LeCoultre Powermatic Power Reserve Indicator Watch 1950’s
One of the drawbacks that the early automatic watches had is that you never knew how much power reserve was available in the mainspring. A manual wind watch could be fully wound and the owner would know that he had over a day’s worth of power in the mainspring to power the watch. LeCoultre’s Powerwind model solved this problem by having an aperture at the top that would give the approximately number of hours available. The color also changes to a red backround when the power falls below 12 hours.
