Strap for WilliamsF1 Team Day Date 42 Stainless Steel / Black / Rubber

The lug width of the Oris Williams 01 635 7595 4164-07 4 25 01 is 22 millimetres. This measurement is determined by the distance between the two metal ends (spring bars) that protrude from the case and is critical for selecting compatible straps without compromising fit or lateral play.

The choice depends on intended use: alligator or vegetable-tanned calf emphasises elegance without compromising sporting character; NATO or vulcanised rubber straps maintain pure racing identity. For the 01 635 7595 4164-07 4 25 01, we recommend dark tobacco calf or intense black with stainless steel deployante for formal-sporting versatility.

Using a spring bar tool, apply gentle pressure to one of the metal ends beneath the case to release the existing strap. Insert the new 22mm strap into the same seats, ensuring the anse ends adhere completely to the spring bars. This operation requires precision to avoid scratching the case.

Yes, absolutely. Any certified 22mm strap is compatible with the 01 635 7595 4164-07 4 25 01. We recommend verifying actual width before purchase and selecting straps from specialist manufacturers to ensure build quality and colour stability over time.

Vegetable-tanned calf or alligator offers 2–4 years of daily wear, developing characteristic patina. Durability depends on moisture exposure, UV rays and frequency of use. Rubber straps last 5–7 years, fabric NATO straps 4–6 years. Rotating between straps extends the life of each.
