The caliber U700 used in the Promaster SST has a whooping 7 year power reserve (In pwr reserve mode) or 270 days (About 9 months) power reserve in continued use. Its got the best pwr reserve mode of any Citizen Eco-Drive watch in production today.
While I appreciate the Promaster SST for what it is, two aspects of this watch held me back from ever getting it:
1) Sheer size
2) Lack of radio controlled sync capability.
Until then, Citizen Eco-Drive watches with R/C capability (Calibers H610, U600 & U680) will do for me.
