With the recent launch of Blancpain x Swatch collab it's worth revisiting the originating history of the Fifty Fathoms.

The Fifty Fathoms turns 70, and the Maison de Le Brassus will mark the occasion with due honors. But that's not all; it has also been 20 years since Marc Hayek breathed new life into the watch, restyling it to adapt to the changing times. Simultaneously, the new CEO, a passionate diver, founded the Blancpain Ocean Commitment, an internal initiative aimed at safeguarding the oceans. Additionally, a decade ago, Blancpain initiated a collaboration with the French biologist and underwater photographer Laurent Ballesta, funding his Gombessa expeditions. For Maison Blancpain, this marks a triple anniversary, and it will keep them engaged throughout the coming year. We already know that on January 3rd, the first Fifty Fathoms 70th Anniversary model will be unveiled. However, before that, let's take a moment to reflect on the history of the Fifty Fathoms, recognized as the archetype of the modern diving watch.

To be clear, this is a well-known story, and I won't be adding anything new here. Nevertheless, I believe it's worth revisiting to better understand the watch's value and to share it with those few who may not yet be familiar with it.

In 1952, the French Ministry of Defense commissioned Captain Robert Maloubier and Lieutenant Claude Riffaud to create an elite combat diver unit called the "Nageurs de Combat" (combat swimmers). Once the men were selected, the two officers also needed to provide suitable equipment. They searched all of Paris for suitable watches but failed to find anything on the market capable of withstanding the extreme conditions of underwater missions. Tests on available commercial watches were unsuccessful; they were all too small, unreadable underwater, and, above all, not waterproof.

They turned to Blancpain, then led by Betty Fiechter and her nephew Jean-Jacques. Jean-Jacques chose the name "Fifty Fathoms" for the watch developed by the Manufacture. A lover of both diving and literature, he drew inspiration from a passage in Shakespeare's famous work, "The Tempest." The passage reads, "Full fathom five thy father lies," from Ariel's Song (Act I, Scene II). The new watch was waterproof up to 50 fathoms (91.45 meters, to be precise), equivalent to 10 atmospheres. It was sufficiently large, protected from magnetic fields by a soft iron cage around the movement, highly legible even in the darkness of the depths thanks to the dark dial with luminescent markers. It featured a robust crown and a rotating bezel with a locking device, particularly useful during ascent.

Released in 1953, the Fifty Fathoms was adopted as the official watch of the French Navy and quickly gained a solid reputation for reliability and water resistance. It became an essential tool for divers, both military and civilian, spreading to special forces units in numerous countries, including the American Navy Seals (as well as German and Israeli units) and oceanographic exploration specialists (such as the Gers, Groupe d'Etudes et de Recherches Sous-marine d'Oltralpe). It even accompanied Jacques Cousteau and Louis Malle's team during the filming of "The Silent World," which won the Palme d'Or at the 1956 Cannes Film Festival and the Oscar for Best Documentary in 1957, becoming a milestone in underwater cinematography.

In recent time, watch magister Jose Pereztroika took a long, hard look at all the supporting material of the 1953 claims (which to be said it's to take a hedge on Rolex first diving watch). In his article there are clear evidence and comparison between the Blancpain Fifty Fathoms and the Rolex Submariner highlighting the extensive testing conducted on the Rolex Submariner by underwater photographer Dimitri Rebikoff in 1953, demonstrating Rolex's early commitment to dive watch technology and suggesting Blancpain flasy claimed 1953.

However, in the early 1980s, with the advent of the quartz crisis, the Fifty Fathoms went out of production and remained virtually off the radar until the early 2000s. Its acquisition by Jean-Claude Biver and Jacques Piguet in 1982 had led the brand to create more classic watches, staying true to the traditions of high watchmaking rather than focusing on technical instruments like the Fifty Fathoms. The Fifty Fathoms briefly returned to life in 1997 when the Maison came under the ownership of the current Swatch Group. It was then that the Blancpain Trilogy was born, consisting of a GMT, an aviation watch called the Air Command, and an updated Fifty Fathoms with increased water resistance of 30 atmospheres. However, the time was not yet right for the relaunch of the diving model, and it once again faded into obscurity for a few more years.

Until 2002, when Marc Hayek took the reins of Blancpain and discovered vintage Fifty Fathoms models in the Manufacture's vaults. He fell in love with them and tasked the Maison's technicians with developing a modern Fifty Fathoms. In 2003, for the watch's 50th anniversary, Blancpain presented a new model that combined the vintage aesthetics with the water resistance of the 1997 version, adding a bezel with a curved, scratch-resistant sapphire insert. The presence of this element speaks volumes about the Maison's commitment to exploring new materials and innovations, a tradition carried forward since the Swatch Group era. The 150 limited edition pieces sold out quickly, leading to the decision to resume production.

In 2007, Blancpain launched a new trilogy of watches that laid the foundation for the collection still in the catalog today. The first was the Fifty Fathoms Automatique, similar in aesthetics and spirit to the original model but featuring a new in-house movement, the Caliber 1315. Derived from the manually wound Caliber 13R0 from 2006, it stood out for its three barrels, providing a power reserve of 5 days. The second was the Fifty Fathoms Chronographe Flyback, equipped with waterproof pushers designed to activate the chronograph underwater. Finally, the Fifty Fathoms Tourbillon, certainly the least suitable for diving but created for celebratory purposes. Equipped with a flying tourbillon and a sapphire crystal case back, yet still waterproof up to 30 atmospheres, it was a testament to the Maison's craftsmanship.

Since then, over the past 15 years, the Fifty Fathoms' story has continued with a wide range of variations in terms of materials, sizes, complications, and straps. Consider the revival of the Bathyscaphe, also created in the late 1950s by Jean-Jacques Fiechter and reissued in 2013 for its 60th anniversary, or the feminine versions. It's a story that Blancpain is still writing, day by day.

On September 9th, with the Blancpain x Swatch Scuba Fifty Fathoms, or a new chapter has been written in these long legacy legendary watch.
