Introducing The New Blancpain Fifty Fathoms, Now In Stainless Steel
With the new Fifty Fathoms in full steel, Blancpain bridges the past and present with this robust dive timer.
The name Fifty Fathoms is synonymous with Blancpain and the brand’s legacy of crafting dive watches that were actually used by professionals. Back in 1953, when it was first launched, Blancpain aimed to design a tool watch that would assist underwater divers on their missions.
- This led to the creation of the Fifty Fathoms—the first ‘modern’ diving watch, which was immediately adopted by pioneers of underwater diving and elite Marine Corps worldwide.
- The watch was designed to withstand the most extreme conditions, and featured innovations that were way ahead of its time, including:
- A secure crown system
- An automatic movement
- A contrasting dial with luminescent hour markers for maximum readability
- A lockable rotating bezel
- Anti-magnetic protection
- Advanced water resistance (50 fathoms, equivalent to 300 ft or 91.44m, a considerable range at the time).
New Blancpain Fifty Fathoms
The Fifty Fathoms has continued to evolve over decades, meeting the vital requirements of underwater diving, with an uncompromising commitment to timeless design and the latest technology. A new 42mm stainless-steel version now joins the brand’s permanent collection, following in the footsteps of previous iterations such as the Fifty Fathoms 70th Anniversary Act 1 unveiled in 2023, and the brushed grade-23 titanium and red gold versions launched last year.
The Blancpain Fifty Fathoms Goes All Steel
First launched in 2024, the 42mm version presents perfect proportions and refined aesthetics. After the brushed grade 23-titanium and red gold editions, the Fifty Fathoms is now available in polished stainless steel, a material that is both ultra-resistant and brilliantly shiny, creating striking light reflections from every angle.
- The sunburst black dial, enhanced by XXL luminescent indexes, offers optimal readability.
- The unidirectional black bezel with domed sapphire insert completes the glossy aesthetic of the piece.
- The model is offered on a stainless steel bracelet with impeccable finishes or a Tropic rubber strap with either a pin buckle or deployant clasp.

The Powerhouse—Blancpain Calibre 1315
At the heart of this Fifty Fathoms is calibre 1315. First launched in 2007, it embodies horological precision. Thanks to its three series-coupled barrels, it guarantees a 5-day power reserve, while its silicon balance spring ensures protection against magnetism and optimal precision, even in the most extreme conditions.
- The movement is visible through the sapphire caseback, finished according to the purest watchmaking tradition.
- Its 18-karat red-gold oscillating weight, featuring NAC treatment, reprises the characteristic design of the rotor from the 1953 model.
This new Fifty Fathoms in polished steel is not just a simple homage to an iconic watch; it is a diving watch that meets the demands of today’s collectors. With impeccable design, high performance, and breathtaking finish, it is ready to conquer divers worldwide.
