FAQ
What is the lug width of the Breitling Superocean U173771A1A1S1?
The Breitling Superocean U173771A1A1S1 has a lug width of 18 mm. This measurement should be taken with a millimetre calliper at the inner base of the two lugs. It is the critical dimension when selecting a compatible strap to ensure a proper fit with no lateral play.
What is the best strap for the Breitling Superocean 36 U173771A1A1S1?
Given the steel and red gold case configuration of the Superocean 36, a vegetable-tanned alligator strap with a lustrous grain is the most coherent choice for a formal-sports aesthetic. Tobacco brown or burgundy tones complement the warm reflections of the red gold. For everyday or aquatic use, a technical NATO or a vulcanised rubber strap in 18 mm provides full functionality without aesthetic compromise.
How do you change the strap on a Breitling Superocean U173771A1A1S1?
The strap on the Superocean 36 is secured via standard 18 mm spring bars. Replacement requires a thin-bladed screwdriver or a dedicated spring bar tool to compress the bars and release them from the lug holes. The operation takes only a few minutes without specialist watchmaking skills, though working on a soft surface is advisable to avoid scratching the case.
Are there aftermarket straps compatible with the Breitling Superocean U173771A1A1S1?
Yes. Any strap with an 18 mm straight-end attachment is technically compatible with the Superocean U173771A1A1S1. Milanostraps.it offers a curated selection of handcrafted leather, rubber and textile straps made specifically for 18 mm lugs, available with buckle or deployant clasp, designed to complement the two-tone steel and red gold aesthetic of the case.
How long does a leather strap last on a Breitling Superocean?
The lifespan of a leather strap depends on the quality of the hide, the tanning method and how it is worn. A handcrafted alligator or shell cordovan strap finished with vegetable tanning, with ordinary care — avoiding prolonged exposure to water and perspiration — can last between three and seven years while retaining an impeccable appearance. The patina that develops over time is an integral part of the strap's aesthetic value. Milanostraps.it provides an 18-month manufacturing warranty on all Casati Milano straps.
