What I'm asked about the Nomos Glashütte Ahoi 551.S1
What strap size does the Nomos Glashütte Ahoi 551.S1 take?
The Nomos Glashütte Ahoi 551.S1 needs 20 mm between the lugs, usually 16 mm at the buckle. It's the size I've been fitting on it for years.
Can the strap on the Nomos Glashütte Ahoi 551.S1 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 Nomos Glashütte Ahoi 551.S1?
Yes, in 20 mm leather. On a 40 mm case a calf strap works every day; if you want something more, alligator.
Which strap do you recommend for the Nomos Glashütte Ahoi 551.S1?
A 20 mm calf strap, for every day. You'll find it ready in the 20 mm collection. If you'd rather have something built on your wrist, the Casati atelier.
