Reference 210.30.42.20.01.023 combines a grained black dial with a black ceramic relief bezel and a steel mesh bracelet. The Spectre identity continues on the back, with an engraved caseback and a black Spectre logo on the movement rotor.\u003c\/p\u003e\n\u003ch2\u003eWhat makes this Seamaster different?\u003c\/h2\u003e\n\u003cp\u003eThe appeal here is texture rather than a wave-pattern dial: the black face and relief bezel give the watch a restrained, monochromatic look. This is the Diver 300M Spectre Edition, not the earlier Seamaster 300 Spectre model.

The sapphire display back lets you see the movement. A screw-in crown, helium escape valve and 300-metre water-resistance rating retain the practical diving-watch architecture.\u003c\/p\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cdiv style=\"overflow-x:auto\"\u003e\u003ctable style=\"width:100%;border-collapse:collapse\"\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\" style=\"text-align:left;padding:10px;vertical-align:top\"\u003eManufacturer reference\u003c\/th\u003e\n\u003ctd style=\"padding:10px\"\u003e210.30.42.20.01.023\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\" style=\"text-align:left;padding:10px;vertical-align:top\"\u003eCollection\u003c\/th\u003e\n\u003ctd style=\"padding:10px\"\u003eSeamaster Diver 300M Spectre Edition\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\" style=\"text-align:left;padding:10px;vertical-align:top\"\u003eDial\u003c\/th\u003e\n\u003ctd style=\"padding:10px\"\u003eGrained black dial\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\" style=\"text-align:left;padding:10px;vertical-align:top\"\u003eBezel\u003c\/th\u003e\n\u003ctd style=\"padding:10px\"\u003eUnidirectional black ceramic bezel with relief diving scale and luminous dot at 12 o’clock\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\" style=\"text-align:left;padding:10px;vertical-align:top\"\u003eCase\u003c\/th\u003e\n\u003ctd style=\"padding:10px\"\u003e42 mm stainless steel; 50 mm lug-to-lug; 14.23 mm thick\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\" style=\"text-align:left;padding:10px;vertical-align:top\"\u003eBracelet\u003c\/th\u003e\n\u003ctd style=\"padding:10px\"\u003eStainless steel mesh with foldover clasp; 20 mm lug spacing\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\" style=\"text-align:left;padding:10px;vertical-align:top\"\u003eMovement\u003c\/th\u003e\n\u003ctd style=\"padding:10px\"\u003eOmega Calibre 8806 automatic Co-Axial Master Chronometer\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\" style=\"text-align:left;padding:10px;vertical-align:top\"\u003ePower reserve\u003c\/th\u003e\n\u003ctd style=\"padding:10px\"\u003e55 hours\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\" style=\"text-align:left;padding:10px;vertical-align:top\"\u003eFunctions\u003c\/th\u003e\n\u003ctd style=\"padding:10px\"\u003eHours, minutes and central seconds; no date\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\" style=\"text-align:left;padding:10px;vertical-align:top\"\u003eWater resistance\u003c\/th\u003e\n\u003ctd style=\"padding:10px\"\u003e300 metres \/ 30 bar\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\" style=\"text-align:left;padding:10px;vertical-align:top\"\u003eCrystal\u003c\/th\u003e\n\u003ctd style=\"padding:10px\"\u003eDomed scratch-resistant sapphire with anti-reflective treatment inside\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\" style=\"text-align:left;padding:10px;vertical-align:top\"\u003eCrown and valve\u003c\/th\u003e\n\u003ctd style=\"padding:10px\"\u003eScrew-in crown and helium escape valve\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\" style=\"text-align:left;padding:10px;vertical-align:top\"\u003eMagnetic resistance\u003c\/th\u003e\n\u003ctd style=\"padding:10px\"\u003e15,000 gauss\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\" style=\"text-align:left;padding:10px;vertical-align:top\"\u003eCaseback\u003c\/th\u003e\n\u003ctd style=\"padding:10px\"\u003eTransparent sapphire caseback with Spectre engraving; rotor bearing a black Spectre logo\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\" style=\"text-align:left;padding:10px;vertical-align:top\"\u003eTotal product weight\u003c\/th\u003e\n\u003ctd style=\"padding:10px\"\u003eApproximately 159 g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003c\/div\u003e\n\u003ch2\u003eHow sourcing works\u003c\/h2\u003e\n\u003cp\u003eContact our Buying Desk with reference \u003cstrong\u003e210.30.42.20.01.023\u003c\/strong\u003e.
