Ochs & Junior: Perpetual

This watch is inspired by the Ochs & Junior "Perpetual Calendar" watch. Dr Ludwig Oechslin's perpetual calendar watch is designed for everyday use. The 4 perforations in the month disk indicate the month, and also show whether it is a leap year or a common year. When the outermost dot is orange, it is a leap year (366 days), but when it is dark, it is a common year (365 days). The small circle beneath 12 o'clock is the power reserve indicator - the disk rotates counterclockwise. Just above the 6 o'clock marker is a seconds disk with a milled excentric dot, which shows the watch is running.
