from some other brands. Omega made an effort to keep the Seamaster 300 watch looking good at all times, and by using at least 37.5% gold in the alloy, the price is between the steel variation and a full gold watch.
