Seiko's HGK001P1 is now confirmed live on Seiko Singapore at SGD 626.80 (~$489), part of a "Conceptual Regular" sub-collection. It gets the 8T63 caliber, a 40 mm case, and a champagne dial. The "P1" suffix seems to be regional, and it slots the watch into a house sub-collection called "Conceptual Regular." Interestingly, this categorization didn't show up anywhere in the Philippines or US listings we found for the base HGK001. Between the US retailer figure (~$440), the Philippines listing (~$497), and now Singapore (~$489), the HGK001/HGK001P1 pair lands in a fairly tight band once everything's converted to a common currency.
