Straps for the Marine P0918
Selected for the 22 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 Steinhart Marine P0918
What strap size does the Steinhart Marine P0918 take?
The Steinhart Marine P0918 needs 22 mm between the lugs, usually 18 or 20 mm at the buckle. It's the size I've been fitting on it for years.
Can the strap on the Steinhart Marine P0918 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 Steinhart Marine P0918?
Yes, in 22 mm leather. On a 44 mm chronograph I like box calf: it holds its shape and carries a substantial case.
Which strap do you recommend for the Steinhart Marine P0918?
A 22 mm box calf. You'll find it ready in the 22 mm collection. If you'd rather have something built on your wrist, the Casati atelier.
