What I'm asked about the Glashütte Original Senator 1-89-02-01-05-01
What strap size does the Glashütte Original Senator 1-89-02-01-05-01 take?
The Glashütte Original Senator 1-89-02-01-05-01 needs 21 mm between the lugs. It's the size I've been fitting on it for years.
Can the strap on the Glashütte Original Senator 1-89-02-01-05-01 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 Glashütte Original Senator 1-89-02-01-05-01?
Yes, in 21 mm leather. On a 44 mm case a calf strap works every day; if you want something more, alligator.
Which strap do you recommend for the Glashütte Original Senator 1-89-02-01-05-01?
A 21 mm calf strap, for every day. You'll find it ready in the 21 mm collection. If you'd rather have something built on your wrist, the Casati atelier.
