What I'm asked about the Sinn Instrument Chronographs 900.011
What strap size does the Sinn Instrument Chronographs 900.011 take?
The Sinn Instrument Chronographs 900.011 needs 22 mm between the lugs. It's the size I've been fitting on it for years.
Can the strap on the Sinn Instrument Chronographs 900.011 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 Sinn Instrument Chronographs 900.011?
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 Sinn Instrument Chronographs 900.011?
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.
