Claim:
A method for displaying a timekeeping product in a retail store display comprising: receiving, at a retail store, a reference time signal broadcast from a national measurement standards laboratory; continuously calibrating, at the retail store, a reference clock using the reference time signal, so that the reference clock displays a standard time-of-day as maintained by the national measurement standards laboratory; synchronizing, at a known time-of-day, the timekeeping product with the reference clock; displaying, within the retail store display, the known time-of-day at which the timekeeping product was synchronized with the reference clock; placing the synchronized timekeeping product, and the continuously calibrated reference clock, within the retail store display so that a product time-of-day displayed by the synchronized timekeeping product, and the standard time-of-day displayed by the reference clock, are visible to a retail customer at the retail store in a way by which the retail customer can visually identify a discrepancy or a lack thereof between the displayed product time-of-day of the timekeeping product and the displayed standard time-of-day of the reference clock.
