Overseas ultra-thin perpetual calendar – Calibre 1120 QP
The Overseas Ultra-thin Perpetual Calendar displays its technical complexity with the collection’s characteristically understated air of distinction. This timepiece houses the emblematic Calibre 1120 QP, an ultra-thin mechanical automatic movement equipped with a perpetual calendar complete with moon phases. This function calls for impressive feats of miniaturisation in order to adjust to calendar irregularities while requiring no adjustment until the year 2100, as well as to accommodate its 276 components within a space barely 4.05 mm thick. Beating a frequency of 19,800 vibrations per hour and endowed with an approximately 40-hour power reserve, the mechanism drives the hours, minutes, perpetual calendar – with day of the week, date, month and 48-month leap-year indications – as well as moon phases. The 18K white gold 41.5 mm-diameter case frames a grey dial lightly punctuated by blue accents, while the sapphire crystal caseback reveals a 22K oscillating weight adorned with a compass rose and subtle finishes.
