High quality sports looks, back by a rich feature set, define the new SGW400 Twin Sensor from Casio. The watch takes and displays barometric pressure readings, which are then converted into Altitude measurements based on International Standard Atmospheric Values. A built-in thermo sensor gives reliable temperature readings. Combing these sensors with a rugged case design, ana-digi display and a host of additional features makes this watch tough to beat.• Twin Sensor (Altimeter/Barometer & Thermometer)• 100M Water Resistant• Low Temperature Resistant (-10C/14F)• World Time (48 cities)Attributes• Band Type:  Stainless Steel• Color:  Silver• Dial Code:  Analog and DigitalTechnical Specs• Altimeter Measuring range: -700 to 10,000m (-2,300 to 32,800ft) without reference altitude Measuring unit: 5m (20ft) Others: Reference altitude setting• Barometer Display range: 260 to 1,100 hPa (7.65 to 32.45 inHg) Display unit: 1 hPa (0.05 inHg) Barometric pressure differential pointer• Thermometer Display range: -10 to 60 C (14 to 140 F) Display unit: 0.1 C (0.2 F)• 100M Water Resistant• Low Temperature Resistant (-10 C / 14 F)• EL Backlight with Afterglow• 5 Daily alarms• Hourly time signal• World Time 31 times zones (48 cities), city code display, daylight saving on/off• 1/100 second stopwatch Measuring capacity: 23:59'59.99" Measuring modes: Elapsed time, split time, 1st-2nd place times• Countdown Timer Measuring unit: 1 second Countdown range: 1 minute to 24 hours (1-minute increments and 1-hour increments)• Full auto-calendar (pre-programmed until the year 2099)• 12/24 hour formats• Button operation tone on/off• Accuracy: /- 30 seconds per month• Battery: CR2016• Approx.
