1 This is a Soviet Era Mitron watch marked MITRON CCCP Quartz 3 ATM.  It worked until the battery died.  The buyer will need to have a new battery installed.  Sold as is.  Bought this on the Cambodian Border when the Khmer Rouge was considered an insurgency.  I paid a hefty price for it at the time.  Never used it but it is a unique piece. Sold as is! Feel free to ask questions, know before you buy!
