Strap for Transocean Chronograph Unitime Stainless Steel / Silver / Rubber

The lug width of the Breitling Transocean AB0510U0.A790.267S is 24mm. This width is standard for the model and is determined by the proportions of the 46mm case. Always measure the interior of the lugs: the correct distance must be exactly 24mm to ensure proper strap insertion.

For the Transocean AB0510U0.A790.267S, premium alligator (Grade A or Porosus) represents the finest choice: its natural parallel grain amplifies sophistication without competing visually with the stainless steel case. Alternatively, vegetable-tanned calf offers positive ageing and soft patina development over time. For dynamic use, vintage-texture rubber or a heavy cordura NATO remain stylistically coherent with the model's aviation heritage.

Strap change on the Transocean is performed via the visible attachment pins in the lugs. Using an appropriate tool (spring bar tool) or a thin flat-head screwdriver, apply pressure to one side of the pin until the spring-loaded end retracts, allowing the lug to be extracted from its seat. Insert the new strap into the opposite lug, then allow the pin to snap back into its original position. Perform the same operation on the opposite side.

Before purchase, we recommend confirming precise measurements via WhatsApp with the Casati Milano atelier.

A premium leather strap (Grade A alligator or vegetable-tanned calf) typically lasts 5-7 years with daily use, with potential extension to 10 years with regular maintenance (monthly cleaning, six-monthly conditioning). The patina that develops over time is a sign of authentic ageing, not deterioration. Milano Straps guarantees 18 months on all bespoke straps crafted by the Casati Milano atelier and offers regeneration and conditioning services to extend leather lifespan.
