FAQ
What is the lug width of the Breitling Superocean Heritage '57 A10340A11A1X1?
The lug width of the Breitling Superocean Heritage '57 A10340A11A1X1 is 18mm. This measurement must be taken internally between the two lugs using a digital calliper, at the point where the strap meets the case. Respecting this dimension is essential to ensure a precise fit and correct aesthetic result.
What is the best strap for the Breitling Superocean Heritage '57 A10340A11A1X1?
The most suitable materials for the Superocean Heritage '57 A10340A11A1X1 are vegetable-tanned calf leather in tobacco or cognac tones, smooth alligator for formal occasions, nylon NATO for maximum fidelity to the vintage 1950s aesthetic, and vulcanised rubber for aquatic use. The choice depends on the context of wear and the desired chromatic pairing with the dial.
How do you change the strap on a Breitling Superocean Heritage '57?
To replace the strap on the Superocean Heritage '57, a spring bar tool is required to remove the 18mm spring bars from the case lugs.

It is advisable to work on a soft surface and, if in doubt, to entrust the operation to a watchmaker or the Casati Milano atelier.

How long does a leather strap last on a Breitling Superocean Heritage '57?
