Omega Seamaster Diver 300M 43.5mm Black Dial Black ceramic Strap 210.62.44.20.01.001

DESCRIPTION
Since 1993, the Seamaster Professional Diver 300M has enjoyed a legendary following. OMEGA’s 21st century models stay true to the original’s dive watch design, while introducing exciting new materials and movements.

This 43.50 mm model, cased in black ceramic [ZrO2] and Sedna™ gold, has a black ceramic dial with laser-ablated waves in positive relief. The polished Sedna™ gold indexes and facetted hands, filled with white Super-LumiNova, contrast beautifully with the black dial. Completing the look is an integrated black rubber strap with black ceramic buckle.

The polished-brushed oriented caseback with wave-edged design features OMEGA’s patented NAIAD LOCK. Powering the watch is OMEGA’s Co-Axial Master Chronometer Calibre 8806.

Features
Anti-magnetic: The movement is unaffected by exposure to strong magnetic fields, even those greater than 1.5 tesla (15,000 gauss).
Chronometer: Label given to a watch which has undergone precision tests and received a certificate from an official body (COSC).
Helium escape valve: Decompression system which allows helium to escape from inside the watch when the watch is worn for professional use in pressure chambers. (Long-term underwater work, crude oil exploration, etc.)
Master Chronometer Certified: Guaranteeing the Swiss industry’s highest standard of precision, performance and magnetic-resistance, as set by the Swiss Federal Institute of Metrology (METAS).
Screw-in crown: Self-locking crown, screwed into the tube of the case, used for highly water resistant divers’ watches.
Transparent caseback: A transparent caseback – frequently made of sapphire – makes it possible to see the movement inside the watch.
Unidirectional rotating bezel: A bezel which turns in only one direction. Particularly useful for divers who cannot accidentally rotate it in the wrong direction, which could cause them to miscalculate their dive times. A rotating bezel makes it easy to measure elapsed time.
