Frequently asked questions
What is the lug width of the Oris Williams 01 733 7716 4164-07 8 24 50?
The lug width is 20mm. This dimension refers to the internal distance between the two lugs (spring bar holes) that suspend the strap to the case, measured from inner edge to inner edge. It is a standard width in the sports-elegant segment of Swiss watchmaking.
Which strap is recommended for the Oris Williams?
Vegetable-tanned leather straps in dark brown or cognac tones offer formal elegance. For daily wear, high-density nylon NATO straps guarantee practicality and versatility. For those seeking refinement, alligator leather in forest green or intense black represents an exceptional choice. FKM rubber straps are ideal for aquatic environments or humid climates.
How do I change the strap on the Oris Williams 01 733 7716 4164-07 8 24 50?
Strap change requires a spring bar tool (a specific instrument for pin removal). Gently insert the tool blade under the spring bar from below, applying controlled pressure to flex the internal spring. Once extracted, the strap detaches easily. For installation, align the new strap holes, insert the spring bar into position, and verify correct placement by gently flexing the wrist.
Are aftermarket straps compatible with the Oris Williams?
Yes, all straps with a 20mm lug width are theoretically compatible. However, it is essential that the leather thickness in the passage area does not exceed the geometry of the case lugs. Milano Straps' artisanal straps are manufactured to tight tolerance specifications, ensuring fluid insertion and positional stability without requiring adjustments.
How long does a leather strap last on the Oris Williams?
Longevity depends on intensity of use, climate, and maintenance. A quality vegetable-tanned strap, worn daily, has a lifespan of 3-5 years before replacement is necessary. Prolonged exposure to high humidity, heat, and chemical agents (perfumes, deodorants) significantly reduces this estimate. Preventive maintenance with natural oils or leather-specific waxes extends strap lifespan.
