Strap for Formula 1 Quartz 35 PVD / Black - Diamond / Calf

The lug width of the TAG Heuer Formula 1 WBJ1317.FC8230 is 20mm. This dimension represents the horizontal distance between the two attachment pins on the case and ensures compatibility with aftermarket straps manufactured to this specific width.

For the WBJ1317.FC8230, dark brown or black alligator straps are recommended for formal elegance, whilst vegetable-tanned leather is ideal for those seeking a patina that evolves over time. The choice depends on usage: sport-formal styling requires alligator; daily elegant wear prefers treated calf or rubber.

If the model features an integrated bracelet, the procedure is: 1) Carefully remove the side pass-through loops using a dedicated tool; 2) Extract the attachment pins from the case; 3) Insert the new strap into the lugs and secure the pins.

A quality leather strap (alligator or calf) typically lasts 2-3 years with daily wear. Vegetable-tanned leather tends to last slightly longer because the hide develops a protective patina over time. The Casati Milano atelier provides an 18-month warranty on all bespoke straps.

Yes, a quality 20mm strap is fully compatible. Ensure that the leather thickness (typically 3-4mm) does not create excessive friction within the attachment slots. Straps from milanostraps.it are manufactured to precision standards for perfect fit and long-lasting performance.
