This is the standard model, the SENSOR MASTER. I bought it for mountain climbing, but I haven't used it much, so I'm selling it. Recommended for those who don't need the high performance (and high price) of PRO TREK, Suunto, or Garmin. 【Water Resistance】 3 ATM water resistance 【Functions】 ■ German-made sensor ■ Weather forecast ■ Altimeter ■ Barometer ■ Digital compass ■ Temperature display ■ Chronograph ■ Alarm ■ Countdown timer 【Materials】 Case: ABS resin/stainless steel Belt: Polyurethane 【Size】 Case: Approx. 45x45x13mm (H x W x D) Wrist circumference: Approx. 150～220mm Weight: Approx. 57g Belt width: Approx. 22mm (Quoted from the manufacturer's HP) ●Condition It's a beautiful USED item, worn only a few times, but there is a shallow scratch from the weather mark to the top of the colon (see image 10). ※I am also listing this on other flea market sites, so I will give priority to the first person to purchase it.
