Product Details

Vintage Seiko 6139-6005 automatic chronograph in honest, wearable condition. Recently serviced by a well-known independent watchmaker: movement disassembled, cleaned, inspected, lubricated, and adjusted as needed. At time of service, running approx. -4s/day with strong amplitude and low beat error, though performance may vary. Original dial and handset with attractive patina and nicely faded “Pepsi” tachymeter bezel adding great vintage character. Crystal cleaned/polished and presents well. Case remains thick with normal wear and light marks consistent with age. Chronograph functions and resets as expected during testing. Day/date quickset working. Fitted on a full link Uncle bracelet. Please note: vintage watch with age-related wear and prior corrosion addressed during service. Work focused on function, not cosmetic restoration. No guarantees on long-term accuracy or water resistance. Sold as-is. Additional photos and service info available upon request.
