G-SHOCK announces a new lineup of heavy-duty models that are great for wear in tough environments and as street fashion items as well. The industrial design motif of these models is created by a 10-sided bezel that resembles the shape of a nut. The bezel is secured by four screws for a tough and rugged look. Combination timekeeping is provided by analog hands along with a digital display for the ultimate in operational ease. The design of the hands and the graphic figures that appear in the digital readouts create a powerful face design that enhances readability. The band connection and all buttons have checkered surfaces that prevent slipping and contribute to operational efficiency.  FEATURES Accuracy: ±15 seconds per month Approx. battery life: 7 years on CR2016 Module: 5637 Case / bezel material: Resin Resin Band Shock Resistant Mineral Glass 200m water resistant Super LED light Case / bezel material: Resin Resin Band Shock Resistant Mineral Glass 200m water resistant Super LED light Auto light switch, selectable illumination duration (1.5 seconds or 3 seconds), afterglow World time 29 time zones (48 cities + coordinated universal time), daylight saving on/off, Home city/World time city swapping 1/100-second stopwatch Measuring capacity: 99:59'59.999'' Measuring modes: Elapsed time, lap time, split time Others: Speed (0 to 1998 units/hour), Distance input (0.0 to 99.9) Countdown timer Measuring unit: 1 second Countdown range: 24 hours Countdown start time setting range: 1 minute to 24 hours (1-minute increments and 1-hour increments) Other: Auto-repeat 5 daily alarms (with 1 snooze alarm) Hourly time signal Full auto-calendar (to year 2099) 12/24-hour format Regular timekeeping Analog: 2 hands (hour, minute (hand moves every 20 seconds)), 1 dial (speed) Digital: Hour, minute, second, pm, month, date, day Accuracy: ±15 seconds per month Approx. battery life: 7 years on CR2016 Module: 5637
