Strap for Transocean Chronograph Red Gold / Diamond / Black / Croco

The Breitling Transocean RB015253.BB16.739P has a lug width of 22mm. This measurement refers to the internal distance between the two lugs where the strap is fitted. Before purchasing an aftermarket strap, it is advisable to verify the measurement directly on your case using a digital calliper.

For an 18kt red gold case such as that of the Transocean RB015253.BB16.739P, vegetable-tanned alligator straps in cognac, bordeaux or tobacco brown tones offer the greatest aesthetic coherence. The patina that alligator develops over time complements the warm reflections of red gold beautifully. For sporting use, a 22mm vulcanised rubber strap is the most technically resilient option.

Strap replacement on the Transocean requires a double-ended spring bar tool to remove the 22mm spring bars housed within the lugs. Gently lever against the end of the spring bar to compress the spring, extract the original strap, then fit the new strap by seating one end of the spring bar into the lug first before compressing and seating the other. This can be carried out independently with the correct tools.

Yes. Any strap with a 22mm attachment width and standard spring bars is compatible with the Transocean RB015253.BB16.739P. Milano Straps offers a selection of handcrafted 22mm straps in alligator, Tuscan calf, shell cordovan and rubber, all produced by hand with progressive tapering towards the buckle for maximum wrist comfort.

The lifespan of a leather strap depends on the hide, the tanning method and the care taken. A vegetable-tanned alligator strap, kept away from excess water and perspiration and treated periodically with nourishing cream, can last between 3 and 7 years whilst retaining full structural integrity. Calf leather typically lasts 2–4 years. Shell cordovan, owing to the density of the fibres in the horse's shell, is the most durable leather of all.
