What I'm asked about the Grand Seiko Heritage SBGH301
What strap size does the Grand Seiko Heritage SBGH301 take?
The Grand Seiko Heritage SBGH301 needs 19 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 SBGH301 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 SBGH301?
Yes, in 19 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 Grand Seiko Heritage SBGH301?
A thin 19 mm alligator. You'll find it ready in the 19 mm collection. If you'd rather have something built on your wrist, the Casati atelier.
