FAQ
What is the lug width of the Breitling Superocean A1739102BA78435X?
The Breitling Superocean A1739102BA78435X has a lug width of 20mm. This measurement is taken with a digital calliper across the inner gap between the two lugs at the point where the strap or bracelet attaches — not across the case diameter. Any 20mm strap with straight ends is compatible with this reference.
What is the best strap for the Breitling Superocean A1739102BA78435X?
The ideal choice depends on the context. For aquatic or sporting use, vulcanised rubber is the most practical option. For urban or professional settings, an alligator or grained vegetable-tanned calf strap complements the Superocean's instrumental character. A nylon NATO strap remains the most faithful to the watch's tool-watch DNA. In all cases, the strap end must be straight to seat correctly in the lug geometry of this model.
How do you change the strap on a Breitling Superocean A1739102BA78435X?
The bracelet or strap is secured to the lugs via spring bars. Replacement requires a spring bar tool to compress and release the bars from the lug holes. Care must be taken not to scratch the stainless steel case: masking tape applied to the bezel and adjacent surfaces is recommended to protect the finish during the operation.
Are there aftermarket straps compatible with the Breitling Superocean A1739102BA78435X?
Yes. Any 20mm strap with straight ends is technically compatible with the Breitling Superocean A1739102BA78435X. Milano Straps offers a curated selection of handcrafted straps in various leathers and materials, produced with profiled ends for a precise fit against the Superocean lugs. For a fully bespoke result, the Casati Milano atelier produces made-to-measure straps tailored to the client's wrist dimensions.
How long does a leather strap last on a Breitling Superocean?
The longevity of a leather strap depends primarily on the quality of the hide, frequency of wear, and exposure to water and perspiration. A high-quality alligator or calf strap, regularly conditioned with neutral products and kept away from water, can last between three and seven years whilst retaining structural integrity and a dignified appearance. Shell cordovan, owing to its dense fibre structure, is the most durable among classic leathers. Casati Milano straps carry an 18-month warranty against manufacturing defects.
