The Seiko Ananta Spring Drive Moon Phase watch (reference SNR023/SNR023J1) was unveiled during Basel-world 2010.
The Spring Drive Moon Phase watch perfectly and precisely captures the beauty of the moon’s orbit in glide motion. The natural flow of time is measured to an accuracy of one-second-a-day by SEIKO’s unique Spring Drive technology, while the glide motion of the hands perfectly represents the continuous, silent and graceful orbit of the planets.
This timepiece comes with a stainless steel case and bracelet. Measuring 46mm diameter, the watch houses the Seiko Caliber 5R67 Spring Drive movement. Visible through the sapphire crystal case-back, this caliber provides a power reserve of 72 hours.
The black dial features polished steel indices, central hour, minute and seconds hands, power reserve indicator and moon-phase display with black moon on the silver disc.
Note: In the Japan domestic market, this model was launched in September 2010 as Seiko Brightz Ananta Spring Drive Moonphase with reference number SAEA011. The retail price of Seiko SAEA011 is 472,500 yen (450,000 yen without tax).

About Seiko Ananta collection
Introduced in 2009 for the global market, Seiko Ananta is an exclusive range of luxury timepieces with Spring Drive and high-grade mechanical movements. In 2010, new models joined the Ananta series: the Spring Drive Moon Phase, the Spring Drive Chronograph (reference SPS011) and a new Automatic Chronograph with Caliber 8R28 (reference SRQ009).
Katana is the centuries-old art of sword-making, which combines great handcraft skills with the highest technology. Precision, artistry, parabolic curves and sharpness of Katana all find expression in the Ananta collection. The side of the case has the distinctive Katana curve and a three-stage ‘blade’ polishing process gives the case its remarkable mirror finish, as smooth and flat as a Katana sword. The sharpness of the hands and dial markers reflects the razor edge of the blade and the precision of the steel work in the Katana sword is mirrored in the high accuracy of the mechanical and Spring Drive movements.
