Thank you guys, your help is appreciated.
Now I understood 100 on the counter means 1000 shutter actuation have been made, which is about fifth of the number that requires factory overhaul.
Paul, I'm thrilled your experience with GW690 aside of your Bronica GS-1 setup. When and why did you find GW690 would be more useful/efficcient then GS-1 ?
How GW690 optics fairs against comparable in GS-1 (100mm/3.5 PG lens) for your opinion ?

I'm just trying to figure how I can benefit from owing GW690III aside of GS-1 (except of obvious 6x7 vs 6x9 film area differences)...
