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 |

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 Vacheron Constantin Harmony 5100S/000P-B056
What strap size does the Vacheron Constantin Harmony 5100S/000P-B056 take?
The Vacheron Constantin Harmony 5100S/000P-B056 needs 18 mm between the lugs. It's the size I've been fitting on it for years.
Can the strap on the Vacheron Constantin Harmony 5100S/000P-B056 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 Vacheron Constantin Harmony 5100S/000P-B056?
Yes, in 18 mm leather. On a 42 mm chronograph I like box calf: it holds its shape and carries a substantial case.
Which strap do you recommend for the Vacheron Constantin Harmony 5100S/000P-B056?
A 18 mm box calf. You'll find it ready in the 18 mm collection. If you'd rather have something built on your wrist, the Casati atelier.
