Flawless on dial and hands with original lume. Case size is 40mm. Movement service history unknown but is keeping time, chronograph and day date quickset function works as intended. Top chrono button is a tad sticky but just rebound slower than normal, otherwise it start/stop/reset with no problem. Features the JDM 6139A with 21 jewel counts instead of 17 jewels for international models. The 6139-7012 reference along with the numeral dial variant is often refer to as the military dials as the watch has been commissioned by the Japan Air Self Defence Force (JASDF) in the 70s. The commissioned model has the JASDF logo featured on the caseback. The bracelet that’s paired with this watch is one I got off of a 6139-8020 and trimmed down to fit 19mm. (It was from my early Seiko Bruce Lee hunting days) I’m looking for $475usd obo shipped within Canada or CONUS. Payment method is PayPal F&F in USD only (or direct e-transfer if you’re in Canada). I have sold a few watches on here and can provide reference. The watch and myself are located in Vancouver Canada. Thanks for looking.
