Introducing the 2021 Omega Seamaster 300 Master Chronometer

Omega introduces a new take on the Seamaster 300, sporting a certified Master Chronometer movement and various other updates. Enter the Seamaster 300 Master Chronometer!

The Omega Seamaster 300 was originally introduced in 2014 as a new take on one of Omega's earliest dive watches, the Seamaster 300 of 1957. The 2015 Seamaster 300 [on the left in the picture above] offered a pleasant mix of retro inspired aesthetics with state-of-the art technologies such as an in-house movement with co-axial escapement in the form of caliber 8400. The watch proved to be rather successful - to the extent that it was the weapon of choice of none other than James Bond in the Spectre movie.

For 2021, Omega introduces an entirely new generation of the Seamaster 300. Whilst arguably similar at first glance, the new Seamaster 300 sports a few interesting and notable changes compared to the 2014 generation. Lets's start with the innards. Replacing the 8400 is caliber 8912, a movement also found in the latest generation of the PloProf. In-line with many of the brand's latest offerings, the watch is now a METAS-certified Master Chronometer.

Turning over the watch, the front reveals proportions that have been delicately tweaked. The dial opening is slightly larger. The dial itself is of the so-called sandwich variety. This means that a base layer of SuperLuminova is covered by a second plate with cut-outs for the markers and numerals. No longer is there any mention of the movement's accolades. Rather Master Co-Axial Chronometer is replaced by a discrete Seamaster 300 text at 6:00, cleaning up the dial considerably. The second hand is of the lollipop variety, which brings to mind the Spectre limited edition of 2015. The case is slightly slimmer, whilst the sapphire crystal features a more pronounced dome. For the bezel, now slimmer than before, Omega returns to aluminum instead of ceramics on all but the Bronze Gold version.

Bronze Gold

Wait a moment - Bronze Gold? That's right. For the new Omega Seamaster 300 Omega introduces an entirely new -proprietary and patent-pending- alloy named Bronze Gold. According to Omega this bronze alloy consists of 50% copper, enriched with noble elements such as 37.5% gold, hallmarked as 9K, as well as palladium and silver. Unlike other bronze alloys it can be worn directly on the skin - so indeed no need for a titanium or stainless steel case back. Omega furthermore explains that Bronze Gold will age slowly and retain its natural and beautiful patina over a longer period of time without the the oft-dreaded verdigris-oxidation. The color? To stay in Omega-speak, it sits right in between Sedna and Moonshine gold. When new, that is.
