Strap for Carrera Calibre Heuer 02 45 Rose Gold / Skeleton / Alligator

The lug width of the TAG Heuer Carrera CBG2A51.FC6450 is 20mm. This dimension is determined by the geometry of the 45-millimetre case and is a standard construction specification for sports chronographs in this size range. It is essential to verify that any aftermarket strap is dimensioned precisely for 20mm to ensure compatibility and correct fitting to the case lugs.

For a 45mm chronograph in stainless steel and rose gold such as the CBG2A51.FC6450, we recommend an alligator strap in cognac or dark brown tones: the natural scale texture offers mechanical grip and develops a rich patina over time. Alternatively, vegetable-tanned calf leather with oil-wax treatment offers modernity and sustainability, ideal for those seeking contemporary aesthetics with chromatic evolution over the months.

Strap replacement is accomplished by extracting the spring bars that anchor the strap to the case lugs. Using a dedicated tool (spring bar tool), gently push the pin inward until one end of the strap is freed, then extract the entire pin. The reverse process secures the new strap. It is advisable to work with care to avoid scratching the case: many collectors entrust this operation to specialised professionals.

Yes, the CBG2A51.FC6450 is fully compatible with aftermarket straps dimensioned for 20mm. At Milano Straps you will find a curated selection of artisanal straps in alligator, shell cordovan, calf and rubber, all customisable in size, initials and stitch type. Technical compatibility is guaranteed; elevated construction quality ensures durability and comfort superior to many OEM models.

The lifespan of a natural leather strap depends on intensity of use, climate conditions and type of tanning. A quality artisanal alligator or shell cordovan can last 5-8 years with regular maintenance (drying after humidity exposure, protection from direct impact). Vegetable-tanned calf requires greater care in humid environments but develops aesthetic character over time. Milano Straps offers 18-month warranty on all straps produced by the Casati Milano atelier.
