FAQ

What is the lug width of the Breitling Superocean U17377211A1S1?

The lug width of the Breitling Superocean U17377211A1S1 is 18mm. This is a less common size compared to the 20mm standard prevalent in the sport-luxury segment, but it ensures precise proportions on a 36mm case. Before purchasing an aftermarket strap, it is advisable to verify the measurement with a digital calliper placed between the two lugs at the point closest to the case.

What is the best strap for the Breitling Superocean U17377211A1S1?

For the Breitling Superocean U17377211A1S1, with its black ceramic bezel and red gold details, the most suitable materials are dark alligator (jet black or Havana), bordeaux or dark brown shell cordovan, and vegetable-tanned calfskin. For aquatic or sporting use, a vulcanised rubber strap with a linear texture maintains the Superocean's aesthetic coherence. A brushed steel deployant clasp completes any configuration.

How do you change the strap on a Breitling Superocean U17377211A1S1?

The strap on the Breitling Superocean U17377211A1S1 is replaced using a spring bar tool to release the spring bars connecting the strap to the lugs. Care should be taken to avoid scratching the ceramic bezel or the red gold elements of the case. It is recommended to rest the watch on a soft cloth and use a fine-tipped tool. Alternatively, the operation can be carried out by a watchmaker or at the Casati Milano atelier.

Are there aftermarket straps compatible with the Breitling Superocean U17377211A1S1?

Yes, the Breitling Superocean U17377211A1S1 uses a standard 18mm lug width, compatible with any quality aftermarket strap made to that size. milanostraps.it offers a curated selection of 18mm straps in alligator, shell cordovan, vegetable-tanned calfskin and rubber, all precisely cut to ensure a correct fit with the case and no lateral play.

How long does a leather strap last on a Breitling Superocean U17377211A1S1?

The lifespan of a leather strap depends on material quality, frequency of wear and exposure to perspiration and moisture. A high-quality alligator or shell cordovan strap, vegetable-tanned and hand-finished, can last between 3 and 5 years with regular care. Immersion in water with a leather strap is not recommended; rubber is the preferred choice for diving use. Casati Milano straps carry an 18-month guarantee against manufacturing defects.
