What I'm asked about the Grand Seiko Heritage SBGH343
What strap size does the Grand Seiko Heritage SBGH343 take?
The Grand Seiko Heritage SBGH343 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 Grand Seiko Heritage SBGH343 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 Grand Seiko Heritage SBGH343?
Yes, in 20 mm leather. On a 38 mm dress watch alligator is the natural choice: thin, elegant, what it was born for.
Which strap do you recommend for the Grand Seiko Heritage SBGH343?
A thin 20 mm alligator. You'll find it ready in the 20 mm collection. If you'd rather have something built on your wrist, the Casati atelier.
