Blancpain Watch Straps
Dive-ready straps for the Blancpain Fifty Fathoms and Bathyscaphe. Our high-grade FKM rubber straps shrug off salt water, sun and sweat, while leather and canvas options add versatility on dry land. Every strap is cut to the exact width these cases demand, with a secure buckle for the sporty, functional Fifty Fathoms look.
Fitment by model
Fifty Fathoms 45mm – 23mm
Fifty Fathoms Bathyscaphe 43mm – 23mm
Smaller Fifty Fathoms and Barakuda-style cases – 20mm
23mm is an unusual width, so a standard 22mm or 24mm strap won’t fit properly – measure between the lugs if you’re unsure.
Which strap for which use?
FKM rubber is the natural partner for a dive watch: waterproof, comfortable and resistant to UV and salt water. Leather or canvas dresses the Fifty Fathoms down for the office or weekend.
Frequently asked questions
What size strap does a Fifty Fathoms take? The 45mm Fifty Fathoms and 43mm Bathyscaphe take 23mm.
Is FKM better than silicone for a dive watch? Yes – it’s denser, keeps its shape and resists salt water and sunscreen far better.
Can I fit it myself? Yes – with a spring bar tool the swap takes a few minutes.
