This one does it in white — and that single decision changes the entire character of the watch. The 42 mm stainless steel case carries a black ceramic bezel with a white enamel diving scale, while the dial itself is polished white ceramic, laser-engraved with the Seamaster wave pattern and with \"Seamaster\" picked out in red. The blackened skeleton hour and minute hands are filled with white Super-LumiNova, and the seconds hand carries a varnished red tip. In daylight the dial reads almost like lacquered porcelain; the waves only reveal themselves as the wrist turns.\u003c\/p\u003e\n\u003cp\u003eThe suffix matters here. Within the fourth-generation Diver 300M family, 210.32 denotes the strap configuration rather than the steel bracelet — this reference is presented on an integrated black rubber strap and driven by the OMEGA Master Chronometer Calibre 8800, visible through the sapphire-crystal wave-edged caseback. Black rubber against a white ceramic dial is the most graphic combination Omega offers in this collection, and it is the version that most convincingly reads as a modern tool watch rather than a dress diver.\u003c\/p\u003e\n\u003cp\u003eThis example has been worn and enjoyed. BST grades it Good Pre-Owned: there are signs of wear throughout, and the case in particular shows its history — nothing egregious, but this is an honest, lived-with watch rather than a safe queen. On the timing machine at BST it recorded +3 seconds per day with 327 degrees of amplitude at the time of inspection.\u003c\/p\u003e\n\u003cp\u003eIt arrives with box, papers and cards, though the warranty card is undated. Year of manufacture is not established, so we list it as unknown rather than guess. The rubber strap is sized to fit an approximately 8-inch wrist.\u003c\/p\u003e\n\u003ch3\u003e🕰️ The Evidence\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eReference:\u003c\/strong\u003e 210.32.42.20.04.001\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 Unknown\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\u003eDial:\u003c\/strong\u003e Polished white ceramic with laser-engraved waves and \"Seamaster\" in red; applied stick indices; date at 6 o'clock\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHands:\u003c\/strong\u003e Blackened skeleton hour and minute hands with white Super-LumiNova; red-tipped seconds hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCrystal:\u003c\/strong\u003e Domed scratch-resistant sapphire with anti-reflective treatment on both sides\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBezel:\u003c\/strong\u003e Black ceramic unidirectional rotating bezel with white enamel diving scale\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCrown:\u003c\/strong\u003e Screw-down\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelium Escape Valve:\u003c\/strong\u003e Located at 10 o'clock on the case flank\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCaseback:\u003c\/strong\u003e Wave-edged with sapphire-crystal display window\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMovement:\u003c\/strong\u003e OMEGA Co-Axial Calibre 8800, automatic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCertification:\u003c\/strong\u003e Master Chronometer, COSC-certified, co-axial escapement\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower Reserve:\u003c\/strong\u003e 55 hours\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAnti-Magnetism:\u003c\/strong\u003e Resistant to magnetic fields greater than 1.5 tesla (15,000 gauss)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunctions:\u003c\/strong\u003e Hours, minutes, seconds, date\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWater Resistance:\u003c\/strong\u003e 300 metres\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStrap:\u003c\/strong\u003e Integrated black rubber strap\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFit:\u003c\/strong\u003e Approximately 8-inch wrist\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTiming at Inspection:\u003c\/strong\u003e +3 seconds per day, 327 degrees amplitude\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCondition:\u003c\/strong\u003e Good Pre-Owned — signs of wear throughout, most evident on the case\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFactory Warranty:\u003c\/strong\u003e Warranty card present but undated; remaining coverage cannot be confirmed\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 fourth generation of the Seamaster 300M arrived at Baselworld 2018, bringing back the wave dial in a new form and introducing the Co-Axial Master Chronometer Calibre 8800. It was a comprehensive redraw of a watch that had been in continuous service since 1993 — recessed date moved to six o'clock, ceramic dial and bezel, skeleton hands, conical helium valve, sapphire caseback where there had once been solid steel. For collectors, 2018 is the dividing line in Seamaster 300M history, and everything after it belongs to a distinctly different watch.\u003c\/p\u003e\n\u003cp\u003eThe white dial occupies an unusual position within that family. Black and blue are the volume sellers and the versions most people picture when the Seamaster is mentioned; white ceramic is the outlier, and it is encountered noticeably less often on the secondary market than its darker siblings. It also reads very differently on the wrist — brighter, more graphic, closer in spirit to a sailing or beach watch than to a saturation-diving instrument.\u003c\/p\u003e\n\u003cp\u003eConfiguration is worth attention too. The 210.30 prefix denotes the same white dial on the steel bracelet; 210.32.42.20.04.001 is specifically the white-dial, black-bezel version fitted on rubber. Buyers who search only by model name frequently miss the distinction. Anyone shopping for the rubber-strap version specifically is shopping for this reference.\u003c\/p\u003e\n\u003ch3\u003e🌟 Technical Provenance\u003c\/h3\u003e\n\u003cp\u003eCalibre 8800 is the compact-diameter member of Omega's Master Chronometer family, and it is the reason the modern Seamaster behaves the way it does. It is a self-winding, COSC-certified Master Chronometer movement with co-axial escapement, 55 hours of power reserve, 35 jewels and a 25,200 vph beat rate.\u003c\/p\u003e\n\u003cp\u003eThe headline capability is magnetic resistance. The movement is unaffected by exposure to magnetic fields greater than 1.5 tesla — 15,000 gauss — achieved through non-ferrous materials in the escapement and balance rather than the soft-iron cage approach used elsewhere in the industry. That means no protective inner case, which is precisely why Omega could fit a display caseback to a 300-metre diver without compromise.\u003c\/p\u003e\n\u003cp\u003eMaster Chronometer certification is administered by METAS and layers eight tests on top of COSC chronometry, including performance in a magnetic field and rate measurement in multiple positions and power-reserve states. It is a meaningfully stricter standard than chronometer certification alone, and it applies to the cased-up watch rather than the bare movement. At BST inspection this example returned +3 seconds per day with 327 degrees amplitude — a snapshot taken on our timing machine, not a guarantee of long-term rate.\u003c\/p\u003e\n\u003ch3\u003e🧾 From the Case File\u003c\/h3\u003e\n\u003cp\u003eThe practical argument for the rubber-strap version is simple: it is the more wearable configuration in warm weather and around water, and it sheds a noticeable amount of weight compared with the steel bracelet. The strap is integrated into the case, so the transition from lug to strap is unbroken and the watch sits close and flat rather than perching. As supplied, it is fitted for an approximately 8-inch wrist.\u003c\/p\u003e\n\u003cp\u003eThe white dial is the most legible in the range in bright conditions, and the black hands give a level of contrast that darker dials achieve only through lume. With 300 metres of water resistance, a screw-down crown and a helium escape valve, nothing about the watch is decorative — it simply happens to be handsome.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCondition\u003c\/strong\u003e is where this example asks for honesty rather than persuasion. It is Good Pre-Owned, with wear present throughout and a case that carries visible evidence of daily use. If a flawless example is the objective, this is not that watch. If the objective is a discontinued-configuration Seamaster that has already taken its knocks and can be worn without anxiety — on rubber, in the water, on holiday — the calculation changes considerably. A ceramic dial and ceramic bezel are also the two surfaces least likely to record further wear, so the parts you look at most will stay as they are.\u003c\/p\u003e\n\u003cp\u003eThe set is complete in the useful sense: box, papers and cards accompany the watch. The warranty card is undated, so we make no claim about remaining factory coverage.\u003c\/p\u003e\n\u003ch3\u003e🗝️ BST Verdict\u003c\/h3\u003e\n\u003cp\u003eA fourth-generation Seamaster Diver 300M in its least common and most graphic form — white ceramic dial, black ceramic bezel, integrated rubber — powered by the anti-magnetic, METAS-certified Calibre 8800.\u003c\/p\u003e\n\u003cp\u003eHonestly worn and honestly described. The case shows its history, the timing was healthy at inspection, and the box, papers and cards are present.
