Selected for the 20 mm lug width · workshop selection
What length do I need?
Measure your wrist with a tailor's tape or a piece of string, comfortably snug.
| Wrist circumference | Length (long side / short side) |
|---|---|
| 15.0–16.4 cm | 120 / 70 mm |
| 16.5–17.8 cm | 125 / 75 mm |
| 17.9–19.0 cm | 130 / 80 mm |
| 19.1–20.3 cm | 135 / 85 mm |
| 20.4–21.6 cm | 140 / 85 mm |
| 21.7–22.9 cm | 145 / 90 mm |
The ready-to-wear strap is 115 × 75 mm. For a smaller or larger wrist I make it in the right length: order your length.
What I'm asked about the TAG Heuer Carrera CAR5A8Y.FC6377
What strap size does the TAG Heuer Carrera CAR5A8Y.FC6377 take?
The TAG Heuer Carrera CAR5A8Y.FC6377 needs 20 mm between the lugs. It's the size I've been fitting on it for years.
Can the strap on the TAG Heuer Carrera CAR5A8Y.FC6377 be changed?
Yes. It has spring bars between the lugs: with the right tool the strap comes off in a minute. If you'd rather not risk a scratch, I do it in the workshop.
Can I put a leather strap on the TAG Heuer Carrera CAR5A8Y.FC6377?
Yes, in 20 mm leather. On a 45 mm chronograph I like box calf: it holds its shape and carries a substantial case.
Which strap do you recommend for the TAG Heuer Carrera CAR5A8Y.FC6377?
A 20 mm box calf. You'll find it ready in the 20 mm collection. If you'd rather have something built on your wrist, the Casati atelier.
