Seiko SBTM321. This watch is radio controlled and solar powered meaning it will run and be on time for years as long as it gets light. Condition is excellent and there are very small scratches on a couple links as this was worn for maybe 5 days since it was bought new. Selling because I have too many watches and just don’t wear it enough. Comes with box papers and all links. Feel free to ask any questions
