Superocean A1731267.A775.238S— lug 18mm

The Breitling Superocean A1731267.A775.238S has a lug width of 18 mm. This measurement is specific to the 36 mm case variant and differs from larger Superocean models, which typically use 20 or 22 mm lugs. To confirm, measure the internal distance between the two lugs using a digital calliper.

The ideal choice depends on the intended use. For formal or business settings, an 18 mm alligator strap in vegetable-tanned leather with a brushed steel buckle best complements the watch's instrument-grade aesthetic. For aquatic use, a vulcanised rubber strap is the most technically appropriate option. A ballistic nylon NATO strap offers an authentic sports-casual register.

The strap is replaced by removing the spring bars from the case lugs using a dedicated spring bar tool or flat-blade lever. The spring bars must be compatible with an 18 mm lug width. Work on a soft surface to protect the bezel and case from scratches. If in doubt, a watchmaker or the Casati Milano atelier can carry out the replacement safely.

Yes. Any strap with an 18 mm attachment width is technically compatible. Milano Straps offers a curated range of handcrafted leather, rubber and nylon straps in this size, made from premium materials with customisable finishes. Replacement spring bars are generally included for straightforward fitting.

Longevity depends on the material and frequency of use. A quality vegetable-tanned alligator strap, properly maintained with leather conditioner and kept away from salt water, can last three to five years with daily wear. Shell cordovan is even more durable due to its dense fibre structure. Calfskin is more affordable but more susceptible to moisture. For a Superocean worn regularly in water, a rubber strap offers the greatest longevity.
