Strap for Formula 1 Quartz 43 Stainless Steel / Bundesliga

The lug width of the TAG Heuer Formula 1 WAZ1013.BC0889 is 20mm. This measurement refers to the space between the lugs on the watch case where the strap attaches via spring bars. It is essential to choose a strap that is exactly 20mm wide to ensure perfect compatibility.

The best strap depends on your intended use and personal preference. For those who appreciate elegant patina development over time, we recommend vegetable-tanned alligator. For those seeking durability and increasing smoothness with wear, shell cordovan is exceptional. Italian grained calf leather offers a balance between practicality and refinement, whilst rubber or NATO fabrics are ideal for technical applications.

To change the strap, extract the spring bars from the watch lugs using a dedicated spring bar remover tool. Compress the pin gently to release it from the lug, then remove the old strap. Once the lugs are free, align the new strap with the lug holes and reinsert the spring bars until they click into place. If you lack confidence, consult a professional watchmaker.

Yes, provided it is a 20mm strap. Milano Straps offers a carefully curated selection of artisanal straps compatible with this lug width, crafted from premium materials such as alligator, shell cordovan, and Italian calf leather. All available straps are tested to guarantee maximum compatibility and quality standards.

The lifespan depends on the material and usage intensity. A quality alligator or calf leather strap, with proper care, maintains structural integrity for 3–5 years of daily wear. Shell cordovan, owing to its superior density, can last considerably longer. Wear typically manifests first at the stitching; to extend lifespan, avoid prolonged water exposure and apply specialist leather creams occasionally.
