With its cool simplicity and functionality, this calendar by French designer Sebastian Bergne is minimalist magnifique! It's a monthly perpetual calendar and ruler combined, utilizing only two parts: a solid beechwood base and a gear-like metal star. Match the day of the week on the star to the day of the month on the base, then advance one notch with each new day. Use the base alone as a centimeter ruler if you want to measure distance rather than time. The durable materials and ingenious design make this a timeless classic. Made in France.
