OMEGA Seamaster Ploprof 1200M "Summer Blue" | O-MEGASTEEL | Ref. 227.32.55.21.03.001 | Full Set
This timepiece is in pristine condition with no signs of wear. It comes as a complete set including both inner and outer boxes, manual, Pictograms card, Master Chronometer card, and warranty card dated June 13, 2025. Manufacturer warranty active through June 2030. MSRP: 16,100 USD.
Drawing direct inspiration from the legendary Professional Plongeur (Ploprof) of the 1970s, the Ploprof 1200M is a 55 x 45mm asymmetric saturation-dive instrument in O-MEGASTEEL — the manufacture's proprietary steel alloy — measuring 15.5mm in thickness. The unidirectional rotating bezel is constructed entirely from sapphire crystal, varnished blue on the reverse to reveal the light blue diving scale beneath, creating a translucent and visually unique presentation. The sun-brushed Summer Blue gradient dial deepens in tone toward the edges to reflect the watch's extraordinary depth rating of 1,200 meters / 4,000 feet, with applied luminescent hour markers, an oversized blue minute hand for legibility underwater, a power reserve indicator, and a helium escape valve at 10 o'clock. The hex-threaded crown is positioned at 9 o'clock within a protective crown-guard — an engineering solution dating to the dive tool's 1970s DNA. Presented on a blue rubber strap with pin buckle. Retailing at 16,100 USD, this example is offered meaningfully below current retail. The in-house 8912 is a self-winding Co-Axial Master Chronometer movement certified by both COSC and METAS — resistant to magnetic fields exceeding 15,000 gauss — comprising 39 jewels and twin barrels in series, beating at 25,200 vph, and delivering approximately 60 hours of power reserve, water-resistant to 1,200 meters.
