Vacheron Constantin Overseas Ultra-Thin Perpetual Calendar Pink Gold, Caliber 1120 QP/1

Unveiled at SIHH 2018 in a pink gold case edition, the new Overseas ultra-thin perpetual calendar is one of the slimmest on the market houses the iconic Vacheron Constantin Caliber 1120 QP/1, an ultra-thin mechanical self-winding movement powering perpetual calendar and moon-phase indications. The 4.05 mm thick ultra-slim movement comprising 276 parts keeps track of calendar irregularities with no need for correction until 2100.

Beating at a frequency of 2.5 Hz and endowed with an approximately 40-hour power reserve, it drives the hours and minutes, perpetual calendar – day of the week, date, month and leap year on a 48-month counter – as well as moon-phase functions.

Its 18 carats 5N pink gold case, measuring 41.5 mm in diameter and water-resistant to 50 metres, frames a translucent silver-toned lacquered dial punctuated by 18 carats gold hands and hour-markers highlighted with luminescent material, while the transparent sapphire crystal caseback reveals a 22 carats oscillating weight adorned with a wind rose.

Secured by an interchangeable 18 carats 5N pink gold folding clasp, the equally interchangeable dark blue alligator or rubber straps provide an extremely chic way of accentuating the refinement of this model.
