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 Ligure Tartaruga LWT21004N
What strap size does the Ligure Tartaruga LWT21004N take?
The Ligure Tartaruga LWT21004N needs 22 mm between the lugs. It's the size I've been fitting on it for years.
Can the strap on the Ligure Tartaruga LWT21004N 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 Ligure Tartaruga LWT21004N?
Yes, in 22 mm leather, as long as you don't wear it in the water: leather doesn't like the sea or the pool. For days in the water, rubber. On a 41 mm diver I go for a full-thickness strap, not a thin one.
Which strap do you recommend for the Ligure Tartaruga LWT21004N?
Rubber if you wear it in the water; otherwise a 22 mm calf strap, full thickness. You'll find it ready in the 22 mm collection. If you'd rather have something built on your wrist, the Casati atelier.
