Daylight saving gives most an extra hour of relaxation, but for one clock museum in Vista, it can be a time of stress.

The West Coast Clock and Watch Museum (WCCWM) has hundreds of clocks that need to be wound and set back an hour with the season.

Going backwards can be harmful for many antique clocks, so losing an hour actually means gaining 23, which takes even more time, said Andre Perreault with the National Association of Watch and Clock Collectors.

Perreault said the task takes about three hours.

His fellow collector, John Ginzler calls it “a nightmare.”

But the biannual chore may be done away with if Prop 7 is passed this November election.

NBC 7's Catherine Garcia explains Proposition 7, a measure deciding whether Californians will adopt year-round Daylight Saving Time or keep changing their clocks twice a year as they do now.

If Prop 7 passes, lawmakers can start discussing changes to the time change, though it doesn’t guarantee daylight saving will end. If Prop 7 fails, daylight saving will remain as is.

WCCWM on Santa Fe Avenue has various clocks that span multiple centuries.

Perreault and Ginzler are both retired and volunteer with the local chapter of the National Association of Watch and Clock Collectors.

It’s the largest clock museum on the west coast.
