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 SevenFriday M-Series M2/01
What strap size does the SevenFriday M-Series M2/01 take?
The SevenFriday M-Series M2/01 needs 28 mm between the lugs. It's the size I've been fitting on it for years.
Can the strap on the SevenFriday M-Series M2/01 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 SevenFriday M-Series M2/01?
Yes, in 28 mm leather. On a 47 mm case a calf strap works every day; if you want something more, alligator.
Which strap do you recommend for the SevenFriday M-Series M2/01?
A 28 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.
