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

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 Otsuka Lotec No.8
What strap size does the Otsuka Lotec No.8 take?
The Otsuka Lotec No.8 needs 24 mm between the lugs, usually 20 mm at the buckle. It's the size I've been fitting on it for years.
Can the strap on the Otsuka Lotec No.8 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 Otsuka Lotec No.8?
Yes, in 24 mm leather. On a 31 mm case a calf strap works every day; if you want something more, alligator.
Which strap do you recommend for the Otsuka Lotec No.8?
A 24 mm calf strap, for every day. You'll find it ready in the 24 mm collection. If you'd rather have something built on your wrist, the Casati atelier.
