One of the most popular range of Seiko watches are the Seiko Perpetual Calendar watches. They are Kinetic (i.e. no need to ever change battery) and are part of either the Premier or the Arctura range of watches. One of the star features of these watches is the Auto-relay system: which means when the watch senses 24 hours of inactivity it will go to sleep. It can sleep up to 4 years! when it is sleeping, the hands do not move but the date moves. This way the watch can save and store the energy. When you shake the watch, it will wake up and adjust automatically to the correct time. It is such a pleasant sight to just see this mechanism in action!
Seiko Perpetual watches are the ideal choice for dress watches. They look great and the functionality and technology is top-notch!
