Strap for Transocean Chronograph Unitime Stainless Steel / Black / Croco

The lug width of the Breitling Transocean AB0510U4.BB62.760P is 24 mm. This is a generous measurement, consistent with the 46 mm case diameter, and relatively uncommon in contemporary watchmaking. Before purchasing an aftermarket strap, it is always advisable to verify the lug width directly on the case using a calliper.

For the Transocean with a 24 mm lug width, the most suitable straps are alligator belly or hornback for formal occasions, vegetable-tanned calf leather for everyday wear with a developing patina over time, and vulcanised rubber for sporting use. A deployant clasp in polished steel is the closure that best respects the original proportions of the watch.

The strap on the Breitling Transocean is replaced using a spring bar tool to remove the spring bars securing the strap to the case lugs. Care should be taken to avoid scratching the steel case: it is advisable to use plastic or felt protectors on the tool. Alternatively, any watchmaker or specialist atelier can perform the swap in a matter of minutes.

Yes, any strap with a 24 mm lug width and standard spring bars is compatible with the Breitling Transocean AB0510U4.BB62.760P. Milano Straps offers a selection of handcrafted 24 mm straps in various materials and finishes, available either made to order or ready to purchase online, all compatible with this reference.

The lifespan of a leather strap depends on the quality of the hide, care, and frequency of use. A quality vegetable-tanned calf leather strap worn daily and kept away from excessive moisture and perspiration can last between 18 and 36 months. A top-grade alligator strap, worn on rotation, can exceed 3 to 5 years. Milano Straps provides an 18-month guarantee against manufacturing defects on all Casati Milano straps.
