Breitling
Colt A7438953.BD82.213X— lug 18mm

The Breitling Colt A7438953.BD82.213X has a lug width of 18mm. To confirm this on your specific piece, use a digital calliper to measure the internal gap between the two lugs, keeping the measurement parallel to the bezel.

For the Colt 36mm, the most balanced choice is a vegetable-tanned calf leather strap with a smooth grain or a flat-scale Mississippiensis alligator. Both respect the restrained aesthetic of the dial and complement the brushed steel case without overwhelming the 36mm proportions.

The strap is removed using a fine-tipped springbar tool inserted into the internal channel of the lug. The Colt 36mm typically uses standard 1.5mm diameter springbars. The procedure takes approximately two minutes and does not require professional tools if you are familiar with the mechanism.

Yes. Any 18mm strap with a standard springbar attachment is compatible. Milano Straps offers a curated selection of handcrafted 18mm straps in calf leather, alligator, shell cordovan and vulcanised rubber, available with buckle or deployant clasp.

A quality leather strap — vegetable-tanned calf or dressed alligator — used daily has an average lifespan of 18 to 36 months, depending on exposure to perspiration and humidity. Conditioning with a specialist fine leather cream every three to four months significantly extends the strap's life and preserves its patina.
