Seiko 5 Moon-Phase 6347-5000






This Moonphase model boasts a Genta-esque octagonal case with a stepped bezel, but the standout feature is undeniably its dial. Up close, the dial offers an experience akin to stargazing.


Its three-dimensional design is enhanced by the recessed dial, a fluted ring with a glittery stardust effect, and a sunken moon-phase window, all of which contribute to a deeply immersive appearance. The gold-polished elements not only enhance the dial’s overall aesthetic but also ensure excellent legibility.


Powered by the Cal. 6347A, the watch allows you to fast-forward the date or adjust the moon phase with a single pull of the crown while pulling it two steps lets you set the time.


After we've had a lot of interest in the previous example we sold almost a year ago, today we're offering a mint example complemented by its very rare original box.
