Strap for Formula 1 Quartz 43 Stainless Steel / Blue / Bracelet

The lug width of the TAG Heuer Formula 1 WAZ1010.BA0842 is 20mm. This measurement is obtained by positioning a digital calliper between the inner edges of the two metal lugs attached to the case. It is essential to respect this dimension when selecting an aftermarket strap to ensure secure and stable installation.

The best strap depends on your intended use. For formal or mixed contexts, genuine alligator with vegetable tanning offers elegance and a patina that improves over time. For pure sporting use, a technical rubber strap or a NATO ensures maximum resistance and functionality. Vegetable-tanned calfskin represents a versatile compromise between aesthetics and daily practicality.

The WAZ1010.BA0842 uses standard 1.5mm diameter spring bars. Using a spring bar tool (or even a flat knife point), gently press one of the two spring bars from below to release the bar, then remove the old strap. Insert the new strap by sliding the edges of the lugs into the appropriate slots and release the spring bar until it clicks. There is no need to disassemble the case.

Yes, the WAZ1010.BA0842 is fully compatible with any 20mm strap featuring standard spring bars. Milano Straps' artisanal straps, available in multiple materials (alligator, calfskin, rubber, NATO) and customisable in length, colour and stitching thread, adapt perfectly to the model without any construction compromise.

A high-quality leather strap, such as alligator or vegetable-tanned calfskin, typically lasts 4-7 years with regular use and ordinary maintenance (cleaning, protection from standing water, drying). Durability depends on intensity of use, climatic conditions and type of tanning. Vegetable tanning tends to last longer than chemical finishes. Milano Straps guarantees 18 months on made-to-measure straps created at the Casati Milano atelier.
