Seiko Astron #SSH123J1 not only uses Seiko’s very latest GPS Solar calibre 5X53 but has a dial with a radial pattern that echoes the explosive power of a supernova. #SSH123J1 is sleek and sophisticated, with its thickness of 12.2mm, diameter of 43.5mm, and lug-to-lug of 48mm. The hands and indexes are coated with a layer of Lumibrite to ensure that Astron’s exceptional timekeeping precision can be enjoyed even in low light conditions. #seiko #seikophilippines #gpssolar #seikoastron #astron #limitededition #supernova #gpssolarmovement #seikowatches #dailywatches
