What I'm asked about the Grand Seiko Quartz SBGX219
What strap size does the Grand Seiko Quartz SBGX219 take?
The Grand Seiko Quartz SBGX219 needs 19 mm between the lugs. It's the size I've been fitting on it for years.
Can the strap on the Grand Seiko Quartz SBGX219 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 Quartz SBGX219?
Yes, in 19 mm leather. On a 36 mm case a calf strap works every day; if you want something more, alligator.
Which strap do you recommend for the Grand Seiko Quartz SBGX219?
A 19 mm calf strap, for every day. You'll find it ready in the 19 mm collection. If you'd rather have something built on your wrist, the Casati atelier.
