EMPEX & FIELD MESSE Multifunctional Barometer/Altimeter

This is an EMPEX multi-functional barometer, altimeter, and thermometer watch.

It's a wrist-worn electronic weather station. While it looks quite large on the wrist, it's a very light watch weighing less than 50g. I liked using it because it displays altitude changes in 1-meter increments up to 9000m. Its primary function is as an altimeter based on atmospheric pressure, so it does not have features like GPS or route logging.
It requires one CR2032 battery.
When I reinserted the battery, it accurately displayed the altitude. Although it's not strictly necessary to mention, altitude calculations based on barometric pressure in the mountains are inherently affected by pressure fluctuations, so I always used it while making manual corrections to the altitude based on known elevations.
For more details, you can search for the product name to download the manual, which is still available.
An oil compass is attached to the band, but it's not reliable. Also, the thin frame that originally protected the screen is missing. Please be aware of this.
It has been used on mountains several times and has some dirt and scratches.
This is a used item that has aged, and there may be defects. Please only purchase if you understand this.

Thank you for looking.
