• Sun-Moon Subdial – Located at the 6 o’clock position, this decorative subdial features a rotating sun and moon motif, offering a subtle celestial detail that complements the watch’s thematic design. While not a functional 24-hour indicator, it serves as a distinctive visual accent that reflects the watch’s namesake inspiration.

The leather strap conforms comfortably over time, molding to the shape of the wrist for a personalized fit. Whether paired with a tailored suit or a casual button-down shirt, the Copernicus watch adds a refined mechanical touch to any outfit. Its open-heart design also makes it a conversation starter among watch enthusiasts who appreciate visible movement architecture and the artistry of traditional horology.

Important Notes

As an automatic watch, it requires regular wear to maintain power reserve; if not worn for extended periods, it may stop and need manual winding to restart. To resume operation after prolonged inactivity, gently rotate the crown to wind the mainspring before setting the time. The leather strap should be kept away from excessive moisture to preserve its appearance and longevity. Avoid prolonged exposure to water, sweat, or humidity, as this can degrade the leather over time. For warranty details, customers are directed to click the provided warranty information link.
