The Swatch x Blancpain Scuba Fifty Fathoms PINK OCEAN is reference SO35P400, a 42.3 mm automatic Swatch collaboration watch with a pink Bioceramic case, a 50-fathom manufacturer rating and a recycled-fishing-net NATO-style strap. It is a Swatch interpretation of Blancpain’s Fifty Fathoms, not a conventional Blancpain Fifty Fathoms model.
What is the PINK OCEAN?
PINK OCEAN is one of the Bioceramic Scuba Fifty Fathoms collaboration watches. Swatch describes the color inspiration as pink lakes, beaches and bays. The UK product page shows a pink case and crown, a gradient dial and a date indicator positioned between 4 and 5 o’clock: Swatch UK’s PINK OCEAN listing.
The collaboration should not be confused with Blancpain’s separate Fifty Fathoms watches. Swatch Group announced the collection on September 7, 2023, describing its five original models as a tribute to Blancpain’s Fifty Fathoms, which the brand says launched in 1953: Swatch Group’s announcement. Blancpain’s collaboration document characterizes the watches as playful interpretations with distinctive colors: Blancpain’s collaboration document.

What the water-resistance rating does—and does not—say
Swatch lists the watch at 50 fathoms, equivalent on its listing to 91 m, 300 ft or 9 bar. That is the manufacturer’s stated rating; the figure alone does not establish that the watch is suitable for a particular kind of diving. Swatch’s collection page also uses the 50-fathom / 91 m / 300 ft / 9 bar rating: Swatch US collection page.
Price and availability depend on market
When checked for this article on October 5, 2026, Swatch’s UK product page listed PINK OCEAN at £370, while its Finland page listed it at €430. These are separate localized listings, not a single global price; prices and stock can change. Swatch Group’s announcement says selected Swatch stores began selling the original collection on September 9, 2023, but that launch information does not establish present-day local availability.

The US collection page displayed $445 for Atlantic Ocean, Pacific Ocean and Indian Ocean—not for PINK OCEAN—so it does not establish a US price for SO35P400. That page describes the collection as non-limited and says selected Swatch stores sell the watches subject to a limit of one watch per person, per store, per day. Treat those as collection-page terms, which may be market-specific, and confirm current policy and stock with the local Swatch store or regional product page before making a trip.

PINK OCEAN combines a vivid colorway and a prominently sized case with an automatic movement and a strap made from recycled fishing nets. Its 42.3 mm diameter, 14.4 mm thickness and 48.0 mm lug-to-lug measurement give a more useful starting point for judging proportions than the color alone. The listed measurements do not determine how it will wear on every wrist, and the official information cited here does not verify compatibility with third-party replacement straps.
