I have had a collector of vintage dive watches contact me after reading about this project and he is thinking of offering me quite a lot of original 6309s. He is willing to offer these to me because he said he would like to help this project along, and they will all be original apart from some may have the correct flat after market hands fitted. Some it appears may need crystals or inserts. He has agreed after some hard negotiating to send me a couple of samples for me to have a look at. They will be with me soon, if any one is interested let me know.
