Strap for Colt Chronograph Automatic Stainless Steel / Mariner Blue / Calf / Pin

The lug width of the Breitling Colt A1338811/C914/433X/A20BA.1 is 22mm. This measurement refers to the internal distance between the two case lugs at the strap attachment point and determines the correct strap size for this reference.

The ideal choice depends on intended use. For formal or business settings, a vegetable-tanned alligator or calfskin strap with a 22mm deployante or tang buckle complements the stainless steel case. For sport or water-related use, vulcanised rubber or ballistic nylon NATO straps provide waterproofing and mechanical resilience consistent with the Colt's tool watch heritage.

Use a fine-tipped spring bar tool, inserting the tip into the small notch on the inner side of the lug. Compress the spring bar and slide the strap free. The procedure takes approximately two minutes and requires no professional equipment, though care should be taken to avoid scratching the case surfaces.
