What length do I need?

Measure your wrist with a tailor's tape or a piece of string, comfortably snug.

15.0–16.4 cm120 / 70 mm
16.5–17.8 cm125 / 75 mm
17.9–19.0 cm130 / 80 mm
19.1–20.3 cm135 / 85 mm
20.4–21.6 cm140 / 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 IWC Pilot IW3881-06

What strap size does the IWC Pilot IW3881-06 take?

The IWC Pilot IW3881-06 needs 20 mm between the lugs, usually 16 mm at the buckle. It's the size I've been fitting on it for years.

Can the strap on the IWC Pilot IW3881-06 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 IWC Pilot IW3881-06?

Yes, in 20 mm leather. On a 41 mm chronograph I like box calf: it holds its shape and carries a substantial case.

Which strap do you recommend for the IWC Pilot IW3881-06?

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.
