Since 1993, the Seamaster Professional Diver 300M has enjoyed a legendary following. OMEGA\u2019s 21st century models stay true to the original\u2019s dive watch design, while introducing exciting new materials and movements.<\/p>\n
On this 43.50 mm model, black ceramic [ZrO2] dominates. The case, bezel, wave-pattern dial, crown and helium escape valve, all in the same striking material, give the watch a very distinctive, uniform and sculptural look. To ensure visibility without affecting the overall aesthetic, OMEGA has introduced anthracite Super-LumiNova to the diving scale, the black PVD indexes and skeleton hands – and dot at 12H.<\/p>\n
Completing the look is an integrated black rubber strap with black ceramic buckle. Adding some light to the darkness is a window with a clear view of the movement. Visible through the sapphire-crystal on the wave-edged caseback is OMEGA\u2019s Co-Axial Master Chronometer Calibre 8806.<\/p>\n","protected":false},"featured_media":74259,"template":"","meta":{"_acf_changed":false},"product_brand":[116],"product_cat":[79,76],"product_tag":[],"product_collection":[155],"class_list":["post-208962","product","type-product","status-publish","has-post-thumbnail","product_brand-omega","product_cat-horlogerie","product_cat-neuf","product_collection-seamaster","first","instock","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":"Anti-magnetic<\/b> : The movement is unaffected by exposure to strong magnetic fields, even those greater than 1.5 tesla (15,000 gauss).
Chronometer<\/b> : 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.
Helium escape valve<\/b> : 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<\/b> : Guaranteeing the Swiss industry\u2019s highest standard of precision, performance and magnetic-resistance, as set by the Swiss Federal Institute of Metrology (METAS).
Screw-in crown<\/b> : Self-locking crown, screwed into the tube of the case, used for highly water resistant divers' watches.
Transparent caseback<\/b> : A transparent caseback - frequently made of sapphire - makes it possible to see the movement inside the watch.
Unidirectional rotating bezel<\/b> : 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.
