Strap for Oris Big Crown 01 594 7695 4361

The lug width of the Oris Big Crown 01 594 7695 4361 is 14mm. This measurement refers to the distance between the internal attachment pins: it is a critical parameter to ensure that the strap is securely fastened without mechanical play. Always measure between the internal pins using a ruler, not on the external surface of the case which may be misleading by 0.5mm.

For the 01 594 7695 4361, we recommend alligator in fine grain black or dark brown if you desire continuity with the aviator heritage, or calf leather with vegetable tanning in cognac to develop natural patina over time. A NATO strap in grey or navy cotton is a rigorous sporty alternative. For water use, thin vulcanised rubber in black keeps the wrist dry and simplifies daily maintenance.

Strap replacement is a straightforward operation: use a spring bar tool or a small flat screwdriver to compress the pins that hold the strap in position. Push inward and simultaneously extract the lug, repeat on the other side. Insert the new 14mm strap by aligning the holes, verify that the pins click into place with a small snap, and test by pulling: if it does not give, the strap is correctly secured.

Yes, all straps with a 14mm lug width are compatible at the mechanical level. Quality depends on the manufacturer: artisanal straps in Italian leather or African alligator offer lasting durability and natural patina development. Verify that the strap is genuinely 14mm by measuring it with a ruler between the lug holes: a 16mm or 12mm strap would not secure correctly.

A quality artisanal leather strap, if subjected to basic maintenance, lasts on average 18-36 months before showing structural failures (cracks at creases, thinning in the wrist area). Durability depends on frequency of wear, exposure to humidity and perspiration, and periodic protective treatments. Vegetable-tanned leather tends to last longer than chrome-tanned leather because the fibre remains more stable. Alligator resists moisture better and degrades less rapidly than more ordinary leathers.
