Strap for Oris Divers 65 01 733 7795 4055

The lug width of the Divers 65 is exactly 19mm, a proportion directly derived from the 39mm case diameter. This measurement represents the internal distance between the upper and lower attachment points of the case, and any aftermarket strap must have the same lug width to fit without lateral play.

Tuscan vegetable-tanned leather in dark brown remains the most balanced choice: it ages gracefully, provides initial water resistance, and creates perfect aesthetic contrast with the black satin dial. However, for frequent use in marine environments, a rubber strap with medium grain offers superior practicality and zero maintenance.

You must use a spring bar tool to remove and insert the spring bars connecting the strap to the case lugs. Insert the flat tip of the tool into the small hole beneath the lug, gently push to retract the internal spring, and slide the strap out. Reverse the process to install the new strap, ensuring the passantes fit correctly within the 19mm lug width.

All straps with a 19mm lug width are compatible: leather, NATO, rubber, shell cordovan, alligator, and calf. Always verify that the strap passantes match exactly 19mm in width, as even a 0.5mm discrepancy prevents installation without forcing the lugs.

A vegetable-tanned leather strap on a dive watch like the Divers 65 has an average lifespan of 2-3 years with regular use and periodic maintenance. Frequent exposure to saltwater, chlorine, and UV rays accelerates aesthetic aging, although the leather remains structurally sound. To extend longevity, remove the strap after saltwater immersions, rinse in fresh water, and air-dry completely in shade.
