The Seamaster Professional Diver 300M has been a legend since its launch in 1993. The contemporary collection honours its maritime heritage by combining it with the best of OMEGA innovation and design.This 44 mm stainless steel and 18K Sedna\u2122 gold chronograph is topped by a polished black ceramic bezel featuring a Ceragold\u2122 diving scale. The pushers are also in polished black ceramic, as is the dial, decorated with laser-engraved waves, which features a date window at 6 o’clock. The counter hands are in 18K Sedna\u2122 gold, as are the other hands and indexes, which are also coated in white Super-LumiNova. The watch is presented on a stainless steel and Sedna\u2122 18K gold bracelet and driven by the OMEGA Master Chronometer caliber 9900, which can be admired through the wavy-edged sapphire crystal caseback. <\/p>\n","protected":false},"featured_media":73694,"template":"","meta":{"_acf_changed":false},"product_brand":[396],"product_cat":[491,493],"product_tag":[],"product_collection":[439],"class_list":["post-172531","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.).
