For this new Seamaster, Omega has exploited the versatility of ceramic, in order to create a watch in contrasting shades but “coming” from a single color. The House has obviously remained faithful to the original design of the Diver 300M, a professional diving watch. The 43.5 mm diameter case with a polished and brushed surface finish is made of black ceramic [ZrO2] and is equipped with an integrated rubber strap (also black), with a ceramic buckle. The crown and the helium escape valve (located at 10) are also made of ceramic. Although the new Seamaster Diver 300M Black Black is characterized by the shade of black, the dial is easy to read in all situations. To ensure visibility without damaging the aesthetics of the watch, replica Omega has introduced the anthracite Super-LumiNova for the hands (blue emission for the hour and second hands, green for the minutes), hour markers (blue emission) and index of triangular reference (green emission) on the unidirectional rotating bezel. In addition, for the first time Omega performed laser ablation of almost all the details of the black ceramic dial. From the iconic waves, to the minute scale, to the writings and even the Omega logo, the details have been made in positive relief from a single piece. The back, in brushed and polished black ceramic, features a sapphire crystal porthole that opens the Omega Co-Axial Master Chronometer in-house caliber 8806 (35 jewels, 25,200 vibrations / hour, power reserve of 55 hours, resistant magnetic fields up to 15,000 Gauss, silicon spiral), automatic mechanical and certified by the Swiss Federal Institute of Metrology (METAS). The watch is covered by a 5-year warranty. Price: 8,700 euros rolex replica
