It is now probably well known that Grand Seiko will be a brand of its own. This was announced at Baselworld 2017. The watches will no longer have SEIKO on the dials, instead a prominent applied GS with Grand Seiko below will sit just under the 12 o’clock marker. All the older models will be reworked with the new look. Reference numbers will change having a 2 at the beginning (e.g. SBGD001 –> SBGD201). The old ones are being phased out. Now you can see all the reworked ones at the official Grand Seiko site, check the Japan version for the complete collection:
