Frequently asked questions
What is the lug width of the Oris Divers 65 01 733 7707 4055-07 8 20 18?
The Oris Divers 65 ref. 01 733 7707 4055-07 8 20 18 features a 20mm lug width. This dimension can be verified by measuring the distance between the two strap attachment holes using a digital calliper. The 20mm width positions the model in an intermediate range, ideal for the 40mm case diameter and proportional to the contemporary wrist. Precise measurement is essential before ordering a replacement strap.
What strap type is recommended for the Oris Divers 65?
This depends on intended use and aesthetic preference. For vintage-classical styling: alligator or vegetable-tanned calf leather. For daily practicality: NATO in vegetable-tanned cotton or leather with deployante clasp. For authentic diving: FKM rubber (fluoroelastomer). Each material accentuates a different facet of the watch, from the natural patina development of leather to the technical reliability of rubber.
How do I change the strap on an Oris Divers 65?
The Oris Divers 65 uses standard spring bar attachments. Obtain a dedicated spring bar removal tool (ball tool or specialist strap changer). Position the watch horizontally with lugs facing outward, gently compress one spring and slide it from its seat, repeat on the opposite side. Install the new strap by reversing the procedure. Never force: the risk is damaging the lug holes. If uncertain, consult a specialised atelier.
Can I fit an aftermarket strap on this Oris model?
Yes, provided it is compatible with the 20mm lug width. Whilst Oris offers official straps, the aftermarket provides superior artisanal quality in leather selection, construction and finishing details. Verify that the strap width is precisely 20mm and that spring bars are included. Specialised straps for this dimension guarantee proportionate ergonomics and aesthetics.
How long does a leather strap last on a watch like this?
A quality leather strap, vegetable-tanned, typically lasts 2–4 years with moderate daily use. Durability depends on humidity, sunlight exposure, usage frequency and maintenance. Shell cordovan or alligator straps tend to age more gracefully, developing natural patina. Rubber straps last 5–7 years before stiffening. Strap replacement is not wear; it is natural evolution. Maintaining spare straps allows rotation and extends overall longevity.
