Grand Seiko references
9 Grand Seiko references, each one built from what Grand Seiko itself publishes about that reference — case, movement, water resistance, bracelet — with what a dealer should check before buying one.
Where Grand Seiko states nothing, these pages say so rather than filling the gap. Last reviewed 2026-09-22.
Elegance Collection
- Automatic 3-Day Power Reserve GMT, ivory dial, crocodile strapSBGM221A travel watch you cannot take near water. Crocodile leather, a splash-resistant rating, and a GMT scale printed inside the hour indexes rather than around the bezel.Specifications
- Hand-winding Mechanical, 37.3mm, off-white dialSBGW301No rotor, no automatic winding, and a crown you turn every morning. Winding a mainspring by hand is also the most informative thirty seconds of any inspection.Specifications
- 9F Quartz, 34mm, pale blue dialSBGX353Quartz, and not the kind buyers assume. Ten seconds a year, a 34mm case, 47 grams, and a water resistance rating that says splash resistant and means it.Specifications
Evolution 9 Collection
- Spring Drive 5 Days, stainless steel, blue Lake Suwa dialSLGA021One hundred and twenty hours, and a power reserve indicator you can only read by taking the watch off. Five days of reserve changes how the watch is owned and how it is inspected.Specifications
- Hi-Beat 36000 80 Hours, stainless steelSLGH005Thirty-six thousand beats an hour and eighty hours of reserve at the same time, which is the unusual part. A box crystal, a display back, and 178 grams of steel on a 40mm case.Specifications
Heritage Collection
- Automatic Spring Drive 3-Day, High-Intensity TitaniumSBGA211A Spring Drive in titanium. The seconds hand glides instead of ticking, the reserve indicator sits on the dial, and 100 grams on a 41mm watch tells you the metal is real before you check anything else.Specifications
- Automatic Spring Drive 3-Day, 62GS case, Hana-Ikada dialSBGA413The same Spring Drive calibre as the SBGA211 in a different case: 40mm rather than 41, thicker, on a box crystal instead of a dual-curved one. Identical movement, different watch.Specifications
Sport Collection
- Automatic Spring Drive 3-Day GMT, green dialSBGE295A Spring Drive GMT with a sapphire bezel insert. Sapphire does not scratch, which is the point, and chips instead, which is what you have to look for.Specifications
- Hi-Beat 36000 GMT, stainless steel, blue dialSBGJ237A large watch that publishes exactly how large it is. Fifty-point-six millimetres lug to lug and 188 grams are the two numbers that decide whether a buyer keeps it.Specifications
