Blancpain Fifty Fathoms 5015-12B30-B52B

The Blancpain Fifty Fathoms Automatique, reference 5015-12B30-B52B, is a modern iteration of the brand’s iconic dive watch, presented in a lightweight satin-brushed titanium case. The watch head itself is identical to the 5015-12B30-B52A, sharing the same 45mm case, black sunray dial, sapphire bezel, and high-performance Caliber 1315 movement with a 120-hour power reserve. The significance of this specific reference code lies in the suffix “B52B”, which designates a different strap and buckle combination. While the “B52A” comes on a sailcloth strap with a traditional titanium pin buckle, the “B52B” is delivered on a black sailcloth strap that is fitted with a titanium deployant (folding) clasp. This variation offers a more secure and upscale alternative to the standard pin buckle, appealing to clients who prefer the convenience and streamlined look of a deployant clasp. This seemingly minor detail is an important distinction in the luxury watch market, providing choice and catering to specific customer preferences for wearability and style.
