Its original tool-watch design and robust build have been reinterpreted in multiple sizes, materials, and complications that have helped establish the Fifty Fathoms as an undisputed luxury object. This contemporary collection has largely been built upon several key models in the Fifty Fathoms\u2019 half-century-plus of history (albeit a history once interrupted, and nearly totally derailed, by the 1970s-\u201980s Quartz Crisis). Here we showcase the five most important vintage Blancpain Fifty Fathoms watches and examine how some of them have been reworked for the modern era.<b id=\"docs-internal-guid-79669482-7fff-efd2-2148-e8815c1cbd08\"><span> <\/span><\/b><\/p>\n<p><meta charset=\"utf-8\"\/><meta charset=\"utf-8\"\/><b id=\"docs-internal-guid-f5353e5d-7fff-22eb-d60a-ce306a59f4a9\"><span><\/p>\n<p><h2>Original Blancpain Fifty Fathoms (1953)<\/h2>\n<\/p>\n<p><\/span><\/b><\/p>\n<div style=\"text-align: left;\"><img decoding=\"async\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0278\/9723\/3501\/files\/Blancpain-FF-1953-2.jpg?v=1654264148\" alt=\"vintage blancpain fifty fathoms\" style=\"margin-bottom: 16px; float: none;\"\/><\/div>\n<p dir=\"ltr\"><meta charset=\"utf-8\"\/><meta charset=\"utf-8\"\/>Of course, it is the very first Fifty Fathoms, from the seminal year of 1953, that remains the most historic and impactful in terms of design. Its genesis began with then-Blancpain CEO Jean-Jacques Fiechter, an avid diving enthusiast who had long wanted to develop a watch that would be ideal for his hobby. He got the chance when Captain Robert Maloubier, a French naval officer, approached Blancpain to design a reliable, mission-ready timepiece suitable for elite naval divers to wear. The watch that emerged, designed with the input of Maloubier and his team members, was a true original: Its 42mm steel case (exceptionally large for the time) water-resistant to 91.45 meters, or 50 fathoms, the maximum depth recommended for scuba divers. Its dial was black and its numerals were luminescent for greater legibility underwater. It was the first divers\u2019 watch with a self-winding movement, the first with an antimagnetic case, and the first to employ the patented, double-sealed crown that Fiechter had developed.<\/p>\n<div style=\"text-align: left;\"><img decoding=\"async\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0278\/9723\/3501\/files\/Blancpain-FF-original-1953-CU-2.jpg?v=1654265167\" alt=\"vintage blancpain fifty fathoms\" style=\"float: none;\"\/><\/div>\n<p dir=\"ltr\"><meta charset=\"utf-8\"\/><meta charset=\"utf-8\"\/>Most notably, the Fifty Fathoms was the first watch to include a lockable bezel with a dive-time scale that rotated in only one direction. (Other early, influential genre pioneers, like the Rolex Submariner that emerged around the same time, still had bidirectional bezels.) This practical and potentially life-saving innovation prevented a diver from accidentally jarring the bezel in the wrong direction for an inaccurate reading of how much time he\u2019d spent underwater and thus miscalculating how much oxygen he had left in the tank. The first Fifty Fathoms (which had no official reference number but was identified by its movement as Ref. 2642) was famously worn by Jacques Cousteau in his award-winning undersea documentary, The Silent World, and some of the earliest models were even co-branded as \u201cAqua-Lung\u201d editions courtesy of the relationship between Blancpain and the scuba-gear brand founded by Cousteau and his partner Emile Gagnan.<\/p>\n<p dir=\"ltr\"><meta charset=\"utf-8\"\/><meta charset=\"utf-8\"\/><b id=\"docs-internal-guid-f5353e5d-7fff-22eb-d60a-ce306a59f4a9\"><span><\/p>\n<p><h2>Blancpain Fifty Fathoms MIL-SPEC (1957)<\/h2>\n<\/p>\n<p><\/span><\/b><\/p>\n<div style=\"text-align: left;\"><img decoding=\"async\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0278\/9723\/3501\/files\/Blancpain-FF-Mil-Spec-vintage-Sothebys-2.jpg?v=1793993399\" alt=\"vintage blancpain fifty fathoms\" style=\"margin-bottom: 16px; float: none;\"\/><\/div>\n<p dir=\"ltr\"><em><strong>Photo: Sotheby&#8217;s<\/strong><\/em><\/p>\n<p dir=\"ltr\"><span>In 1957, Blancpain updated the design of the Fifty Fathoms at the behest of a new military client, the U.S. Navy, and for this version, Jean-Jacques Fiechter added yet another layer of underwater functionality. These watches, now exceedingly rare, added <\/span><span>a \u201cwater-tightness indicator\u201d on the dial, a small round disk whose color changed from white to red in its upper half if it was exposed to water or humidity \u2014 a failsafe measure to alert a wearer in the event that any moisture had penetrated the case. This indicator became a standard feature on dive watches contracted by U.S. military units, leading to the MIL-SPEC 2 standard for subsequent naval dive watches.<\/span><\/p>\n<div style=\"text-align: left;\"><img decoding=\"async\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0278\/9723\/3501\/files\/Blancpain-Fifty-Fathoms-Mil-Spec-2.jpg?v=1727365639\" alt=\"vintage blancpain fifty fathoms\" style=\"margin-bottom: 16px; float: none;\"\/><\/div>\n<p dir=\"ltr\"><span>The original 1957 MIL-SPEC editions were sized around 41mm in stainless steel, with a thickness around 13mm and a plexiglass crystal over the dial. Inside the case was the \u201cRotomatic\u201d Caliber R.570, with 17 jewels and Incabloc shock protection, protected from magnetic fields inside a soft-iron dust-cover caseback. For the 60th anniversary of this landmark release, in 2017, Blancpain launched the \u201cTribute to MIL-SPEC\u201d edition of the modern Fifty Fathoms (above), around the same dimensions as the originals, with modern upgrades like a sapphire insert for the dive-scale bezel and the in-house automatic Caliber 1151.<\/span><\/p>\n<p dir=\"ltr\"><span><meta charset=\"utf-8\"\/> <meta charset=\"utf-8\"\/> <b id=\"docs-internal-guid-f5353e5d-7fff-22eb-d60a-ce306a59f4a9\"><\/p>\n<p><h2>Blancpain Fifty Fathoms Bund &#8216;No Rad&#8217; (1960s)<\/h2>\n<\/p>\n<p><\/b><\/span><\/p>\n<div style=\"text-align: left;\"><img decoding=\"async\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0278\/9723\/3501\/files\/Blancpain-FF-No-Rad-vintage-Sothebys-2.jpg?v=1793994222\" alt=\"vintage blancpain fifty fathoms\" style=\"margin-bottom: 16px; float: none;\"\/><\/div>\n<p dir=\"ltr\">\u00a0<\/p>\n<p dir=\"ltr\"><em><strong>Photo: Sotheby&#8217;s<\/strong><\/em><\/p>\n<p dir=\"ltr\"><meta charset=\"utf-8\"\/><meta charset=\"utf-8\"\/>The Fifty Fathoms proved popular enough with navy divers in France and the U.S.A. that other nations got in line to order the watches for their own elite underwater combat teams. One was Germany\u2019s Bundeswehr (armed forces), which ordered a very specific, now-collectible version of the Fifty Fathoms for its Kampfschwimmer commando units in 1960. The watch\u2019s dial was a variation on those developed for the MIL-SPEC editions adopted by the U.S. navy: instead of the moisture-indicating disk at 6 o\u2019clock, the so-called \u201cNo Radiations\u201d or \u201cNo-Rad\u201d Fifty Fathoms had a colorful red-and-yellow trefoil badge at the same position. The badge was a universal, visual shorthand that assured the watch\u2019s wearer that its dial was not treated with potentially dangerous radioactive luminous paints (such as Radium and Promethium) that earlier military tool watches had adopted. It touted as a virtue the watch\u2019s adherence to the military\u2019s \u201cT&lt;25\u201d mandate that the dial\u2019s lume carried less than 25 millicures of Tritium, the milder radioactive isotope that superseded the ones mentioned above. Blancpain even added a small \u201cT&lt;25\u201d notation on the dial, under the 5 o\u2019clock position on the minute track.<\/p>\n<div style=\"text-align: left;\"><img decoding=\"async\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0278\/9723\/3501\/files\/Blancpain-FF-No-Rad-2_37774474-db25-4cb6-8fad-b9cdc5c1f203.jpg?v=1665499133\" alt=\"vintage blancpain fifty fathoms\" style=\"float: none;\"\/><\/div>\n<p dir=\"ltr\"><meta charset=\"utf-8\"\/><meta charset=\"utf-8\"\/>The watches had a self-winding A. Schild 1700 movement, behind a screwed caseback engraved with \u201cBUNDESWEHR\u201d and a 12-digit NATO stock number. Some of the most desirable models for collectors are mounted on Bund straps, named for their origins in German military watch design, notable for their protective leather pad under the main strap that cushions the watch case and shields the wearer\u2019s wrist from extreme heat or cold. In 2021, Blancpain issued a limited re-edition of the No-Rad model (above), sized at a period-appropriate 40.3mm in diameter and containing Blancpain\u2019s ultra-thin, in-house Caliber 1151, which provides a four-day power reserve that the watch\u2019s original wearers would have envied.<\/p>\n<p dir=\"ltr\"><meta charset=\"utf-8\"\/><meta charset=\"utf-8\"\/><b id=\"docs-internal-guid-f5353e5d-7fff-22eb-d60a-ce306a59f4a9\"><span><\/p>\n<p><h2>Blancpain\/Tornek-Rayville TR-900 (1963)<\/h2>\n<\/p>\n<p><\/span><\/b><\/p>\n<div style=\"text-align: left;\"><img decoding=\"async\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0278\/9723\/3501\/files\/Tornek-Rayville-vintage-front-Sothebys-2.jpg?v=1763397798\" alt=\"vintage blancpain fifty fathoms\" style=\"margin-bottom: 16px; float: none;\"\/><\/div>\n<p dir=\"ltr\"><em><strong>Photo: Sotheby&#8217;s<\/strong><\/em><\/p>\n<p dir=\"ltr\"><span>One of the most important historical versions of the Fifty Fathoms had an entirely different brand name, and model name, on the dial. The convoluted backstory of the\u00a0<\/span><span>Tornek-Rayville TR 900 watch, worn by U.S. Navy divers on recon missions during the Vietnam War, is more thoroughly detailed in <\/span><a href=\"https:\/\/teddybaldassarre.com\/blogs\/watches\/tornek-rayville-review\"><span>this article<\/span><\/a><span>, but to summarize: Blancpain sought to secure itself a lucrative U.S. military contract during the 1960s, but \u201cBuy American\u201d laws at the time disqualified the company as a supplier, even though it had supplied Fifty Fathoms watches to American clients previously. A Blancpain distributor named Allen Tornek hit upon the idea of rebranding the Blancpain watches under the name \u201cTornek-Rayville\u201d (his surname plus a phonetic anagram of \u201cVilleret,\u201d where Blancpain was headquartered) and adding just enough American parts to qualify under the law. Made from 1964 to 1966, and distinguished by the dials\u2019 moisture indicator disk adopted from the earlier MIL-SPEC editions (along with luminous elements made from a mildly radioactive substance called Promethium-147, which led the military to dispose of many of them after they were returned from service members), these watches are extremely rare today. Military history buffs will note that Blancpain Tornek-Rayville watches, equipped with the automatic Caliber AS 1361, were worn by the U.S. Navy\u2019s UDT (Underwater Demolition Team), the precursor of today\u2019s Navy SEALs.\u00a0<\/span><b\/><\/p>\n<div style=\"text-align: left;\"><img decoding=\"async\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0278\/9723\/3501\/files\/Tornek-Rayville-TR-660-2.jpg?v=1763398763\" alt=\"vintage blancpain fifty fathoms\" style=\"margin-bottom: 16px; float: none;\"\/><\/div>\n<p dir=\"ltr\"><span>The \u201cTornek Rayville\u201d branding, which<\/span><a href=\"https:\/\/blancpain.com\"><span> Blancpain<\/span><\/a><span> abandoned back in the 1960s, has made a comeback courtesy of watch entrepreneur Bill Yao, who had previously founded the tool-watch brand MKII. In 2010, Yao acquired the brand name and launched the new version of Tornek-Rayville \u2014 unconnected to Blancpain and with a heavy emphasis on a reissued version of the most legendary model, the aforementioned TR-900, which the brand has dubbed the TR-660 (above).<\/span><\/p>\n<p dir=\"ltr\"><span><meta charset=\"utf-8\"\/> <meta charset=\"utf-8\"\/> <b id=\"docs-internal-guid-f5353e5d-7fff-22eb-d60a-ce306a59f4a9\"><\/p>\n<p><h2>Blancpain Fifty Fathoms Bathyscaphe (1956)<\/h2>\n<\/p>\n<p><\/b><\/span><\/p>\n<div style=\"text-align: left;\"><img decoding=\"async\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0278\/9723\/3501\/files\/Blancpain-FF-Bathyscaphe-Vintage-1968-2.jpg?v=1793995029\" alt=\"vintage blancpain fifty fathoms\" style=\"margin-bottom: 16px; float: none;\"\/><\/div>\n<p dir=\"ltr\"><span>Three years after the Fifty Fathoms debuted, predominantly targeted at military and professional customers, Fiechter turned his company\u2019s attention to a civilian-targeted model, the Fifty Fathoms Bathyscaphe, which debuted in 1956. The watch took its name from the legendary undersea vehicle invented by Swiss oceanographer Jacques Piccard, which launched in 1953, the same year as the original Fifty Fathoms watch. The Bathyscape edition offered a more streamlined, stylish, \u201cskin diver\u201d aesthetic than its tool-oriented predecessor, with a steel case that came in at a modest 34.5mm in diameter, with straighter lugs and a slimmer profile. Its dial was more minimalist, in black or sunburst gray, with distinctive blocky hands, geometric hour markers, and (on the earliest models) a prominent numeral 12. Its Bakelite bezel was also cleaner and simpler, minus the glossy finish of the original\u2019s. The movement inside the first generation was an automatic A. Schild caliber, though later iterations like the MC4 models also used manually wound mechanical movements like the AS 1187.\u00a0<\/span><\/p>\n<div style=\"text-align: left;\"><img decoding=\"async\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0278\/9723\/3501\/files\/Blancpain-FiftyFathoms-Bathyscaphe-38-2_f5854fec-81b8-4f35-abe8-5ad502708b53.jpg?v=1690552209\" alt=\"vintage blancpain fifty fathoms\" style=\"margin-bottom: 16px; float: none;\"\/><\/div>\n<p dir=\"ltr\"><span>In 2013, the Bathyscaphe made its triumphant return as not only a vintage-inspired tribute piece but as the foundation for an entire subfamily of the Fifty Fathoms, today encompassing multiple materials and complications. The core three-handed models (as above), which took direct inspiration from models of the 1960s, debuted in 43mm and 38mm cases. They have the same distinctive handset as their predecessors, along with a 4:30 date window, simple geometric hour markers, and a luminous orientation dot on the bezel. Further cementing the modern Bathyscaphe as a 21st-century timepiece is its bezel\u2019s use of Liquidmetal, an amorphous metal alloy that bonds with the ceramic insert to enhance its scratch resistance; and the in-house Blancpain Caliber 1315, which brings a 120-hour power reserve to the table.<\/span><\/p>\n<\/div>\n\n","protected":false},"excerpt":{"rendered":"<p>The Blancpain Fifty Fathoms, revered as one of the first and most influential modern divers\u2019 watches, is today the cornerstone of Blancpain\u2019s collection.
