Strap for Williams Chronograph Stainless Steel / Carbon / Rubber

The lug width is 22mm. This measurement is taken between the inner walls of the attachment pins and represents the standard construction specification for this model. It is essential to verify this measurement with a digital calliper before purchasing any aftermarket strap, as even minor variations will compromise the fit.

For the Williams 01 774, we recommend alligator in matte finish or with irregular texture, which echoes the brushed steel case surface. Alternatively, vegetable-tanned calf leather offers elegant ageing and transforms the chronograph into a daily luxury tool. Ballistic nylon NATO straps represent the pure technical choice, ideal for those wishing to maintain the aeronautical heritage of the Williams partnership.

Changing a strap on a 22mm lug width requires a specific tool: the spring bar tool. Position the curved end of the tool beneath the attachment pin from the inner side, apply gentle pressure until the spring yields, then extract the pin. Repeat on the other side. When inserting the new strap, align the attachment holes with the pins and press with controlled movement until the locking click is heard.

All straps with a standard 22mm attachment are compatible with this model. milanostraps.it offers a complete selection of artisanal straps in leather, alligator, shell cordovan, NATO, and FKM rubber, all crafted with precise 22mm lugs and ready for dispatch. We recommend browsing the collection filtered by 22mm lug width.

A quality artisanal leather strap with vegetable tanning lasts an average of 3-5 years with daily use, depending on sun exposure, humidity levels, and maintenance frequency. Leather deteriorates more rapidly if exposed to acidic perspiration or stagnant fresh water. Alligator or shell cordovan straps, being more robust fibres, extend durability to 5-7 years. FKM rubber has similar lifespan but visibly oxidises over time, though structural integrity is maintained.
