Strap for Transocean Chronograph 1461 Stainless Steel / Silver / Military / Pin

The lug width of the Breitling Transocean A1931012/G750/106W/A20BA.1 is 22mm. This measurement is taken with a calliper at the internal attachment point between the two lugs, and is determined by the 43mm case diameter and the proportions chosen by Breitling for this reference.

For this Transocean, alligator leather in black or tobacco brown is the most coherent choice, reflecting the movement's complexity and the formal character of the case. Alternatively, vegetable-tanned calf develops an authentic patina over time, while shell cordovan provides a compact surface and dry lustre that complements brushed steel. For sport use or humid environments, a quality rubber strap is recommended.

The strap is removed using a fine-tipped or lever-type spring bar tool inserted into the dedicated notch on the side of the lug. The 22mm spring bar is compressed and slides out of its seat. Care should be taken to avoid scratching the lugs: rest the watch on a soft cloth and use dedicated watchmaking tools throughout the operation.

Yes. Any strap with a 22mm attachment width and standard spring bars is compatible with this Breitling reference. Milanostraps.it offers a curated selection of 22mm straps in various materials — leather, rubber, NATO — handcrafted to ensure a precise fit on the Transocean's original lugs.

Longevity depends on the material and conditions of use. A quality alligator strap worn daily typically lasts 18–36 months. Vegetable-tanned calf, being more porous, tends to deteriorate faster with frequent perspiration. Shell cordovan, owing to its dense fibre structure, is the most durable of natural leathers. Keeping the strap away from prolonged moisture and applying a suitable conditioner periodically will significantly extend its service life.
