Strap for Colt Quartz Stratus Silver / Calf / Pin

The lug width of the Breitling Colt A7438811/G792/433X/A20BA.1 is 22 mm. This dimension is consistent across the entire Colt 44 mm range and ensures broad compatibility with aftermarket straps available in this size.

The ideal choice depends on the intended use. For a formal register, a vegetable-tanned calfskin or smooth alligator strap works best. For sport or field use, a nylon NATO or vulcanised rubber strap provides durability and moisture resistance. In all cases, the correct lug width is 22 mm.

To replace the strap, use a fine-tipped spring bar tool. Insert the tip into the lug slot, compress the spring bar and slide the strap free. The process is non-invasive and requires no professional tools, though working on a soft pad is advisable to prevent scratching the case.

Yes. Any strap fitted with standard 22 mm spring bars is compatible with the Colt A7438811/G792/433X/A20BA.1. Milanostraps.it offers a curated range of handcrafted leather, rubber and nylon straps in this size, typically tapering to 20 mm at the buckle end.

A quality vegetable-tanned leather strap used daily typically lasts between 12 and 24 months, depending on exposure to perspiration, humidity and heat. Casati Milano straps carry an 18-month guarantee against manufacturing defects. Alternating between two straps and applying a leather conditioner periodically will significantly extend service life.
