YES World 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 analog, 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.
