Strap for Superocean 44

The lug width of the Breitling Superocean A1739102BA78131S is 20mm. This measurement is taken with a digital calliper positioned between the inner walls of the lugs, perpendicular to the longitudinal axis of the case. It is the most widely adopted standard in professional watchmaking and ensures broad strap compatibility.

The ideal choice depends on intended use. For maintaining the tool watch diving identity, vulcanised rubber or ballistic nylon NATO straps are the most coherent options. For a sport-formal context, a matte alligator or vegetable-tanned calf strap complements the brushed steel case without undermining its character. A steel deployant clasp integrates seamlessly with the case's metallic palette.

Strap replacement requires a fine-tipped spring bar tool. Insert the tip into the slot of the spring bar between the lug and the strap, compress the bar inward, and slide the strap free. Care should be taken to avoid scratching the steel lugs: using a protective leather pad or masking tape on the lugs during the procedure is strongly recommended.

Yes. Any 20mm strap with standard or slightly curved ends is compatible with the Breitling Superocean A1739102BA78131S. Milano Straps offers a curated selection of handcrafted straps in leather, alligator, calf and rubber, specifically tested on this lug width, with spring bars included for immediate fitting.

Longevity depends on leather quality, frequency of use, and exposure to moisture and perspiration. A quality vegetable-tanned leather strap, kept dry and regularly treated with a conditioning cream, can last between two and five years under daily use. For humid or marine environments, rubber or waterproof NATO straps are the more practical alternative.
