Strap for Formula 1 Calibre 16 44 Stainless Steel / Grey / Bracelet

The lug width of the TAG Heuer Formula 1 CAU2010.BA0873 is 20 millimetres. This measurement corresponds to the distance between the two spring bars that connect the strap to the case. When ordering a replacement strap, it is essential to verify that it is constructed specifically for 20mm, as this dimension is unique to this generation of Formula 1.

For the TAG Heuer Formula 1 in ceramic and steel, natural alligator is the premium choice: its pyramidal grain interacts with the technical aesthetics of the case without competing visually. Vegetable-tanned calfskin offers a patina that evolves over time and superior breathability. Structured rubber is ideal for those prioritising waterproof durability and driving grip. The choice depends on use: formal elegance requires alligator or calfskin; daily driving suggests rubber.

To replace the strap, locate the two spring bars hidden between the case and strap. Use a dedicated extraction tool or small flathead screwdriver to gently push towards the case centre: the bar will retract, allowing the old strap to slide off. Insert the new 20mm strap by positioning one end first, then push the bar until it clicks into place. Work carefully on a soft surface to avoid scratching the case.

Yes, the TAG Heuer Formula 1 CAU2010.BA0873 accepts any strap constructed to the 20mm standard. Artisanal quality straps in alligator, calfskin, shell cordovan or rubber are fully compatible. Ensure the strap is specifically dimensioned for 20mm and that the spring bars are installed correctly. Specialised ateliers provide customisable straps in leather, thread colour and initials.

An artisanal quality leather strap has a lifespan of 3 to 7 years, conditioned by daily use, sun exposure and perspiration, and periodic moisturising care. Vegetable-tanned leather ages elegantly, developing patina; alligator maintains structure longer if protected from moisture damage. Technical rubber has extended lifespan (8–10 years) but loses grip over time. The standard warranty on artisanal straps is 18 months.
