Limited editions are supposed to be just that, limited. Though for Frederique Constant, limited edition doesn’t necessarily mean limited to just one run, because to open 2024 they’ve decided to do a third run of the 2022 Slimline Perpetual Calendar Manufacture.
Perpetual calendars are perhaps the peak of horology simply because of the technical prowess they display. However, not all perpetual calendars are created equal and often what separates the good from the bad is legibility. How do you get across so much information without overwhelming people or oversimplifying? Here the Slimline Perpetual Calendar excels with a highly legible dial whose skeletonization doesn’t actually hurt legibility for once.
The focus is on the weekday and date ring at 9 and 3 o’clock respectively, the two components wearers would use with some regularity. A smaller sub-dial displays the months at 12 o’clock. Frederique Constant have even considered how to represent leap years subtly, with the dot representing February turning red when the extra day is set to arrive. Amongst all that they’ve still managed to fit a moonphase display at 6 o’clock.
With a 42mm diameter paired with a fairly thin bezel and case, the dial has plenty of room to breathe. Other dimensions include 47mm lug-to-lug and 12.05mm in height.
Through the sapphire display caseback you can see the in-house calibre FC-775 with an anthracite-coated bridge and blue skeletonised rotor. It beats at 4Hz and has a 38-hour power reserve, so not weekend proof, but certainly up to the task of a daily wearer.
What separates this run from the previous two runs of the Slimline Perpetual Calendar Manufacture? The first 99-piece run was decked out in brown and blue accents, while the next run was a black-on-black PVD version limited to 35 pieces. This run is limited to 135 pieces adorned in a smoky grey palette. Not quite fifty shades of grey, but certainly close to it.
These will be available from March 2024 at the Citizen Flagship Store in New York and select Frederique Constant retailers with prices starting at $11,995 USD.
