Seiko Tomony 80-1070, Seiko's Tomony series produced in the 1970s consisted of watches that generally had hand-wound (manual-winding) mechanisms, colorful dials, interesting case shapes and sometimes themes such as cartoon characters. These watches reflected the popular culture of that period and were very popular with young users. I put a genuine iguana leather bracelet specially produced in my leather workshop on this product and it looks great. The product you are reviewing was produced in 1971. PROFESSIONAL FULL SERVICE. Since the mechanism is completely disassembled, each part is cleaned, oiled and its sensitivity is adjusted, your watch will work without any negative surprises. (It does not require maintenance for 5 years unless exposed to adverse conditions.) Product Status: Tested, all functions work.
