Strap for Transocean Chronograph Stainless Steel / Black / Croco / Folding

The lug width of the Breitling Transocean AB015212/BA99/738P/A20D.1 is 22mm. This measurement should be taken directly between the case lugs using a digital calliper or a millimetre ruler. Respecting this dimension is essential to ensure a precise fit and a proportionate appearance on the wrist.

For the Transocean with its 43mm stainless steel case, straps in vegetable-tanned alligator or box calf leather are the most coherent choices given the model's sartorial aesthetic. Shell cordovan is recommended for those seeking a compact, long-lasting surface. In all cases, the 22mm lug width is the key parameter when selecting a replacement strap.

The strap on the Transocean is secured by standard 22mm spring bars. To replace it, use a fine-tipped spring bar tool: compress the spring bar, slide the strap out from the lug, and insert the new one. The operation takes approximately two minutes and requires no case opening or specialist tools.

Yes, any strap with a 22mm lug width and standard spring bars is compatible with the Transocean AB015212/BA99/738P/A20D.1. Milano Straps offers a selection of handcrafted leather straps made to measure from carefully selected materials, which pair seamlessly with the stainless steel case of the Transocean without the need for any adapters.

The lifespan of a leather strap depends on the material, tanning method, and daily care. A high-quality alligator or box calf strap that has been vegetable-tanned, kept away from prolonged moisture, and treated periodically with a neutral conditioner can last between 3 and 7 years whilst retaining its shape and developing a natural patina. Milano Straps provides an 18-month warranty against manufacturing defects on all its straps.
