Frequently asked questions

What is the lug width of the Breitling Superocean Heritage '57 A103702A1C1X1?

The Breitling Superocean Heritage '57 A103702A1C1X1 features a lug width of 20 mm. This is a standard size, compatible with a wide range of aftermarket straps in leather, nylon or rubber.

What is the best strap for the Breitling Superocean Heritage '57?

The ideal choice depends on intended use and aesthetic preference. For formal occasions, an alligator strap in black or navy with a steel buckle works superbly. For everyday or aquatic use, vegetable-tanned calfskin develops a genuine patina over time, whilst a NATO nylon strap or vulcanised rubber are the most practical options for water exposure.

How do I change the strap on the Breitling Superocean Heritage '57?

The strap is removed by compressing the spring bars located between the lugs using a spring bar tool. The operation takes under two minutes and requires no professional equipment. It is advisable to work on a soft surface to avoid scratching the case.

Are there aftermarket straps compatible with the Breitling Superocean Heritage '57?

Yes. Any strap with a 20 mm lug width and standard spring bars is compatible with the Breitling Superocean Heritage '57. Milanostraps.it offers a curated selection of handcrafted 20 mm straps in various materials, all fully compatible without the need for adapters.

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

The lifespan of a leather strap depends on leather quality, care and usage. A high-quality calfskin or alligator strap, properly maintained with leather conditioner every 3 to 6 months and kept away from prolonged water exposure, can last between 2 and 5 years. Shell cordovan straps, due to the density of the hide, tend to offer greater longevity. Casati Milano provides an 18-month warranty against manufacturing defects.
