Updated and improved.

After having refreshed the Seamaster Diver 300m collection last year with Master Chronometer movements and the classic wave pattern dial – a throwback to the watch made famous by Pierce Brosnan’s James Bond – Omega has applied the facelift to the chronographs of the series.

Three variants of the updated Seamaster Diver 300m Chronograph were recently unveiled at Omega headquarters in Bienne, slated to replace the older Diver 300m Co-Axial Chronographs.

The primary updates to the new models include ceramic pushers on all of the 44mm watches that match the ceramic dials and bezels. And all the chronographs have applied hour indices on the are made of the same metal as the bezel (namely gold or steel) and filled with Super-LumiNova.

Base model in steel

The new steel Diver 300m Chronograph with a blue ceramic bezel and dial is perhaps the most traditional, given its resemblance to Seamaster chronographs of the 1990s that were powered by the Valjoux 7750.

The blue ceramic bezel insert features a white enamel diving scale, just like the time-and-date model from last year.

Steel and gold

In a similar vein, the two-tone Seamaster 300m Diver Chronograph in stainless steel with a bezel in Omega’s proprietary Sedna gold was an expected novelty.

However, given the inclusion of the chronograph counters on the dial, the watch seemed more balanced, with good contrast from the additional pops of colour.

That contrast of black against gold makes for a handsome, albeit slightly frilly watch.

Unlike the rhodium-plated steel hands on the steel and blue ceramic Diver 300m Chronograph, the bi-colour version has its hands in 18k Sedna gold, with the exception of the gold-coated central chronograph seconds hand.

And no-compromise gold

The highlight of the range this year, however, is the Diver 300m Chronograph in 18k Sedna gold.

Omega has gone to great lengths to ensure that the opulence of the watch doesn’t go unnoticed; this top of the line model is instantly distinguishable from from the bi-coloured version.

Unlike the ceramic bezels on the other models, this is laser-engraved, leaving it matte black with polished, relief markings. This laser engraving is done using the same process that produces wave-like pattern on the ceramic dial of the Seamaster Diver 300m.

Unlike the other watches in the range however, the dial of the 18k Sedna gold Chronograph is done in positive relief, just like the bezel. Instead of the waves being cut into the dial, the rest of the dial has been cut out to raise the waves from the surface.

In addition, the chronograph counters for the watch are ringed in 18k Sedna gold, further enhancing the sheer gold-ness of the watch.

The Master Co-Axial

The internal update to the model the most important aspect of the facelift, with with the movement now becoming a certified Master Chronometer, which means passing both COSC and METAS testing for timekeeping, functionality, and even magnetism resistance.

The steel and two-tone models are powered by the Cal. 9900. It features a column wheel, vertical clutch, and C0-Axial escapement.

The model entirely in 18k Sedna gold is powered by the automatic Cal. 9901, essentially a Cal. 9900 with the rotor and balance bridge in 18k Sedna gold. The Cal. 9901 found only in watches with Sedna gold cases.
