Blancpain is the oldest watchmaking company, dating back to 1735. The brand has weathered centuries and has a rich history of heritage, craftsmanship, and innovation. Credited with what we know as the modern dive watch, their now iconic Fifty-Fathoms just celebrated its 70th anniversary, having been released the same year as the Rolex Submariner in 1953. Although Blancpain might not be the first name to come to mind for many, the brand is seeing more deserved attention as collectors unpack their fantastic contribution to the world of horology.

The Blancpain Fifty Fathoms Tribute “No Radiations” is a thoughtful modern re-release and homage to one of BP's most historically important dive watches. Drawing inspiration from vintage military-issued Fifty Fathoms references, it preserves the defining design cues that made the original a legend among collectors and professional divers alike. Its deep black dial is accented by warm vintage-style lumed indices and the unmistakable “No Radiations” insignia — a historical marking used to signify the transition to safer luminous materials during the period. The longer lung length of the vintage models is simply too large on wrist and for anyone with medium sized wrists, the 40.3mm X 45mm feels much more ergonomic. With its unidirectional rotating bezel, sapphire display caseback, and 300 meters of water resistance, this watch is more than capable of everyday marine use. For collectors seeking a refined, high-grade dive watch that remains relatively under the radar, it stands out as one of our favorites and feels equally at home in seasoned collections or those just beginning to take shape.
