I'll try to describe it as best as possible, whenI unscrew the crown and try to pull it out a bit it sort of click when I wind the watch and it does'nt turn smoothly when adjusting the date or setting the watch. I have had one of the subs longer than the other and the problem has gotten worse. I am new to collecting and purchased these watches from King. I just wear them straight away from purchase. I have read about guys that have them serviced before useing. Also have there watches modded. I haven't done that to any of my reps. I have a bunch of Canal St reps that still work fine. That how I got interested in collecting. I have one gen a two tone blue face sub I purchased last summer in Grand Caynman Island at Kirks Freeport. any help would be appricated
