Strap for Transocean Chronograph Unitime Stainless Steel / Silver / Croco

The lug width of the Breitling Transocean AB0510U0.A790.760P. is 24mm. This measurement refers to the internal distance between the two lugs of the case, best verified with a millimetre calliper positioned at the strap attachment point. All 24mm straps with a straight or slightly curved end are compatible with this reference.

For the Transocean 46mm, a vegetable-tanned alligator strap with contrast stitching is the most coherent choice given the model's identity. Shell cordovan offers a technically superior alternative in terms of durability and patina development. For more active contexts, a grained or embossed calf leather strap maintains the instrument-grade legibility of the watch without sacrificing elegance.

The strap is removed by acting on the spring bars with a dedicated flat-tip or forked springbar tool, inserted into the lug hole to compress the spring bar. Care should be taken to avoid scratching the case — placing a soft cloth between the tool and the steel is recommended. The new 24mm strap is fitted by compressing the spring bars and snapping them into the lug recesses.

Yes, the aftermarket offers a wide range of 24mm straps fully compatible with the Breitling Transocean 46mm. MilanoStraps provides handcrafted options in alligator, calf leather and shell cordovan with 24mm attachment, available with stainless steel buckle or deployant clasp. Italian artisan quality ensures precise dimensional tolerances and finishes on a par with the original.

The lifespan of a leather strap depends on the material and frequency of use. A quality vegetable-tanned alligator strap, maintained with periodic conditioning cream, can last between 3 and 5 years with regular daily wear. Shell cordovan tends to last longer due to the density of its fibres. Exposure to perspiration, moisture and chemical agents is the primary cause of deterioration. Casati Milano's guarantee covers manufacturing defects for 18 months.
