Knowing the specific model of Daytona would be most helpful when requesting assistance.
But, in general, it sounds like your watchsmith installed the wrong size gasket in the tube, which might explain the difficulty in moving the stem in/out.
As for the bezel, you can often find aftermarket parts for your Daytona on ebay.
If this is a modern model, with the running seconds at the 6 o'clock subdial position, then you should search out Ziggy's reviews of the secs @ 6 Asian 7750s (hint - there is a reason your watch stops). You might also search out my 'powdered graphite' remedy, which seems to work well. However, you will need to locate a watchmaker willing to overhaul your watch (completely disassemble, clean & re-lubricate all components) prior to applying the graphite treatment (I am not accepting any new work).
