‘At Fratello we love the idea that anyone can enjoy a timepiece with a beautiful complication’

For this collaboration we teamed up with our good friends from Frederique Constant. Next to the love for traditional watchmaking, we also share Dutch roots so it made perfect sense to work with Frederique Constant on creating the first unique timepiece for our new Fratello Shop. The Swiss brand with Dutch roots is based in Plan-les-Ouates, Geneva and focuses on creating exceptional timepieces of high quality and making them accessible to watch enthusiasts. At Fratello we also love the idea that anyone can enjoy a timepiece with a beautiful complication, so the Frederique Constant Classic Moonphase Manufacture Fratello Exclusive is the ideal start to a new e-commerce adventure for Fratello.

The moonphase complication

Frederique Constant<br> Moonphase Manufacture

The moonphase complication is one of the earliest known watch complications and it’s also one of the most graphical displays of time. A moonphase watch shows the current phase of the moon as you see it in the sky. As the moon travels across the sky, this is shown within an aperture display on the dial. Although astronomers define multiple phases of the appearance of the moon throughout its cycle, there are four main phases mostly used to describe the position of the moon as seen from earth.

A ‘new moon’ occurs when the moon and sun are in alignment on the same side of the Earth and therefore there is no moon visible to us. As the moon travels through the sky during its monthly orbit, more of its surface becomes illuminated by the sun. The second phase is known as the ‘first quarter’ and this is when the right-hand side of the moon is lit by the sunlight. The next phase is known as the ‘full moon’ and this occurs when the entire moon surface glows. The final phase is called the ‘last quarter’ and the left-hand side of the moon is visible until the cycle begins again and returns to a new moon.

So, how does it work? A lunar month has 29 days and 12 hours. The disc displaying the moonphases actually has two moons on its surface. A mechanical, co-axially mounted finger advances this 59-tooth moonphase disc once per day. Therefore, after 29.5 days, the disc completes the lunar month cycle and the second moonphase appears on the dial as the total number of teeth is 29.5 x 2 = 59. This also means that one needs to perform a one-day correction on the moonphase every two years and 7.5 months. With this Frederique Constant Classic Moonphase Manufacture Fratello Exclusive that’s an easy thing to do as all corrections for time, date and the moonphase are done via the crown.

Why buy this watch?

A moon phase was one of the first complications that I ever saw on a wristwatch. I was just a kid and our neighbour showed us his new watch, with a moon phase on the dial. It was like magic to me. Only much later, I understood the complexity of a moonphase display on a (mechanical) watch. But aside from what it takes to develop this complication for a wristwatch, I simply love the idea of having something beautiful like the moon on a dial. The moon is something magical to me, and every time there’s full moon I observe it for a few minutes from our apartment’s window. And whenever my little daughter is still awake, she often comes up to me and I will pick her up so we can admire the moon together. These moments are so precious to me. The grey anthracite dial of this Frederique Constant Classic Moonphase Manufacture combined with the blue moon phase disc, looks as peaceful as the real moon does during a starry night. Frederique Constant is able to offer a watch with this beautiful complication using an in-house developed and in-house assembled movement, for a very fair price. The moonphase remains to be one of my favourite complications for a watch, not in the last place because it reminds me of those wonderful and peaceful moments at home observing the full moon.

The Frederique Constant Classic Moonphase Manufacture Fratello Exclusive is produced in a limited run of 29 pieces and is available exclusively in the Fratello Shop. They are all individually numbered on the caseback. For the images of this page, we used the prototype, which doesn’t show a number. All watches will ship immediately with free delivery.

The watch

The 42mm 3 parts-case holds a convex sapphire crystal and see-through caseback revealing the inner workings of the FC-712 caliber. The two counters of the moonphase and date are respectively located at three and nine o’clock. The elegant curved dial merges seamlessly with the case and features printed roman numeral indexes and hand-polished hands. Finally, the blue crocodile leather strap completes the look.


The Frederique Constant Classic Moonphase Manufacture Fratello Exclusive is powered by the in-house developed calibre FC-712 automatic movement with 38 hours of power reserve. Based on the iconic FC-700 movement series from Frederique Constant, it has been redesigned in order to split the moonphase and date into two counters. Both functions are adjustable via the crown. Through the transparent caseback, the movement shows off the famous Perlage and circular Côtes de Genève decorations present on all Frederique Constant in-house calibers.
