Grand Seiko | SBGM023

The SBGM023 has a vintage inspired case and subtle matte grey dial. The case has a classic round profile with open-hole lugs and water resistant crown. It's double domed sapphire crystal replicates the high curve of a vintage plastic crystal but with the scratch resistance of modern sapphire. The in-house caliber 9R66 features a GMT hand for displaying your home time and a quick-set jump hour hand for easily adjusting your travel time. The satin stainless steel bracelet has polished sides and each link pivots on a live axle for longevity. Like all Grand Seiko's the SBGM021 is meticulously adjusted to chronometer standards tighter than C.O.S.C. - IN STOCK
