G-SHOCK GST-B1000BD-2A - G-STEEL
G-SHOCK GST-B1000BD-2A - G-STEEL
A blue dial inside a black case is a combination that only works when the blue is deep enough to hold its own against the metal.
The GST-B1000BD is the dark-finished version of G-SHOCK's current G-STEEL case, with a steel bezel over a carbon-bio inner case in the line's layered guard structure, Carbon Core Guard underneath, and a solid stainless steel bracelet with a one-touch three-fold clasp.
Blue and light blue across the dial against a black bracelet, in a case 46.9 by 44.2 mm and 11.6 mm deep at 118 grams, with a screw-lock crown. Three hands, 24-hour and day sub-dials, date window, Neobrite markers. Module 5748 is Tough Solar powered and links to the CASIO WATCHES app over Bluetooth, holding fifteen seconds a month on its own. 200 m water resistant.
The blue only shows in direct light. Most of the time this reads as an all-black watch with something going on in it.
Perfect for: blue and black G-STEEL watches, dark steel bracelet watches, solar Bluetooth analog sports watches.
