Strap for Transocean Date Stainless Steel / Silver / Croco / Pin

The lug width of the Breitling Transocean A1036012/G721/737P/A20BA.1 is 22mm. This measurement refers to the gap between the case lugs and is the essential parameter when selecting a compatible strap. To verify it on your own piece, use a digital calliper positioned perpendicularly between the two upper lugs.

Given the Transocean's urbane and formal character, the most fitting materials are Tuscan vegetable-tanned calfskin and Louiseville alligator leather. Vegetable-tanned calf develops a distinguished patina over time, whilst alligator adds a layer of formal refinement. For sportier wear or humid conditions, vulcanised rubber maintains its shape and aesthetic without compromise.

Strap replacement requires a spring bar tool (fork-tip). Insert the tip into the notch between the lug and the strap, compress the spring bar, and slide the strap free. Care must be taken not to scratch the lug surfaces. If you are unfamiliar with the procedure, it is advisable to consult a watchmaker or a specialist atelier.

Yes. Any strap with a 22mm attachment width is technically compatible with the Breitling Transocean A1036012/G721/737P/A20BA.1. Milano Straps offers a curated selection of Italian handcrafted straps in calf, alligator, NATO, and rubber, all fitted with standard spring bars and compatible with both the original Breitling buckle and aftermarket stainless steel hardware.

Longevity depends on the material and frequency of wear. A quality vegetable-tanned calf strap, properly conditioned and kept away from excessive moisture, will typically last 2–4 years. Alligator, being denser and more resilient, can exceed 4–5 years. Milano Straps provides an 18-month guarantee against manufacturing defects on all straps.
