Fossil JR-9886 Sundial

Today's watch is one that you need a sunny day and a compass to read.
The watch is by American brand Fossil from 1998, and may have been a limited release. The watches model number is JR-9886.
The watch is a normal sundial, with metal base, plastic gnomon (the part that casts the shadow), and leather strap. To tell the time, you need to find some sun, align the watch to right orientation with a compass, and see where the shadow lies.
The watch will run indefinitely, and is water resistant to as deep as you want ;-).
Unfortunately, due to needing the sun (and a compass) to tell the time, it's use is rather limited, so if you need to tell the time indoors, at night, on a cloudy day etc. then this is not a watch for you!
