Grand Seiko 2017 SBGM Automatic GMT
Seiko recently announced that in 2017 they will separate the Grand Seiko line by removing the word "Seiko" on the dial. We now have the ability to show you the new watches for 2017. All the watches in this series of posts are on the GS website and designated as new models. In many (not all) cases these are the same as earlier models but with a different dial. Perhaps if your favorite watch was sold out, or inaccessible, it will reappear now with its new livery. Happy searching!
(This does not mean the older models are gone from the catalog, but I suspect they will disappear as the inventories are sold off.)
I will freeze our Grand Seiko Master Spreadsheet at the last of the 2016 models, and at some point may create a new sheet for 2017- going forward.
