This one makes it with surface. The dial is sun-brushed PVD chrome-colour ceramic with laser-engraved waves and a date window at 6 o'clock — a grey that shifts from near-silver to gunmetal as the light moves across the engraved wave pattern, rather than sitting flat the way a painted dial would. The market has settled on the nickname \"Grey Wave,\" and it is an accurate one.\u003c\/p\u003e\n\u003cp\u003eAgainst that cool grey, Omega set a blue ceramic bezel with a white enamel diving scale, with blued skeleton hands and raised indexes filled with white Super-LumiNova. It is the least obvious colour combination in the Diver 300M line-up and arguably the most interesting one: the blue reads as a deliberate accent instead of the dominant theme.\u003c\/p\u003e\n\u003cp\u003eThis example is a 2022 watch in Excellent Pre-Owned condition, presented on its factory blue rubber strap with the stainless steel pin buckle, and currently sized to fit an approximately 8-inch wrist. It is accompanied by its box, papers, and cards. No specific condition flaws were recorded during BST's physical inspection.\u003c\/p\u003e\n\u003cp\u003eInside is the Co-Axial Master Chronometer Calibre 8800, visible through the sapphire caseback — the self-winding, METAS-certified movement that defines the current generation of the Diver 300M.\u003c\/p\u003e\n\u003ch3\u003e🕰️ The Evidence\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eReference:\u003c\/strong\u003e 210.32.42.20.06.001\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eModel \/ Collection:\u003c\/strong\u003e Omega Seamaster Diver 300M Co-Axial Master Chronometer 42 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eYear:\u003c\/strong\u003e 2022\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCase:\u003c\/strong\u003e Stainless steel, brushed and polished\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCase Diameter:\u003c\/strong\u003e 42 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness:\u003c\/strong\u003e 13.56 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLug-to-Lug:\u003c\/strong\u003e 49.90 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLug Width:\u003c\/strong\u003e 20 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDial:\u003c\/strong\u003e Grey sun-brushed PVD chrome-colour ceramic, laser-engraved waves, date at 6 o'clock\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCrystal:\u003c\/strong\u003e Domed scratch-resistant sapphire crystal with anti-reflective treatment on both sides\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBezel:\u003c\/strong\u003e Unidirectional rotating, blue ceramic with white enamel diving scale\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCrown:\u003c\/strong\u003e Screw-in crown; conical helium escape valve\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCaseback:\u003c\/strong\u003e Transparent sapphire caseback\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMovement:\u003c\/strong\u003e Omega Calibre 8800\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMovement Type:\u003c\/strong\u003e Self-winding (automatic)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCertification:\u003c\/strong\u003e Co-Axial Master Chronometer, METAS certified; resistant to magnetic fields greater than 1.5 tesla (15,000 gauss)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower Reserve:\u003c\/strong\u003e 55 hours\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunctions:\u003c\/strong\u003e Hours, minutes, central seconds, date\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWater Resistance:\u003c\/strong\u003e 30 bar (300 metres \/ 1000 feet)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStrap:\u003c\/strong\u003e Blue rubber strap\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClasp:\u003c\/strong\u003e Stainless steel pin buckle\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFit:\u003c\/strong\u003e Approximately 8-inch wrist\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCondition:\u003c\/strong\u003e Excellent Pre-Owned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded:\u003c\/strong\u003e Box, Papers, and Cards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e🌟 Collector Provenance\u003c\/h3\u003e\n\u003cp\u003eThe Seamaster Professional Diver 300M has had a devoted following since 1993, and the modern collection takes that ocean heritage and rebuilds it around Omega's current innovation and design language. The 2018 redesign is the dividing line that matters most to collectors: it brought the case to 42 mm, replaced the painted wave dial with a laser-engraved ceramic one, moved the date to 6 o'clock, reshaped the helium escape valve, and introduced the sapphire caseback to a model that had worn solid backs for most of its life.\u003c\/p\u003e\n\u003cp\u003eThat generation also moved the collection onto the Master Chronometer standard. The Calibre 8800 is the time-and-date member of Omega's Co-Axial family, built around a silicon balance spring and certified by METAS rather than COSC alone — a testing protocol applied to the cased-up watch rather than the loose movement.\u003c\/p\u003e\n\u003cp\u003eWithin that generation, the grey ceramic dial occupies a quieter corner than the black-and-black or blue-and-blue variants that dominate the line. It is a configuration encountered less frequently in the wild than the headline colourways, and the pairing of a cool grey dial with a blue bezel and blue rubber gives the watch an identity distinct from the rest of the family.\u003c\/p\u003e\n\u003ch3\u003e🌟 Technical Provenance\u003c\/h3\u003e\n\u003cp\u003eThe Diver 300M has always been a working dive watch rather than a dress watch in diver's clothing, and this reference keeps the hardware that justifies the claim: 300 metres of water resistance, a unidirectional ceramic bezel, a screw-in crown, and the helium escape valve at 10 o'clock that has been part of the Seamaster Professional's identity since the beginning.\u003c\/p\u003e\n\u003cp\u003eThe anti-magnetic specification is the part owners actually notice in daily life. The movement is unaffected by magnetic fields greater than 15,000 gauss — enough to shrug off laptop speakers, tablet covers and magnetic clasps that would send a conventional hairspring badly off rate. Combined with a 55-hour power reserve, the watch tolerates a weekend off the wrist and the ordinary magnetic hazards of a modern desk.\u003c\/p\u003e\n\u003ch3\u003e🧾 From the Case File\u003c\/h3\u003e\n\u003cp\u003eAt 42 mm with a 49.90 mm lug-to-lug, this is a full-size sports watch that still stays within the footprint of most wrists — and on a rubber strap rather than the steel bracelet, it wears noticeably lighter than its dimensions suggest. The strap is already sized for an approximately 8-inch wrist, and the 20 mm lug width makes alternatives straightforward to source should a buyer want to rotate between rubber and something else.\u003c\/p\u003e\n\u003cp\u003eThe rubber configuration is also the most practical way to own this watch. It is the version you can take into salt water, onto a boat, or through a summer without thinking about it, and the grey dial handles that duty while looking considerably less utilitarian than a black-dial diver.\u003c\/p\u003e\n\u003cp\u003eCompared with buying the reference new, the case here is straightforward: a 2022 example in Excellent Pre-Owned condition, complete with its box, papers and cards, and carrying the same Master Chronometer certification as a current-production piece. Buyers should note that any remaining coverage under Omega's five-year factory warranty depends on the exact activation date recorded on the warranty card and on Omega's warranty terms.\u003c\/p\u003e\n\u003ch3\u003e🗝️ BST Verdict\u003c\/h3\u003e\n\u003cp\u003eThe most quietly distinctive dial in the current Diver 300M range, on the strap configuration that suits the watch's purpose best. The grey ceramic surface earns its nickname, and the blue bezel keeps it unmistakably Seamaster.\u003c\/p\u003e\n\u003cp\u003eA complete, well-kept 2022 example of a reference that does everything the modern Omega diver is supposed to do — and looks like rather fewer of them while doing it.\u003c\/p\u003e\n\u003cp\u003e👉 Every case deserves a closer look.\u003c\/p\u003e","brand":"Baker Street Timepieces","offers":[{"title":"Default Title","offer_id":58723332030767,"sku":null,"price":4000.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0948\/5359\/5439\/files\/BST_7219.jpg?v=1793056565","url":"https:\/\/bakerstreettimepieces.com\/products\/case-730-omega-seamaster-diver-300m-ref-210-32-42-20-06-001","provider":"Baker Street Timepieces","version":"1.0","type":"link"}
