The sum of 40 years of watchmaking experience, Dr. Ludwig Oechslin’s new perpetual calendar watch is designed for everyday use. The year, month and date are displayed with analog dots to address a key usability challenge with calendar watches: making the date legible, without resorting to an oversized display which distracts from reading the time.
ochs und junior expects to manufacture about 20 perpetual calendar watches this year. The case is manufactured by Peter Cantieni in Hinwil, Switzerland, while the gear system, dial, hands, buckle and crown are manufactured by Helfenstein in Alpnach, Switzerland. Each perpetual calendar is hand-assembled and hand-regulated by Sandra Flück at the ochs und junior workshop in Lucerne.
Perpetual calendars can be a laborious affair to set. Most require a complex system of pushers, and the date cannot be adjusted backwards. Oechslin’s perpetual calendar can be set simply using the crown, and the date is adjustable both forwards and backwards
The perpetual calendar function comprises just 9 additional parts. Fewer parts mean fewer interactions between parts and higher reliability. A lifetime warranty covers all parts designed by Oechslin.
Every function can be set simply using the crown, and the date can be adjusted forwards and backwards. You can also customize your personal perpetual calendar. Online or in person.
