Strap for Oris Divers 65 01 733 7795 4054

The Oris Divers Sixty-Five, reference 01 733 7795 4054, features a lug width of 19mm. This measurement represents the precise distance between the pins that secure the strap to both sides of the case. It is crucial to measure the lug width correctly by removing the original strap and calculating the available space between the two lugs, rather than measuring the strap itself. The 19mm size ensures excellent compatibility with a wide selection of aftermarket options.

For the Divers 65, the recommended strap options include vegetable-tanned leather (Tuscan leather in dark brown to emphasise the professional character), natural alligator in cognac (for sophisticated elegance), NATO in cotton or nylon (for versatility and practicality), or FKM rubber (for pure diving functionality). Your choice should reflect the intended use: vegetable-tanned leather develops a magnificent patina over time, whilst rubber is ideal for diving and marine environments.

To replace the strap on the 01 733 7795 4054, remove the spring bars (pins) connecting the strap to the case lugs using a dedicated spring bar tool. Position the tool perpendicular to the pins and apply gentle pressure to extract them. Once removed, slide off the old strap and insert the new one by aligning the holes. Reinsert the spring bars, ensuring they are properly secured. This is a straightforward, reversible procedure that allows you to alternate straps according to occasion.

Yes, any strap with a 19mm lug width is compatible with the Divers 65 01 733 7795 4054, provided the spring bars are standard diameter (1.8mm, length 6–7mm) and the overall strap width does not exceed the case margins. Before purchasing, verify that the aftermarket strap explicitly declares compatibility with 39mm watches and 19mm lugs. Bespoke, handcrafted straps offer maximum aesthetic and qualitative customisation.

Leather strap durability depends on tanning quality and intensity of use. A Tuscan leather strap with vegetable tanning can last 3–5 years under moderate use whilst developing a fascinating patina over time. Vegetable-tanned leather is more robust than chrome-tanned alternatives but is sensitive to humidity and extreme temperature fluctuations. To extend lifespan, avoid prolonged immersion in water (the Divers 65 is water resistant to 300m, but the strap is not) and occasionally condition the leather with natural oils. Rubber and NATO straps offer superior durability and tolerate moisture far better.
