The strap for this watch is made to measure
On the Oris Williams the bracelet is drawn as part of the case: no catalogue strap will fit. In the atelier we take the measurements on the watch itself and build the strap on the piece — that is the work of Casati Milano.

What is the lug width of the Oris Williams 01 635 7560 4161?
The lug width of the 01 635 7560 4161 is 35 millimetres. This dimension is specific to the Williams chronograph and represents the distance between the two lugs of the quick-release spring. It is essential to verify this measurement before ordering an aftermarket strap to ensure perfect compatibility and correct aesthetics on the wrist.
Which strap best complements the Oris Williams chronograph?
The Oris Williams 01 635 7560 4161, with its motorsport heritage, pairs beautifully with straps in cognac alligator or dark calf leather for formal wear, whilst a dark grey or navy NATO maintains racing thematic coherence. For sports contexts, a grey anthracite FKM rubber strap guarantees robustness and practicality. The choice depends on the intended use and season.
How do I change the strap on the Oris Williams 01 635 7560 4161?
Strap replacement is straightforward: position the watch face-down on a soft surface, locate the small lever or button of the quick-release spring on the lug shoulder (internal side of the case), press gently inward and slide the strap outward. To install the new 35mm strap, align the lug width with the shoulder and press until you hear the click of the spring engaging.
Can I use an aftermarket strap with 35mm lug width?
Yes, absolutely. Any strap with a 35 millimetre lug width is compatible with the 01 635 7560 4161. Quality aftermarket straps in vegetable-tanned leather, FKM rubber, polyamide NATO, or alligator often offer superior craftsmanship compared to Oris original equipment, allowing you to customise the chronograph's style whilst maintaining perfect structural compatibility.
How long does a leather strap last on a 40mm watch like the Williams?
A quality leather strap (alligator, calf with vegetable tanning) typically lasts 3–5 years with daily wear, provided it is kept dry and protected from prolonged moisture. A thicker structured leather strap can last up to 7 years. Durability increases significantly if the watch is not worn daily. Artisanal aftermarket straps often exceed OEM strap longevity thanks to selected hides and reinforced stitching.
