The Seamaster Professional Diver 300M has been a legend since its launch in 1993. This 44 mm numbered-edition chronograph is crafted from grade 2 titanium, Sedna\u2122 18K gold and tantalum, which are found on the base of the bezel and the central links of the bracelet.The Sedna\u2122 18K gold bezel features a laser-engraved diving scale. The polished blue [ZrO2] ceramic dial, meanwhile, is embellished with laser-engraved waves and a date window at 6 o’clock. The counter rings are also enhanced with 18K Sedna\u2122 gold.On the side of the case, an engraved 18K Sedna\u2122 gold plate indicates the numbered edition. The sapphire crystal caseback is decorated with the laser-engraved OMEGA seahorse and lacquered white. Through the sapphire crystal can be admired the OMEGA Co-Axial Master Chronometer caliber 9900, certified by the Swiss Federal Institute of Metrology (METAS). <\/p>\n","protected":false},"featured_media":74034,"template":"","meta":{"_acf_changed":false},"product_brand":[396],"product_cat":[491,493],"product_tag":[],"product_collection":[439],"class_list":["post-172490","product","type-product","status-publish","has-post-thumbnail","product_brand-omega-en","product_cat-new","product_cat-watches","product_collection-seamaster-en","first","outofstock","shipping-taxable","purchasable","product-type-simple"],"acf":{"product_is_new":false,"product_not_available":false,"product_related_stores":null,"product_infos":"","product_features":[{"title":"Features","description":"Antimagnetic<\/b>: The movement resists magnetic fields in excess of 1.5 tesla (15,000 gauss).
Master Chronometer certification<\/b>: This certification guarantees the highest level of precision, performance and magnetic resistance in Swiss industry, as established by the Swiss Federal Institute of Metrology (METAS).
Chronograph<\/b>: The chronograph function is a mechanism for measuring time intervals. A chronograph watch can therefore time events while continuing to indicate the time in the same way as a traditional watch.
Chronometer<\/b>: Designation of a watch that has passed precision tests and received a certificate from an official organization (the COSC).
Screw-in crown<\/b>: self-locking crown screwed into the case tube, used for highly water-resistant diving watches.
Date<\/b>: The day of the month, displayed in an aperture on the watch dial at 3 or 6 o'clock, or in a counter at 9 o'clock.
Time zone function<\/b>: Allows the hour hand to be easily set to two time zones, without stopping the watch.
Transparent back<\/b>: A transparent back, often sapphire, allows the movement inside the watch to be seen.
Unidirectional rotating bezel<\/b>: Bezel turning in one direction only. Particularly useful for divers, as they can't accidentally turn it in the wrong direction and thus miscalculate their dive times. A rotating bezel makes it easier to measure elapsed time.
Small seconds<\/b>: Sub-dial hand marking the seconds. It usually completes one full rotation in one minute.
Helium valve<\/b>: Decompression system allowing helium to escape from the watch when worn by professional divers (long-term underwater work, offshore oil exploration, etc.).
Numbered edition<\/b>: A series of watches in which each piece is sequentially numbered in the order in which they are produced.
