How many metal parts are in a Swatch (more accurate and reliable than a Rolex - under normal broad operating conditions and environment.) Let's get sensible about design criteria and choices for material selection. Just because metal is used doesn't mean that it was objectively the best for the required application. Engineers aren't the only discipline involved the materials choice. - -----Original Message----- From: DonjR43198@aol.com [mailto:DonjR43198@aol.com] Sent: Thursday, October 21, 1999 11:03 AM To: leica-users@mejac.palo-alto.ca.us Subject: Re: [Leica] Re: judicious use of plastics In a message dated 10/21/99 10:51:36 AM Central Daylight Time, bdcolen@earthlink.net writes: << Doug - When the NEXT Millenium dawns and archeologists are going through our garbage dumps, they will find infinitely more perfectly preserved plastic products and product parts than they will metal ones.

How many parts in the working parts of a Rolex are made of plastic?
