At BaselWorld 2018 Omega celebrated the 25th anniversary of the Seamaster 300M by launching the fourth generation of this highly popular (dare we say iconic?) dive watch. Below we'll briefly go over the specifics of each generation, using the full-size automatic in stainless steel / blue as our point of reference.



Omega Seamaster 300M - First Generation - 1993



The Omega Seamaster 300M was introduced in 1993 as a replacement for the Seamaster 200M. Compared to this earlier model it featured a more traditional case design, with key characteristics being the gently sweeping 'lyre' lugs (a reference to the Seamaster 300 of 1964 onward) and the unique scalloped bezel. Another signature is the wave pattern on the dial, which is found on all but a handful of the huge number of variations that was made of this generation.

The popularity of the Seamaster 300M made a huge jump when it was used in the 1995 James Bond 'GoldenEye' movie, a clever move devised by Jean-Claude Biver. While it was the quartz version that was used in this first installment of the Bond - Omega partnership, 'Bond' moniker has since been used for any Seamaster 300M with the blue dial, blue bezel insert, and 5-link bracelet. And the Seamaster 200M is now often referred to as the 'Pre-Bond'!

In our reference configuration this watch carried the reference number 2531.80.00. The earliest versions were powered by caliber 1109, though it most commonly seen with the 1120. Around 1997-1998 the luminescent material was upgraded from Tritium to Luminova.

Omega Seamaster 300M - Second Generation - 2006



The second generation of the Omega Seamaster 300M was introduced in 2006. For our reference model the biggest change was in the movement. Caliber 1120 found itself replaced by caliber 2500, which featured Omega's proprietary Co-Axial technology - though both are based on the ETA 2892. The dial received an update in the form of applied indexes, applied Omega logo & wording, and red Seamaster text. In our configuration this watch carried the reference number 2220.80.00.

Omega Seamaster 300M - Third Generation - 2012



The third mayor update of the Seamaster 300M collection was made in 2012. This time the movement remained unchanged, but the looks were updated quite drastically. The bezel insert of this generation was ceramic rather than aluminum, and the dial lost its waves in favor of a smooth glossy finish. In our configuration this watch carried the reference number

Omega Seamaster 300M - Fourth Generation - 2018



The fourth generation of the Seamaster 300M was introduced at BaselWorld 2018 in celebration of the 25th anniversary of the collection. Though still instantly recognizable as a Seamaster 300, the changes made are the biggest since the introduction of the original 1993 version. This generation is powered by Omega's high-tech caliber 8800, which is fully in-house, a-magnetic, and METAS-certified. At 42mm, the case is slightly larger than before, and it is fitted with a see-through caseback - a feature only found on a handful of earlier 300M's. Both the bezel insert AND the dial are made of ceramic, and the latter once again features the iconic wave pattern (now laser-engraved). The bracelet too is updated for a smoother look & more comfortable fit, plus it features a patented extendable foldover rack-and-pusher with diver extension. We expect the first ones to come in around mid-August, and you're welcome to drop by to see & try them!
