I am looking to sell or trade a Seamaster CK 2907. The case is stainless steel, dial original and the indices/hands are rose gold. There is a mark on the dial next to the 8, which can be seen in the pictures. The watch houses a cal 321 movement that is running strong and all chronograph functions work as they should. However, I have not had the watch serviced while in my possession. I bought it from another forum member several months ago and it is simply not getting enough wrist time. So instead of it sitting in the safe I would like to trade for something I might wear more often. I am open to offers, as long as they are vintage, in original condition and of similar value or higher. Currently I am mostly interested in sporty chronographs from the 60-70's (a nice Heuer would be a good option) or perhaps a nice Rolex 1625 Thunderbird? As far as sale, I am asking 3000 US$ net to me. Shipping in the US will be free, and anywhere else will be at cost + insurance. Happy to provide additional information and pictures to interested parties. Thanks!
