Strap for Colt 44 Automatic Mariner Blue / Calf

The lug width of the Breitling Colt A1738811.C906.105X is 22mm. This measurement is taken with a digital calliper positioned between the two lugs of the case, at the strap attachment point. It is essential to respect this measurement to ensure correct fitting and a secure strap hold.

For the Breitling Colt A1738811.C906.105X in 44mm brushed stainless steel, the most suitable materials are vegetable-tanned calfskin for refined everyday wear, matte alligator for formal occasions, and vulcanised rubber or ballistic nylon NATO for sporting contexts. The choice depends on the dial colour and intended use: a tobacco brown strap complements dark dials, whilst blue dials pair naturally with burgundy or navy tones.

The strap on the Breitling Colt A1738811.C906.105X is removed using a fine-tip or spatula-type spring bar tool, applying gentle lever pressure on the spring bar connecting the strap to the case lugs.

It is advisable to entrust this operation to a watchmaker or to visit the Casati Milano atelier for a professional strap change.

The lifespan of a leather strap on the Breitling Colt A1738811.C906.105X depends on leather quality and frequency of use. A high-quality vegetable-tanned calfskin strap can last between two and four years with regular wear, developing a distinctive patina over time. Alligator or shell cordovan straps, owing to their denser fibre structure, tend to offer superior longevity. Prolonged exposure to water and perspiration should be avoided to extend the strap's service life significantly.
