The GSTB400CD-1A3JF has a bezel with a new green ion-plated (IP) finish, which brings out the texture of the metal. The slim GSTB400 design is made possible by advances in component miniaturization and thinning of its modules, without sacrificing any Bluetooth or solar functions. Power consumption has also been significantly reduced. In terms of design, the number of button guards has been reduced as much as possible, enabling the use of large stainless steel buttons that are slim yet easy to operate. The top bezel has been given five different finishes, while the middle bezel has been given four different finishes, which creates an elegant effect and changes the appearance of the texture of the metal depending on the viewing angle SPECIFICATIONS Case / bezel material: Resin / Stainless steel One-touch 3-fold Clasp Stainless Steel Band Solid Band Mineral Glass Neobrite Shock Resistant Carbon Core Guard structure Green ion plated bezel 200-meter water resistance Shock resistant (G-SHOCK) Tough Solar (Solar powered) Double LED light LED light for the face (Super illuminator, selectable illumination duration (1.5 seconds or 3 seconds), afterglow) LED backlight for the digital display (Super illuminator, selectable illumination duration (1.5 seconds or 3 seconds),afterglow) Mobile link (Wireless linking using Bluetooth ) Hand shift feature (Hands move out of the way to provide an unobstructed view of digital display contents) World time 38 time zones (38 cities + coordinated universal time), city code display, city name display, daylight saving on/off, auto summer time (DST) switching, Home city/World time city swapping 1/100-second stopwatch Measuring capacity: 00'00''00~59'59''99 (for the first 60 minutes) 1:00'00~23:59'59 (after 60 minutes) Measuring unit: 1/100 second (for the first 60 minutes) 1 second (after 60 minutes) Measuring modes: Elapsed time, lap/split time Countdown timer Measuring unit: 1 second Countdown range: 60 minutes Countdown start time setting range: 1 second to 60 minutes (1-second increments and 1-minute increments) 5 daily alarms Hourly time signal Battery level indicator Power Saving (display goes blank to save power when the watch is left in the dark) Full auto-calendar (to year 2099) 12/24-hour format Button operation tone on/off Date/month display swapping Day display (days of the week selectable in six languages) Regular timekeeping Analog: 2 hands (Hour, minute (hand moves every 20 seconds)) 1 dial (battery level, mode) Digital: Hour, minute, second, pm, month, date, day Accuracy: ±15 seconds per month (with no mobile link function) Approx. battery operating time: 7 months on rechargeable battery (operation period with normal use without exposure to light after charge) 18 months on rechargeable battery (operation period when stored in total darkness with the power save function on after full charge) Size of case : 46.6×49.6×12.9mm Total weight : 160g
