What length do I need?

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 Oris Aquis 01 400 7777 7155-Set

What strap size does the Oris Aquis 01 400 7777 7155-Set take?

The Oris Aquis 01 400 7777 7155-Set needs 26 mm between the lugs. It's the size I've been fitting on it for years.

Can the strap on the Oris Aquis 01 400 7777 7155-Set 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 Aquis 01 400 7777 7155-Set?

Yes, in 26 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 50 mm diver I go for a full-thickness strap, not a thin one. I don't keep rubber ready in 26 mm: write to me and I'll make it.

Which strap do you recommend for the Oris Aquis 01 400 7777 7155-Set?

Rubber if you wear it in the water; otherwise a 26 mm calf strap, full thickness. You'll find it ready in the 26 mm collection. If you'd rather have something built on your wrist, the Casati atelier.
