A lot of watch and a superb piece of kit the Crystal is superb with AR coating it appears as if it isn't there which also makes the Dive chrono very difficult to photograph.Diameter is around 41MM without the Chronograph buttons which are all of the screw in variety.Even if you do not bond with it You will have no trouble in selling it on.I bought Mine from the superb Neil from Chronomaster.Let Us know if You do take it in a trade.
