Today’s modern collection has embraced that famous ocean heritage and updated it with OMEGA’s best innovation and design. This 42 mm model is crafted from stainless steel and includes a blue ceramic bezel with a white enamel diving scale. The dial is also polished blue ceramic and features laser-engraved waves and a date window at 6 o’clock. The skeleton hands and raised indexes are rhodium-plated and are filled with white Super-LumiNova, while the helium escape valve has been given a conical design. The watch is presented on a blue rubber strap and is driven by the OMEGA Master Chronometer Calibre 8800, which can be seen through the sapphire-crystal on the wave-edged caseback.[/product_description] [unique_description_1]

• CHRONOMETER: ANTI MAGNETIC: The movement is unaffected by exposure to strong magnetic fields, even those greater than 1.5 tesla (15,000 gauss).
• CHRONOGRAPH: The chronograph function is a mechanism for measuring time intervals. A Chronograph Watch can therefore be used to time events while displaying the time like any traditional watch.
• DATE: The day of the month, displayed in a window on a watch dial at the 3 or 6 o’clock position, or within a subdial at 9 o'clock.
• 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).
• TRANSPARENT CASE BACK: A transparent caseback - frequently made of sapphire - makes it possible to see the movement inside the watch.
• 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.)
• SCREW IN CROWN: Self-locking crown, screwed into the tube of the case, used for highly water resistant divers' watches.
