This watch embodies the poetic cycle of time, where months and days rotate endlessly and seconds flow continuously.
Case:
41mm diameter, 12.9mm thickness. Features a stepped round case design with sculpted lugs and a grooved caseback. The entire case is finely polished, delivering a refined metallic texture and strong sense of depth.
