Omega Seamaster Diver 300M Chronometer 210.30.42.20.01.001

Since 1993, the Seamaster Diver 300M has enjoyed a legendary following. This year, the 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.

Now sized at 42 mm, every design detail has been rethought, including a new ceramic bezel with the diving scale in Ceragold™ or white enamel. Inside, the watches include the Master Chronometer Calibre 8800, instantly taking the collection into a higher realm of precision, performance and magnetic resistance.

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

One of the Diver 300M's most important details has always been its helium escape valve. For the new models, the valve has been given a conical shape and has been patented by OMEGA with an ingenious technology that allows it to be operated underwater.

Turning the watch over reveals a wave-patterned edge on the caseback, as well as sapphire crystal, through which you can see the METAS-approved Master Chronometer Calibre 8800
