Completely untrue. A properly serviced mechanical watch movement (providing the original design is sound) is a very robust piece of micro-machinery. I collect vintage Gruen watches and one dress watch I wear quite often is a 70-year-old 17 jewel Gruen Veri-Thin. It was serviced last year, keeps excellent time (on par with some of my much, much newer Rolexes), and looks like a million bucks. Here is one of my pocket watches, a Gruen VeriThin Louis XIV in green gold that is over 80 years old. The movement is a chronometer grade 17 jewel with a swan's neck regulator.
