I recently picked up this beautiful little (24mm) seamaster cosmic for my wife. I thought it looked like very clean unmolested piece (without knowing much about it). Case looks clean and sharp, omega crystal, dial looks beautiful and original with an applied logo, and creamy tritium. Now other than that I know nothing about it and don't currently have a way to open it up (in through the top surgery required). I was hoping some of the gurus could hopefully provide some insight, reference number, potential movement, rough date range, etc.... I have searched and can only find info on the other tool references 105, 107, etc. I scored it for next to nothing and am not expecting it be worth much but would still like to know more about it. More importantly I think she will love it once I find a nice strap to fit on it. Thanks!!
