MeisterSinger Watch Stratoscope Moon Phase ST982. Planetary feast for the eyes. The powerful, masculine case frames the unusually large moon phase display. The photorealistic image of the earth’s natural satellite corresponds to the astronomical precision with which the Stratoscope represents the moon’s various phases. The moon takes 29 days, 12 hours, 44 minutes, and 2.9 seconds to circumnavigate the earth. Most watches round this figure down to 29.5 days via the movement, which means they deviate by eight hours per year and need adjusting by one complete day every third year. However, the movement of the Stratoscope is far more accurate. Theoretically, its moon phase indicator only requires a slight adjustment after 128 years.
