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

The lug width of the Breitling Transocean A1931012/BB68/106W/A20BA.1 is 22mm. This measurement is taken between the two lugs at the point where the strap attaches to the case, and should be measured precisely using a millimetre calliper for an accurate fit.

For the Transocean, a polished alligator strap in black or midnight blue pairs exceptionally well with the formal character of the silvered dial. Alternatively, a Tuscan vegetable-tanned calf leather strap in cognac or honey tones develops a natural patina over time that complements the vintage aesthetic of the piece. Both options require a 22mm lug width with a straight or lightly curved tang.

The strap on the Transocean is removed using a fine-tipped or forked spring bar tool, inserted into the lateral slot of the spring bar between the lugs. Compress the spring bar on one side, slide out the old strap, and fit the new one by aligning the strap keeper holes with the lugs. No professional tools are required, though it is advisable to work on a soft surface to protect the case finish.

Yes, there is a wide selection of quality aftermarket straps available in the 22mm format for this Transocean. Milano Straps produces handcrafted straps in alligator leather, vegetable-tanned calf, shell cordovan and other materials, all with a 22mm lug width and available in various lengths to suit different wrist circumferences. These are not Breitling original straps but are crafted to a high standard of materials and finish.

The lifespan of a leather strap depends on the type of leather and daily wear conditions. A vegetable-tanned calf strap used daily typically lasts between 12 and 24 months before replacement is needed. High-quality alligator leather can last 3 to 4 years with proper care (avoid prolonged exposure to water; condition periodically with a neutral cream). Milano Straps provides an 18-month manufacturing defect warranty on all its straps.
