In this video I attempt to restore an iconic digital watch from 1978. The Seiko M158-5000 or Pan Am as it was nicknamed . Was the first digital GMT watch and favoured by pilots for its ability to track 3 time zones and day/dates . A must have watch for digital collectors. Watch to find out if I can repair this one!

Nice to see someone who's into these early digitals. I love LED watches, recently bought a beat up Rado LCD on eBay...
We have the Seiko quartztester QT-99 at my work. Still use it almost every day. We also have the instructions too. I can send you some photos of the instructions if you need them.
