The OMEGA Seamaster Ploprof 1200M Summer Blue, reference 227.32.55.21.03.001, brings a gradient-blue finish to the large, monobloc-cased diver. OMEGA presents its design as a link to the brand’s 1970s original; the connection is one of heritage and design, not evidence that the modern watch repeats the historic construction unchanged. Here are the manufacturer’s specifications, design details and available price context.
What is the Ploprof 1200M Summer Blue?
It is a Summer Blue edition of OMEGA’s Seamaster Ploprof 1200M, identified by reference 227.32.55.21.03.001. OMEGA’s official video, published June 27, 2023, describes the model as inspired by the 1970s original. The brand characterizes the design as a return of an icon; that framing signals a heritage connection rather than proving identical construction across generations. OMEGA’s Taiwan product listing and its official video provide the product details below.
Case, size and water-resistance rating
OMEGA specifies an O-MEGASTEEL monobloc case measuring 55 x 45 mm, 15.50 mm thick, with a 45 mm lug-to-lug length and 24 mm lug width. The crown is screwed in, and a security pusher at 2 o’clock has a blue ceramic ring. The product listing describes a blue rubber strap with a steel pin buckle.
OMEGA rates the watch to 120 bar, equivalent to 1,200 m or 4,000 ft. This is the manufacturer’s stated rating, not an independent test result presented here. The depth figure is only one part of a comparison: case footprint and thickness, materials, movement, dial and bezel design, and strap configuration also matter.

Summer Blue dial and bezel
The dial has a sun-brushed gradient-blue finish. OMEGA describes the bezel as sapphire crystal with blue lacquer on its reverse, while the security pusher’s blue ceramic ring adds another blue detail. The combination gives the edition its Summer Blue identity without changing its underlying Ploprof design language. These are manufacturer descriptions, not independent inspection findings.
Movement and technical specifications
The watch uses OMEGA’s automatic Calibre 8912. The manufacturer lists a 60-hour power reserve and 3.5 Hz frequency, and describes the movement as a METAS-certified Master Chronometer with resistance to 15,000 gauss.

Price and how to identify the exact model
OMEGA’s Taiwan product listing displayed NT$486,000 when accessed in 2026.

Check with OMEGA or an authorized retailer in your market for a local quote and availability.
When searching retailer catalogs, use the full reference number, 227.32.55.21.03.001, to distinguish this Summer Blue configuration from other Ploprof models. Availability at any specific retailer should be confirmed directly.

What to consider when comparing it with other divers
The 120-bar rating is a prominent specification, but it does not by itself establish how suitable a watch is for a particular owner or purpose. Compare the Ploprof with another professional diver using the same categories and verify the specifications for each exact reference:
- Dimensions: case width, thickness, lug-to-lug length and strap or bracelet fit.
- Construction: case material and any distinctive case or crown architecture.
- Rating: the stated water-resistance figure and how the manufacturer describes it.
- Movement: caliber, power reserve, frequency, certification and stated magnetic resistance.
- Display and configuration: dial and bezel design, strap or bracelet, and available colorways.
- Price: a current, region-specific figure for the exact reference.
The available specifications do not provide a complete numerical comparison with earlier Ploprofs or other dive watches. Compare predecessor figures only after checking their individual references and sources.
