Frequently asked questions

What is the lug width of the Breitling Transocean AB015212/BF26/105X/A20BA.1?

The lug width of the Breitling Transocean AB015212/BF26/105X/A20BA.1 is 22mm. This measurement is taken with a calliper across the internal gap between the two lugs at the base of the case, and is the key parameter for selecting a compatible strap without lateral play or forced fitting.

What is the best strap for the Breitling Transocean AB015212/BF26/105X/A20BA.1?

For the Transocean, a wide-grain alligator strap in cognac or tobacco tones best complements the chronograph's elegant character. A vegetable-tanned Tuscan calf strap that develops a natural patina over time is also highly regarded by collectors. For a more casual look, two-tone NATO straps reference the model's aviation heritage. All straps must have a 22mm lug width.

How do you change the strap on the Breitling Transocean AB015212/BF26/105X/A20BA.1?

To change the strap, use a spring bar tool to remove the spring bars between the lugs. It is advisable to work on a soft cushion to protect the dial and case from scratches. Alternatively, Casati Milano offers a professional strap replacement service at the atelier by appointment.

How long does a leather strap last on the Breitling Transocean AB015212/BF26/105X/A20BA.1?
