This item was purchased overseas over 20 years ago and has been stored unused in a drawer ever since. Model: DEP-8002 The watch is stopped. Is the battery dead? I have never opened it for inspection. The vinyl on the back of the watch has been slightly peeled back and re-attached, but I plan to ship it in this condition. [Included Items] Box, Instruction manual (foreign language), Warranty (expired) Although unused, it has been stored for many years, so I don't know if it will work after maintenance. Please purchase only if you understand this. I will try to explain any unclear parts with photos, etc.
