OMEGA Seamaster Diver 300M 44 mm, titanium – tantalum – Sedna™ gold on titanium – tantalum – Sedna™ gold 210.60.44.51.03.001

Description

Since 1993, the Seamaster Professional Diver 300M has enjoyed a legendary following. This 44 mm chronograph is a Numbered Edition model and is built from grade 2 titanium, 18K Sedna™ gold and tantalum, which can be found on the base of the bezel and the middle links of the bracelet.

The 18K Sedna™ gold bezel ring features a laser-ablated diving scale, while the polished blue ceramic [ZrO2] dial is distinguished by laser-ablated waves, a date window at 6 o’clock, and subdial rings with touches of 18K Sedna™ gold.

The side of each case includes an 18K Sedna™ gold plate engraved with each unique Numbered Edition number. Turning the watch over reveals an OMEGA Seahorse, which has been laser-engraved and lacquered white on the sapphire crystal. Through the glass, you can see the OMEGA Co-Axial Master Chronometer Calibre 9900, certified by the Swiss Federal Institute of Metrology (METAS).

Features

• 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.
• Chronometer: Label given to a watch which has been successfully tested by an accredited and independent laboratory in order to receive a certificate compliant with the chronometer ISO 3159 standard.
• 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.
• 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).
• Numbered edition: A watch series each of whose pieces is numbered sequentially in the order it is produced.
• Screw-in crown: Self-locking crown, screwed into the tube of the case, used for highly water resistant divers’ watches.
• Small seconds: A hand on a sub-dial which tracks seconds typically it completes a full rotation in one minute.
• Time zone function: Allows the hour hand to be easily adjusted to different time zones without stopping the watch.
• 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.
