First introduced in 1993, this year, the Omega Seamaster 300m collection celebrates 25 years with a full makeover from the inside out. The original design and ocean spirit are still there, but now with advanced materials and updates in every model.

The new watch is 42 mm, with each detail rethought. This rethink includes a new ceramic bezel with the diving scale in Ceragold™ or white enamel. Inside, the watches include the Master Chronometer Calibre 8800, which offers higher levels of precision, performance and magnetic resistance.

The dials are made from ceramic and are available in black, blue or PVD chrome. The wave pattern has been reintroduced (now laser-engraved) and the indexes have been raised and filled with Super-LumiNova. And the skeleton hands have been subtly reshaped.

On the new models, the 300m’s helium valve has been given a new conical shape and has been patented by OMEGA with technology that allows it to be operated underwater.

The reverse of the watch over reveals a wave-patterned edge on the caseback, as well as sapphire crystal, through which can be viewed the METAS-approved Master Chronometer Calibre 8800.

The new 300m Diver collection offers 14 new models, including 6 in stainless steel and 8 in a mix of stainless steel and gold. Each model is presented on an integrated black or blue rubber strap, or a traditional metal bracelet (with a new patented extendable foldover rack-and-pusher with diver extension.
