ochs und junior distils the perpetual calendar into nine added parts

ochs und junior has created a Holiday Edition of its perpetual calendar, translating Ludwig Oechslin’s mechanically economical concept into a seasonal palette. The dial’s dot system shows the date, month and leap-year cycle without conventional subdials, while the entire calendar mechanism requires only nine additional and three modified components.

The 42mm case is machined from Grade 5 titanium and is rated to 100 metres. Inside is the automatic Ulysse Nardin UN-118 with 50 jewels and a stated 60-hour power reserve; the complete watch weighs 62 grams and comes on a black Ecopell leather strap. The calendar can be adjusted forwards or backwards through the crown. Pricing is CHF 15,000 excluding tax, with orders accepted through 6 January 2027.
