The movement in detail
The anno’s calendar first has to be learned. Around the perimeter are 31 date holes, with separate groups for seven weekdays and twelve months. Coloured-dot positions replace abbreviations in a wearer’s language. Some will see an extra task; an enthusiast for analogue interfaces may find it the main pleasure.
Ludwig Oechslin builds the calendar function around gears and very few special elements. Indications are placed directly on working components. The appeal is engineering economy: complexity is reduced at the construction level. That does not promise immunity to faults, but it makes the mechanism’s logic easier to see and understand.

© © ochs und junior · SourceAn annual calendar distinguishes 30- and 31-day months. February requires manual correction on March 1, and stopping means restoring the settings. The ETA 2824-2 base provides 38 hours of reserve, so an anno left off over a weekend may stop. This matters more in practice than the attractive phrase “one correction a year.”
The Grade 5 titanium case measures 42 × 11 mm, with stated 100 m water resistance. The shop lists variants at CHF5,488.20 including Swiss VAT at 8.1%, or CHF5,077 for export, with readiness estimated at two months. Import costs are additional. Our interest is the original calendar and functional finishing, provided you welcome replacing lettering with a learned visual habit.
