Seamaster Diver 300M
Ref.: 21030445106001
The Omega Seamaster Diver 300M Chronograph unites professional diving heritage with the technical mastery of the chronograph. The sun-brushed, PVD-treated chrome-colour grey ceramic dial is laser-engraved with the model’s signature wave pattern. The blue ceramic bezel and blue ceramic chronograph pushers create an elegant contrast with the grey. The 44 mm stainless steel case and steel bracelet with diver extension give the watch a powerful presence. The column-wheel calibre 9900, certified as a Master Chronometer by METAS, offers a 60-hour power reserve, a 12-hour chronograph and water resistance to 300 metres.
Weekday orders placed before 13:00 are dispatched the same day.
Within the Seamaster family, which has upheld its bond with the sea since 1948, the Diver 300M has been the icon of professional diving since 1993. The chronograph version takes this icon one step further. Alongside the time measured by the diving bezel, it adds a chronograph that records every second. Designed with a grey dial and blue ceramic details, this version presents technical depth in a sophisticated language of colour.
Measuring 44 mm in diameter and 17.20 mm in thickness, the 316L stainless steel case features a screw-in, self-locking crown and polished blue ceramic chronograph pushers. The polished blue ceramic ring of the unidirectional rotating bezel bears a diving scale filled with white enamel. Beneath a domed sapphire crystal glareproofed on both sides lies the sun-brushed, PVD-treated chrome-colour grey ceramic dial. The laser-engraved wave pattern on the dial gains a metallic depth with the angle of the light. Blue hands, including those on the subdials, indexes filled with white Super-LumiNova and a date window at 6 o’clock create a highly legible and balanced composition.
Through the wave-edged sapphire caseback, Omega’s automatic column-wheel chronograph calibre 9900 with Co-Axial escapement is on display. Equipped with a silicon balance spring and two barrels mounted in series, the movement operates at a frequency of 4 Hz and offers a 60-hour power reserve. Its Master Chronometer certification by METAS, the Swiss Federal Institute of Metrology, also covers magnetic resistance up to 15,000 gauss. The movement provides central chronograph seconds, 12-hour and 60-minute recorders, small seconds and a time-zone function that allows the hour hand to be adjusted independently when travelling. With its foldover clasp featuring a comfort setting and diver extension, the stainless steel bracelet carries the watch with confidence in every setting, from deep waters to the business world. It is a timepiece in which every detail rests on a decision, and every second on a legacy. As an authorised Omega retailer, Aykach presents this masterpiece with a guarantee of authenticity and invites you to discover it in person at its showroom in Çankaya, Ankara.
