This is a good condition Timex ReefGear Digital Temp Sensor watch with a Rotating Bezel with High Tide Markings. I'm not sure how that bezel would work with a purely digital watch and can't find a manual explaining it's function. The watch is fully functional and the Compass Band works and is serviceable. I am unsure as to it's water resistance rating but it is clearly a surfing / snorkeling watch based on it's look and functionality. It also has its stock mineral crystal which is odd for a 1996 Timex. The temperature sensor works as expected and the temperature graph shows the current air (or if submerged, water temperature.) I have tested it under water to check out the temperature probe but I can not attest to its water resistance and you should be aware of that before bidding.
