Now sized in both 42 and 43.5 mm, every design detail has been rethought, including a new ceramic bezel with the diving scale in Ceragold™ or white enamel. All powered by Master Chronometer calibres, these watches offer extraordinarily high levels of precision, performance and magnetic resistance.
The sleek dials are made from ceramic and are available in black, white, 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.
"On the bezel, white enamel offers longer-lasting whiteness and durability."
Operated in a diving bell, one of the 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, meaning the watch remains water-resistant to 50m even if the valve is accidentally opened underwater.
"Adding symmetry to the watch, the date window has been moved to 6 o'clock."
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.
In total, there are 17 new Diver 300M models, including 8 in stainless steel, 8 in a mix of stainless steel and gold - and a model in Sedna™ gold. Each model is presented on an integrated black or blue rubber strap, or a traditional metal bracelet (with a new ergonomic design and a patented extendable foldover rack-and-pusher with diver extension).
