Omega continues to deliver a fascinating reinterpretation of the first authentic diving watch from 1957, but has also incorporated some unexpected changes, especially when compared to its predecessor from 2014. WatchTime takes a closer look at the new Seamaster 300 Co-Axial Master Chronometer.
Design
For our testing, Omega supplied a stainless steel model with a blue dial and matching diving bezel insert (Ref. 234.30.41.21.03.001) – a rather attractive combination that has previously been only available in platinum, bi-tone or titanium, with the latter costing about a third more than the stainless steel version with black dial. Given the classic appeal of this model (and the blue dial’s continued popularity), we’re glad this option is now available in stainless steel and feel it makes more sense to go without the hands. high-tech type here, although this means that buyers are now not using high-tech metals anymore. We don’t have the compact option and would instead have to opt for the slightly larger Diver 300m Co-Axial Master Chronometer “007 Edition” (Ref. 210.90.42.20.01.001).
The basic design of the watches from 2021 and 2014, as well as the original model from 1957, is very similar (see overview photo below). However, at second glance, some differences become apparent. The new watch only has the historic “Seamaster 300” logo and text on the dial; the second hand ends with a luminous “lolipop” dot instead of an arrow, a feature that was used for the very popular “Spectre” limited edition from 2015 (Ref. 233.32.41.21.01.001); and the 3, 6, 9 and 12 hour markers are also now beige-brown, like the triangular hour markers, instead of silver (and often mistaken for white). This is mainly due to the new dial design. In 2014, the triangles were recessed and filled with a vintage-style luminescent material, often described as “faux patina” (or “fauxtina”). Now, Omega is using a sandwich dial with a luminescent baseplate and a perforated top layer with cutouts for the hours. As usual, most of the display glows blue in the dark, but the minute hand and corresponding zero point on the rotating bezel stand out in green.
The bezel is also covered entirely with luminous material. In addition to the luminous dots, the previous model also had silver numerals made from Liquidmetal alloy. In those days, the basic bezel material was ceramic; today it is aluminum. We see the advantage of the new model as a more uniform color scheme and higher screen brightness. The downside here is that the scratch resistance of the diving bezel is less than before.
The screw-down crown, which guarantees the 300-meter water resistance listed in the watch’s name, is slightly smaller on the new model but its conical shape makes it as ergonomic as the cylindrical crown of its predecessor. As before, it can still be used in the half-pulled position to move the hour hand forward or backward, useful when crossing time zones or switching from daylight saving time to standard time . The stop seconds mechanism ensures accuracy whenever the time is reset. This now popular technology stops the second hand whenever the crown is fully pulled out.
Bracelet
Omega has also revised the details of the strap. Like so many of Biel’s other classic-style models, the strap tapers toward the clasp. Additionally, product designers have switched polished and matte surfaces so that now, as in 1957, the polished surface is on the outer links. The visual effects are amazing. The whole watch looks more elegant thanks to the tapered strap with polished links on the outside. That’s the advantage. The disadvantages? The outer links are more exposed than the inner links, as is the bezel, increasing the possibility of scratches. But it should be noted that in our wear test, over a period of several weeks, there were hardly any scratches on the bracelet or on the bezel.
The well-made clasp remains virtually unchanged. The folding hook is sturdy, safe and easy to use thanks to its side opening structure and two deployment buttons. A huge advantage: inside there is a patented quick extension with three locking levels that can be operated with a push-button slider to adjust the length. For example, you can lengthen the bracelet by one or two 1.9 mm increments for more comfort on a hot day. This is less than the six increments the previous model offered, so be very careful during the initial bracelet sizing process. There are full and half links to ensure comfort, so after some trial and error, you’re sure to find the right length.
A sturdy pin inside the links is held in place by screws on both sides of the bracelet. Omega also holds the patent for this high-end detail. After adjusting the appropriate strap length, the Seamaster 300 is very comfortable to wear from morning to night.
Move
The sapphire crystal caseback no longer has a smooth rounded edge but a wave-shaped fluted edge, which can be found on most Seamaster models today. A large transparent window allows you to see the precise, individually decorated anti-magnetic components that make up the in-house made 8912 automatic movement. This movement has an identical structure to the Caliber 8400 used in the 2014 generation and was also evaluated by the Swiss Federal Institute of Metrology.
(META). The technical advantages remain the same; The rotor rotates in both directions and provides an above-average power reserve of 60 hours. The silicon hairspring can ensure extremely precise speeds even when subjected to temperature fluctuations or impacts. The balance wheel is mounted below the bridge for better stability and safety than a single-sided balance tap; Four weights ready for fine adjustment allow it to “breathe” comfortably. And last but not least, Omega’s coaxial escapement with multi-level pallets and escape wheel provides consistent impulse transmission for even greater precision.
All the structural advantages of the in-house movement pushed Omega to go beyond the speed test carried out by the official Swiss horology agency COSC and the company began sending its watches to the agency. METAS inspection agency for additional certification. Fully assembled watches are tested for functional reliability, speed stability, water resistance, power reserve and resistance to extremely strong magnetic fields of up to 15,000 gauss.
A watch that passes all of these tests will be certified by METAS as a Master Chronometer. Due to the significant number of watches Omega produces, the testing agency has a subsidiary in the Omega building in Biel. The independence of the inspections, verified according to the contract of both partners, is always guaranteed.
And our test watch? It adheres to its commitment to high quality standards, both on the chronograph and on the wrist. Electronic testing showed an increase of 4.2 seconds per day, but only 2 seconds when worn on the wrist. The individual positions are only 4 seconds apart, which is even more difficult to achieve than a small average deviation.
This Seamaster 300 movement offers the same advantages as the previous generation, although the above-average performance of the movement and the entire watch case is officially certified by METAS, which has inspired for Omega offers a 5-year warranty on its Master Chronometer.
Diving property
In our testing, the watch proved itself to be high quality, durable, accurate, easy to use and comfortable to wear. However, one drawback needs to be mentioned. The bezel – easy to grip – extends beyond the edges of the case for ease of use, but this can cause it to shift out of place when you reach into a pocket or through a backpack strap. In our wear test, not a day went by without the rotating bezel moving accidentally. For those who really intend to use the $6,500 watch as a diving backup, Omega is sure to offer more suitable options in the Seamaster line. The Co-Axial Master Seamaster 300 chronograph tested here is ideal for water sports but is not necessarily suitable for diving. Same with the stainless steel bracelet: the extension isn’t long enough to go over a wetsuit (you can buy the extra-long fabric strap separately).
The bezel’s lack of minute markers also shows that Omega’s intention here was to create a harmonious classic design and not necessarily a rugged tool watch. Overall, therefore, the Seamaster 300 is recommended more for everyday wear or recreational sports as well as for festive occasions — wherever it can maximize its advantages.
New and old beats?
Is the new generation Seamaster 300 better than the old one? Consider the fully illuminated bezel, a more harmonious color scheme with a uniform beige-brown display, a more elegant strap, METAS certification with a 5-year warranty, and a new blue stainless steel version blue. There are objections, but they are fewer in number: the bezel is more susceptible to scratches, the clasp has a shorter quick-adjust length, and the “lollipop” seconds hand may not be to everyone’s taste. (we prefer the arrow-tipped second hand). also used on other Omega models such as the Moonwatch and it performs the diving safety control function almost like a large lollipop needle). Overall, the subtle design updates on the new Seamaster 300 have resulted in a more balanced and refined appearance, while the technology, functions, execution and finishing on the watch leave much to be desired. wait. In short, the generational shift has been successful in every way.
