Seiko will release two versions of the classic watch: the Seiko Spirit Smart SCED037 (black version) and the SCED035 (grey version).
According to Gizmodo:
The most notable difference between the original 7A28-7000 and the new SCED035 (the gray model) is that it’s missing the crown and extra button on the left side of its case. It gives the watch a slightly sleeker look, and helps Seiko differentiate the re-issue from the original.
