The YES watch philosophy is that time is more than just 365 days in a year, 24 hours in a day, 60 minutes in an hour and 60 seconds in a minute.

YES watches combine the daily and seasonal cycles of the sun and the moon, with the steady beat of hours, minutes and seconds. At a glance, your YES watch will tell you times for sunrise and sunset, for moonrise and moonset, lunar phase and percent illumination, as well as analogue, digital and military time for wherever you are on the planet. YES watches also alert you to solstices, equinoxes, and cross-quarters, and predict time and date for the next new and full moons through the year 2099. YES wrist watches are programmed for nearly 600 cities worldwide, automatically adjust for daylight saving time, and keep time in AM/PM or 2400 format.
