I've managed to bag a complete example of this watch - I've been searching for one for ages so you can imagine my joy when I won this on the bay (a lot cheaper than I've seen them go for before).
The watch was advertised as fully working however when it arrived I noticed that the "mode" button that operates the chrono function did not work. Obviously I can return to the seller and get a refund; however I thought I would see if any of you guys think that this is repairable. I've had the back off and everything looks ok but I know nothing about digital movements. The contact for the button is attached and clean and looks just like the contact for the "date" button (which works).
My thinking is if I can get a discount I might keep it and get it repaired. If not it will go back and I will continue the search.
