It features the Breitling B74 manufacture movement with COSC chronometric certification ensuring ±4 seconds per day accuracy.

Frequently asked questions

What is the lug width of the Breitling Colt A7438911/BD82/249X/A16D.1?

The lug width of the Breitling Colt A7438911/BD82/249X/A16D.1 is 18mm. This measurement is taken between the two lugs at the strap attachment point using a millimetre calliper. This dimension is relatively uncommon in Breitling's contemporary catalogue, making the 36mm Colt particularly distinctive for its classical proportions.

What is the best strap for the Breitling Colt 36mm?

For the satin-finished stainless steel Breitling Colt 36mm, a vegetable-tanned calf leather strap is the most appropriate choice for everyday wear, as it develops a natural patina over time. For formal occasions, a flat-belly Louisiana alligator strap complements the understated case finish. For sporting or aquatic use, a technical nylon NATO or vulcanised rubber strap is functionally consistent with the model's tool-watch heritage.

How do you change the strap on a Breitling Colt A7438911/BD82/249X/A16D.1?

To replace the strap on the Breitling Colt A7438911/BD82/249X/A16D.1, use a springbar tool inserted into the lug hole to compress the springbars and release the strap. Care must be taken to avoid scratching the satin-finished stainless steel case. It is advisable to use a watchmaker's cushion mat and, if in doubt, to entrust the operation to a qualified watchmaker.

Are there aftermarket straps compatible with the Breitling Colt 36mm?

Yes, a wide range of aftermarket straps are compatible with the Breitling Colt 36mm, provided they conform to the 18mm lug width. Milanostraps.it offers a curated selection of handcrafted straps in leather, alligator, calf and technical materials, all verified for compatibility with 18mm lugs. The buckle or deployant clasp should be selected in satin-finished steel to match the original case finish.

How long does a leather strap last on a Breitling Colt?

The lifespan of a leather strap depends on hide quality, frequency of use and exposure to perspiration and moisture. A high-quality vegetable-tanned calf strap worn daily under moderate conditions typically lasts 18 to 36 months. A superior-grade alligator strap, properly maintained with leather conditioner and kept away from water, can last well over three years. Casati Milano offers an 18-month guarantee covering manufacturing defects.
