The only problems are that capacitors, if that's what they are using tend to go south after about 20 years unless they are non electrolytic and very well encapsulated (Glass). Rechargable batteries tend to loose their rechargability after a few years. Also, seals and gaskets tend to degenerate chemically. The ideal watch of this type would have the best cap money can buy with enough buffer charge to keep the thing alive for 1 day with a full charge, and a rugged low friction movement that lasts and lasts. Adjustments would have to be accomplished via some sort of inductive method such as an iron core being introduced the area where the winding stem usually. This could be left on all the time and could have the appearance of a normal crown. It would not penetrate the watch's movemrnt boundary though. Another approach would involve having 1 or 2 contacts that would penetrate the boundary but would be sealed using a mfg process similar to that used for sealing contact on vacuum tubes and light bulbs! When was the last time one of those leaked?????? Tubes from the 20s and 30s are still holding their vacuums today Ditto for light bulbs. The last factor would be the sealing of the glass around the stainless steel cushion. I don't believe this would be a problem and the watch might be vacuum packed with a little gadget viewable through the glass that pops or turns colours if air ever gets in. BTW: +-14.1 PSI is irrelevant 500 meters down just 1 more ATM. The only problem remaining would be the clumsiness of time changes for frequent travelers For them there would be several solutions 1 Keep the watch at GMT and quit bitching 2 Keep the GMT Master and quit bitching See Ya Javier Krechtz@aol.com wrote: > In a message dated 9/15/00 9:24:37 PM Eastern Daylight Time, > summarex@yahoo.com writes: > > << Hi > The Kinematic is a Quartz watch with a capacitor or battery that gets > recharged > by a little generator that's turned with wrist movement.
