A few years ago I bought a limited edition Grand Seiko, the SBGE033 from a road show and the AD was nice enough to also give me a gift with the purchase.
It turned out to be a pair of wine glasses from Seiko with the Grand Seiko brand sandblasted onto the glass surface.
On it are three blue glass bubbles which I can't quite understand the significant of it. Tried searching it on the internet but nothing came out of the search. If anyone has any information, feel free to put it in the comment section below.
