Tomony 5001-7020 is a vintage automatic diver's watch produced by Seiko in the early 1970s. It has a chrome case, black dial and stainless steel bracelet. Although it is not guaranteed to be waterproof, it was probably designed for recreational diving and has the appearance of a true Diver. This product is approximately 50 years old in today's history and still maintains its wonderful appearance on the first day. If you are interested in such products, I recommend you to consider this rare product. Professionally restored and FULLY SERVICED (the machine has been completely disassembled, every part cleaned, lubricated and adjusted for accuracy) so your watch will run smoothly with no nasty surprises.
