The Heritage

The TAG Heuer Carrera CBG2090.FT6145 is a 43mm chronograph combining stainless steel and black ceramic, evolved from the 1963 racing icon. It features the in-house Heuer 02 automatic movement with 4 Hz frequency and 70-hour power reserve, complemented by a column-wheel chronograph mechanism. The 20mm lug width accommodates the integrated bracelet design and squared case architecture reflecting the brand's racing heritage.

FAQ

What is the lug width of the TAG Heuer Carrera CBG2090.FT6145?

The lug width is 20mm. This measurement is determined by measuring the internal distance between the case lugs with a digital caliper. It is essential for selecting a compatible strap and ensuring perfect and stable fitment.

What is the best strap for the TAG Heuer Carrera CBG2090.FT6145?

The best strap depends on usage. For formal contexts, we recommend alligator with vegetable tanning or Hermès calf; for sport, vulcanised rubber with aggressive texture; for versatility, technical nylon or ballistic fabric. The choice should reflect the cool stainless steel and ceramic elegance of the case.

How do I change the strap on the TAG Heuer Carrera CBG2090.FT6145?

Obtain a spring bar removal tool. Position the watch face down, insert the tool into the small hole beneath the lug to release the spring bar, remove the original strap, align the new strap with the pins, and secure with a smooth inward motion until the safety click engages.

Is a quality aftermarket strap compatible with the CBG2090.FT6145?

Yes, provided the lug width is 20mm. Artisanal straps from specialised producers such as Milano Straps guarantee certified compatibility and bespoke customisation, preserving the aesthetic proportion of the case.

How long does a leather strap last over time?

A fine leather strap with vegetable tanning and manual construction lasts 3–5 years with daily use if subjected to periodic maintenance: gentle cleaning, air drying, and protection from excessive moisture and perspiration. Natural ageing imparts patina whilst preserving structure if the strap is manufactured by experienced craftsmen.
