Strap for Chronomat Colt 44 Automatic Blue / Calf / Folding

The lug width of the Breitling Colt A17388101C1X3 is 22mm. This measurement is taken with a calliper across the internal distance between the two lugs on the case back. Any strap with a 22mm end width is compatible with this reference.

For the 44mm steel Colt A17388101C1X3, the most suitable materials are Tuscan vegetable-tanned calfskin for everyday elegant wear, alligator leather for more formal occasions, nylon NATO for sporting use, and vulcanised rubber for aquatic environments. The choice depends on intended use and aesthetic preference.

To replace the strap on the Colt A17388101C1X3, you will need a fine-tipped spring bar tool or a suitable flat-head screwdriver. Insert the tool into the lug slot, compress the spring bar, and slide out the strap. The operation does not require professional tools but should be carried out carefully to avoid scratching the steel lugs.

The lifespan of a leather strap depends on leather quality, usage, and maintenance. A high-quality vegetable-tanned leather strap, kept away from excess water and perspiration and periodically treated with neutral wax, can last between 3 and 6 years while retaining good structural integrity. The keeper and the hole area are the main wear points to monitor.
