Frequently asked questions

What is the lug width of the Breitling Colt A17313101F1X2?

The Breitling Colt A17313101F1X2 has a lug width of 20 mm, measured between the inner surfaces of the lugs using a calliper. This measurement must be respected precisely to ensure a secure and aesthetically correct strap fitment.

What is the best strap for the Breitling Colt A17313101F1X2?

For the Breitling Colt A17313101F1X2, the most fitting options include: hornback or classic-grain alligator for a formal and technical look, vegetable-tanned calf leather for everyday wear with natural patina development, NATO nylon for military authenticity, and vulcanised rubber for aquatic or sports use. A deployant clasp in steel enhances both ergonomics and security.

How do you change the strap on the Breitling Colt A17313101F1X2?

The strap on the Breitling Colt A17313101F1X2 is removed using a flat-tipped spring bar tool or a dedicated lug lever to release the spring bars securing the strap to the lugs. Work on a soft surface to protect the case finish. The operation takes approximately two minutes and does not require professional tools, though a watchmaker is recommended for preserving the case surfaces.

Are there aftermarket straps compatible with the Breitling Colt A17313101F1X2?

Yes, the Breitling Colt A17313101F1X2 accepts any aftermarket strap with a 20 mm attachment, provided it features quality spring bars and a centre keeper proportionate to the strap thickness. Milanostraps.it offers a curated selection of handcrafted 20 mm straps made from selected leathers with stainless steel or PVD buckles, proportioned to the 41.10 mm case.

How long does a leather strap last on a Breitling Colt A17313101F1X2?

The lifespan of a leather strap depends on tanning quality, exposure to perspiration and water, and daily care. On an actively worn Colt, a quality calf leather strap typically lasts 18 to 30 months. A premium alligator strap, maintained with nourishing cream and protected from moisture, can exceed three years of use. Milanostraps offers an 18-month guarantee against manufacturing defects.
