Blancpain Fifty Fathoms 5015 titanium specifications
The two blue titanium references share the core specification. Their main practical difference in Blancpain’s US listings is the included strap or bracelet, which is reflected in the displayed price.

What changes between the O52B and 98B?
5015 12B40 O52B: sail-canvas strap
The O52B is the lower-priced of these two listed configurations and comes with a sail-canvas strap and folding clasp. Blancpain’s product listing also identifies NATO and sail-canvas strap options; confirm the exact fastening and included configuration with Blancpain or a point of sale.

The 98B pairs the same blue dial and titanium case with a satin-brushed titanium bracelet and folding clasp. Blancpain’s US listing displayed it at $1,500 more than the O52B on October 8, 2026. That difference compares the displayed prices of these specific listings; it is not a general price premium for every strap or bracelet option.
Case size, movement and water resistance
Both listed versions have a 45 mm titanium case and automatic Caliber 1315. Blancpain states a 120-hour power reserve on its current US product pages. That is the manufacturer’s specification, not an independently measured running-time result.
Blancpain’s 2020 collection technical PDF gives the 45 mm titanium Automatique a water-resistance rating of 30 bar, approximately 300 meters. This is the manufacturer’s published rating, not a hands-on test result. Consult Blancpain’s current guidance for care, servicing and appropriate use.
