What I'm asked about the Oris Williams 01 673 7563 4754-07 4 27 01B
What strap size does the Oris Williams 01 673 7563 4754-07 4 27 01B take?
The Oris Williams 01 673 7563 4754-07 4 27 01B needs 27 mm between the lugs. It's the size I've been fitting on it for years.
Can the strap on the Oris Williams 01 673 7563 4754-07 4 27 01B 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 Oris Williams 01 673 7563 4754-07 4 27 01B?
Yes, in 27 mm leather. On a 45 mm chronograph I like box calf: it holds its shape and carries a substantial case.
Which strap do you recommend for the Oris Williams 01 673 7563 4754-07 4 27 01B?
A 27 mm box calf. 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.
