Grand Seiko 5646-7020 and 5646-7010

Fascinating to compare two #GrandSeiko 5646’s that both have 9-facet cut glass crystals. On the left, the 5646-7020, and on the right, the 5646-7010. Crystal is cut much deeper on the ’20. Case, dial, hands, hour markers all different. Only the movement remains the same.
