S.U.F Helsinki’s moonphase watches are timepieces that bring the touch of Stepan Sarpaneva’s trademark elegance and aesthetic with displays and dials that track the phases and ever-changing beauty of our beloved neighbor in the sky. Moonphase watches have served both practical and artistic purposes throughout history: aiding humanity in navigation and celestial observations, fulfilling our species’ innate curiosity, thrive for exploration and search for deeper meanings in the order of nature.

Moonphase display is a popular complication, often found in luxury and high-end watches, which accurately depicts the different phases of our home planet's moon; the new moon, waxing crescent, first quarter, waxing gibbous, full moon, waning gibbous, third quarter, and waning crescent.

The moonphase complication is based on a mechanism that is calibrated to replicate the lunar cycle, which takes approximately 29.5 days to complete. The mechanism is synchronized with the natural lunar cycle, ensuring the accuracy of the moonphase display with varying visual details and intricacies.

Moonphase watches serve both practical and aesthetic purposes. Historically, they were used by sailors and astronomers to determine the tides and plan celestial observations. In the modern day they are cherished as luxury timepieces and symbols of sophistication, which is the standard for our craftsmanship.

Every S.U.F moonphase model is created with distinguishable artistry and poetic touch, fitting especially for ones who have an appreciation for astronomy, detailed watchmaking and have a fascination with the moon and its symbolism.
