Stay on top of celestial bodies’ movements with this new ochs und Junior creation.
Ludwig Oechslin’s ochs und Junior original designs offer unique solutions to traditional complications. The ochs und Junior luna sole, a recent addition to the collection, is a testament to the brand’s commitment to a minimalist style and the simplification of astronomical indications. This new watch elegantly combines timekeeping with date, sun, moon phase, and the moon’s position in relation to the earth and sun, offering an intriguing experience.
The luna sole belongs to the ochs line collection, so it is non-customisable and is presented with two dial options – sand-blasted anthracite or white rhodium with subtle rose gold accents. Designed by Ludwig Oechslin, the 40mm round case maintains a familiar shape with its short lugs, crafted from grade 5 titanium, left untouched after milling and machining. It features a two-part construction, a screw-down crown, and boasts 100m water resistance. Remarkably slim at just 9mm, including the sapphire crystal, the watch is exceptionally lightweight, weighing only 40 grams without the strap and buckle.
In the recent Netflix series Three-Body Problem, Earth scientists required several VR game sessions powered by extraterrestrial technology to grasp the complexities of saving the planet (spoiler: it wasn’t successful). How many sessions with the luna sole watch would one need to master the intricacies of reading the moon phases with the three bodies – sun, moon, and earth depicted on the dial? Give it a try, making a note that the watch has two overlapping discs in the centre. The lower disc shows the sun as a large circle and a heart shape, while the upper disc represents the moon and is the same size as the sun. Together, these discs indicate the different phases of the moon.
The sun disc completes one rotation every 24 hours around the centre. At 12:00, it is at the top position, and at midnight, it is at the bottom. In the morning, it is at 9:00, and in the evening it is at 3:00. This allows you to determine its position in the sky at any time.
The moon operates similarly but lags behind the sun and completes one rotation roughly every 29.5 days. Its illumination can be tracked on the inner circle of the lunar ring, with a full moon appearing when the moon is opposite the sun and fully illuminated, and a new moon occurring when it is directly above the sun and completely unlit. Timekeeping, indicated by rhodium or rose gold leaf hour and minute hands, depending on the dial variant, is straightforward, as I am sure other indications will seem once you’re familiar with the display.
The intricate mechanism behind the ochs und junior luna sole watch was conceptualised by Ludwig Oechslin a decade ago and utilises a module comprising only six parts, with the base ETA 2892A2 movement operating at 28,800 vibrations/hour and offering a power reserve of 42 hours.
The ochs und Junior luna sole comes equipped with an Ecopell leather strap in Olifant, fastened with a titanium buckle also designed by Oechslin. The price is CHF 6,486 inclusive of taxes or CHF 6,000 for export price, orders are expected to be delivered within three months upon placement. For more details, please visit ochsundjunior.swiss.
