FAQ
What is the lug width of the Oris Williams 01 774 7725 8794-Set RS chronograph?
The lug width of the Oris Williams 01 774 7725 8794-Set RS is precisely 20 millimetres. This dimension is specific to the model and requires a strap with identical 20mm width to ensure perfect fitment on the titanium case. The measurement must be verified directly on the lugs to avoid lateral play.
Which strap is best for the Oris Williams 01 774 7725 8794-Set RS?
There is no universal choice; it depends on intended use. Alligator leather in vegetable tanning offers formal elegance whilst maintaining the sporting character of the titanium case. Ballistic nylon NATO accentuates the motorsport technical nature of the model. Pressed rubber is a more radical choice for those seeking maximum resistance and material coherence with the case.
How do you change the strap on an Oris Williams 01 774 7725 8794-Set RS?
Changing requires a precision tool (spring bar tool) correctly sized to avoid scratching the case titanium. One must extract the elastic pins that secure the lugs to the case lugs—an operation requiring care to avoid damaging the timepiece. It is advisable to entrust the operation to a professional if lacking prior experience.
Are aftermarket straps truly compatible with the Oris Williams 01 774 7725 8794-Set RS?
Yes, provided the width is exactly 20 millimetres and the constructive tolerances are precise. An undersized strap creates dangerous play; one that is oversized will not enter the case lugs. It is essential to purchase from suppliers guaranteeing certified measurements and millimetre-level quality control.
How long does a natural leather strap last on this 44-millimetre case?
A vegetable-tanned calf leather on an Oris Williams 44mm withstands approximately 18–24 months with daily use, developing natural cracks and appreciable patina. A superior-quality alligator achieves 3–4 years before structural failure. Rubber and NATO offer virtually indefinite duration, although ballistic nylon may lose softness over time.
