Commentary
The novelty is not a new model. The Fifty Fathoms Automatique 42 has existed in titanium case as well as in a rose gold case in 2024.
The series was the followup to the success of Act 1, which was the first time the Fifty Fathoms Automatique was released in 42mm. Act 1 had a steel case, but is a limited edition of three series of 70 watches and reserved for EMEA, Asia-Pacific and the Americas via pre-orders. All 210 watches are already sold. It also had a special platinum oscillating mass.

All else remain the same, including the polished steel case. This new reference will be in Blancpain’s permanent collection and not limited.

The movement remains the capable caliber 1315, with 5 day power reserve, but this time sans the platinum rotor.
Release details
The Legacy of the Celebrated Fifty Fathoms of 1953
In 1953, Blancpain presented the first modern diving watch, the Fifty Fathoms. As the first true watch designed for professional divers, it was immediately adopted by pioneers of underwater diving and elite marine corps worldwide. Designed to withstand the most extreme conditions, it was equipped with:
- 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 feet or 91.44 meters)
A true icon of performance meeting the vital requirements of underwater diving. Today, the Fifty Fathoms embodies the perfect union between timeless design and uncompromising technology.

A New Release in Polished Steel
Launched in 2024, the 42 mm version seduces with its 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 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, while 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 pin buckle or deployant clasp.

At the heart of this Fifty Fathoms is caliber 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. Visible through the sapphire case back, the movement, finished according to the purest watchmaking tradition, with its 18-carat red gold oscillating weight featuring NAC treatment, reprises the characteristic design of the rotor of the 1953 model.
The Unmatched Blancpain Caliber 1315

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. Impeccable design, high-flying performance, and breathtaking finish: ready to conquer divers worldwide.
