Strap for Colt Lady Diamond / Pearl / Sahara / Pin

The Breitling Colt A7738853/A770/238X/A14BA.1 has a lug width of 16mm. This is the internal measurement between the two case lugs on the 33mm case, which should be verified with a digital calliper before purchasing any replacement strap.

The most balanced options for the Colt 33mm are Tuscan vegetable-tanned calfskin for daily wear — it develops a natural patina over time — and alligator leather for formal occasions. A technical nylon NATO strap is ideal for sport use, keeping the visual proportions suited to the compact 33mm case.

The strap is replaced by operating on the spring bars that connect it to the case lugs. A spring bar tool with a fine 1mm tip is required. Gently lever on the inner side of the lug, compress the spring bar and slide the strap out. The operation takes approximately two minutes and requires no professional equipment.

Yes. Any strap with a 16mm attachment is technically compatible with the Colt 33mm. Milano Straps offers a selection of handcrafted straps in 16mm — in leather, alligator, NATO and rubber — made with replacement spring bars included and fittings calibrated for this specific width.

A quality leather strap used daily typically lasts between 18 and 36 months, depending on care and conditions of use. Prolonged contact with water, perspiration or perfume accelerates deterioration. Milano Straps vegetable-tanned leather straps are covered by an 18-month guarantee against manufacturing defects.
