The Ochs und Junior Ochs Line Moon Phase or Selene watch is a unique timepiece that stands out in the horological world. Designed by Ludwig Oechslin, the watch is not just a time-telling device but also an astronomical marvel that accurately displays the phases of the moon. The watch, available in an exclusive Ochs blue with rhodium-plated markers, hour, and minute hands, and full moon, is celebrated for its precision. It calculates the lunar cycle as 29.5306122449 days, ensuring the correct length of the moon phases for an impressive 3,478.27 years before it deviates by a single day. This level of accuracy is rarely seen in the industry, making the Ochs Line Moon Phase or Selene a truly remarkable piece of craftsmanship.

Design Philosophy

Simplicity and Functionality

Ludwig Oechslin’s approach to watchmaking is rooted in simplicity. He believes in the principle of ‘less is more’, which is evident in the design of the Ochs Line Selene. While a typical moon phase complication comprises numerous pieces, the Ochs Line Selene requires only five additional parts. This minimalist design philosophy doesn’t compromise the watch’s functionality or precision. Instead, it enhances the watch’s aesthetic appeal and makes it a masterpiece of minimalist design.

Pricing and Availability

Accessible Innovation

The Ochs Line Moon Phase or Selene watch is priced at CHF 5,500 (including 7.7% Swiss VAT) or CHF 5,077 for export. This pricing strategy aligns with Oechslin’s goal of making innovative timekeeping accessible to a wider audience. The watch comes with an estimated shipping time of 12-16 weeks, ensuring that customers receive their timepiece in a timely manner.

Functionality Overview

Unique Features and Display

The Ochs Line Moon Phase or Selene watch is more than just a timepiece. It’s a functional work of art that displays the time, date, and phases of the moon. The moon phase function is visually intuitive, with the center of the dial representing the Earth, the large dot at 12 o’clock symbolizing the Sun, and the full moon depicted when the moon is opposite the Sun and Earth at 6 o’clock. The new moon is represented by a dark circle at 6 o’clock when the moon is between the Sun and the Earth at 12 o’clock. This unique display of moon phases is a feature that sets the Ochs Line Moon Phase or Selene watch apart from other timepieces, such as the 2023 Hermes Arceau Petite Lune watch.


Precision and Craftsmanship

The Ochs Line Moon Phase or Selene watch is a testament to Ludwig Oechslin’s mechanical genius. The watch features an epicyclic gear system that drives the lunar disk beneath the dial counter-clockwise. This system ensures a highly precise moon phase calculation that will be accurate for 3,478.27 years before it deviates by a single day. This level of precision is a testament to Oechslin’s commitment to creating timepieces that are not just aesthetically pleasing but also mechanically superior.
