Okay, so I’ve been eyeing this Grand Seiko SBGH267 for a while now. It’s a beauty, no doubt, but one thing kept bugging me – the case size. I’ve got pretty average wrists, and I didn’t want something that looked like I strapped a dinner plate to my arm. So, I started digging.

First, I checked the official Grand Seiko website. They usually have all the specs listed, but sometimes it’s good to double-check, you know?
Then, I hit up some watch forums. Those guys are serious about their watches, and they usually have all sorts of measurements and comparison photos. I was hoping to find someone with similar-sized wrists who owned the SBGH267.
I even looked for some hands-on reviews from usual bloggers, I just want to get some real-world opinions.
My Findings
Here’s what I gathered:
- The official Grand Seiko website lists the case diameter as 39.5mm.
- The lug-to-lug measurement (that’s the distance from the tip of one lug to the tip of the other) is around 46.9mm, from what I could find on the forums.
- The thickness is about 13.3mm. It’s not the thinnest watch out there, but it’s not overly bulky either.
After seeing some comparison photos and reading about how it wears on different wrist sizes, I felt pretty confident that it wouldn’t be too big for me. I was concerned, and it is important for me.

So, yeah, that’s my little journey into figuring out the Grand Seiko SBGH267 case size. Hopefully, this helps someone else who’s in the same boat!
