Jay,
Earlier in the thread you mention timing patient visits. Psychiatry or any branch of forensic medicine requires a 6-, 10-, or 12-hour totalizer for tasks ranging over 30 or 60 minutes, for which the worthy candidates are AP Royal Oak Chrono., Royal Oak Offshore, or VC Overseas. Any other specialty can probably use PP 5070, A. Lange Datograph, VC Malte Chrono, or AP Jules Audemar chrono. These choices are all great, but I can tell you after owning about 50 chronographs that just about anything else is a waste of money if you care about quality.
