FAQ
What is the lug width of the Oris Divers 65 01 733 7707 4337-Set?
The lug width is precisely 20mm, measured as the distance between the case lugs. To verify, use a digital calliper positioned perpendicularly between the two lugs: the value must fall between 19.8 and 20.2mm. This precision is critical to ensure a correct strap fit without excessive play and to maintain the water resistance integrity of the watch.
Which strap is best suited for the Divers Sixty-Five?
The Divers 65 accommodates multiple solutions depending on usage. For authentic diving, a textured or smooth rubber strap delivers superior ergonomics and complete water impermeability without maintenance. For formal contexts, alligator with vegetable tanning or shell cordovan imparts gravitas, transforming the Divers 65 into dress-dive configuration. Military NATO evokes the watch's functional heritage, whilst vegetable-tanned calf offers an elegant compromise between comfort and aesthetic longevity.
How do you change the strap on the Oris Divers 65 01 733 7707 4337-Set?
The procedure requires a dedicated spring bar tool or precision tweezers. Position the watch on a soft cloth, locate the small slot adjacent to the lug, and gently insert the tool to press the spring inward. The spring retracts slightly, allowing the pin to slide out. Repeat on the opposite side. Insert the new strap by aligning the holes to the pin ends, then reposition the pins by pushing until you feel the engagement click. The process demands patience and millimetre precision.
Is an aftermarket strap completely compatible with this model?
Yes, provided the lug width is precisely 20mm and the strap ends respect the internal diameter of the pins (typically 1.6–1.8mm). Artisanal straps from milanostraps.it are constructed specifically for this width with tight tolerances. Verify the product is certified for 20mm lugs and that the buckle or keeper does not obstruct the unidirectional bezel rotation, otherwise operational practicality diminishes.
How long does a leather strap last on a diving watch like the Divers 65?
Longevity depends on tanning method and actual usage. Vegetable-tanned alligator—properly maintained, dried after moisture exposure, and occasionally treated with neutral wax—lasts 5–8 years under normal conditions. Shell cordovan, owing to its structural density, can exceed 10 years. However, frequent saltwater exposure significantly shortens lifespan: in these cases, rubber remains the rational choice. The natural patina developing on vegetable-tanned leather indicates aesthetic ageing, not functional compromise, until structural fibre rupture occurs.
