What I'm asked about the Citizen Eco-Drive AW1780-25A
What strap size does the Citizen Eco-Drive AW1780-25A take?
The Citizen Eco-Drive AW1780-25A needs 21 mm between the lugs. It's the size I've been fitting on it for years.
Can the strap on the Citizen Eco-Drive AW1780-25A 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 Citizen Eco-Drive AW1780-25A?
Yes, in 21 mm leather. On a 40 mm dress watch alligator is the natural choice: thin, elegant, what it was born for.
Which strap do you recommend for the Citizen Eco-Drive AW1780-25A?
A thin 21 mm alligator. You'll find it ready in the 21 mm collection. If you'd rather have something built on your wrist, the Casati atelier.
