I'm selling my 1990 Timex Skiathlom, in great condition and fully functional. I'm the first and only owner and it's barely been used. Thermometer and backlight still work well. No scratches on the watch face or back. New battery just installed.
The rubber watch band cracked and fell apart years ago. The elasticized band is still in great shape and still has good stretch left in it. The watch face says it's waterproof to 50m but I won't guaranty that's still true, as it's 35 years old.
Sorry, no manual or box. Please let me know if you have any questions.
