Watch looks great and runs. However, it will only run for a few hours before the mainspring runs out of tension. If you wind the crown a few times, you can feel the spring tension increasing. But then, at about the fifth wind, you can feel the tension release at the mainspring slips within the mainspring barrel. The end if the spring is not properly catching the inner wall of the barrel. Likely needs a mainspring replacement.The crystal is brand new. The case is in excellent condition, but the stainless steel case back is scratched up a bit. The dial and hands are gorgeous. The watch is on a black genuine leather band.Please feel free to ask questions. I have 100% positive response, so offer with confidence. Thanks for looking.
