What length do I need?
Measure your wrist with a tailor's tape or a piece of string, comfortably snug.

|---|---|
| 15.0–16.4 cm | 120 / 70 mm |
| 16.5–17.8 cm | 125 / 75 mm |
| 17.9–19.0 cm | 130 / 80 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 Rolex Pearlmaster 81158
What strap size does the Rolex Pearlmaster 81158 take?
The Rolex Pearlmaster 81158 needs 17 mm between the lugs. It's the size I've been fitting on it for years.
Can the strap on the Rolex Pearlmaster 81158 be changed?
Yes, and easily: the lugs are drilled, so the spring bar is pushed out from the outside with a thin pin, without opening anything. If you prefer, I do it in the workshop.
Can I put a leather strap on the Rolex Pearlmaster 81158?
Yes, in 17 mm leather. On a 34 mm case a calf strap works every day; if you want something more, alligator.
Which strap do you recommend for the Rolex Pearlmaster 81158?
A 17 mm calf strap, for every day. I don't keep this size ready in the catalogue: I make it to measure. If you'd rather have something built on your wrist, the Casati atelier.
