The Parmigiani Fleurier Centum Perpetual Calendar Openworked Graphite is an open-dial version of Parmigiani’s existing Centum Perpetual Calendar. This isn’t an openworked swiss replica watch in the traditional sense of that term – openworking, or skeletonizing, is the removal of material from the movement of a replica watch in order to create a sense of transparency. Like this. The Centum Perpetual Openworked, on the other hand, has a transparent, tinted dial that lets you see some of the mechanisms driving the perpetual calendar as well as the moonphase disk.
Parmigiani men’s replica version of the Centum Perpetual is mechanically identical to this replica watch, and, the Tonda case, streamlined lugs, and Geneva (Fleurier) striped dial notwithstanding, it comes across as a quite traditional implementation of a perpetual calendar. The retrograde date indication and double moonphase are well integrated into the overall design and it’s a pleasantly harmonious, technically interesting wristreplica watch.
The Openworked version on the other hand is quite a bit more overtly visually engaging and has a cooler, rather more modern vibe than the original, it’s being offered only in white gold, in a 42mm x 11.15mm case, and the palette of greys, pale blues, and blacks gives it a visual clarity that plays well against the traditionalist feel of a perpetual calendar complication. Interestingly enough, despite the fact that you can see so many of the perpetual calendar components, the Openworked doesn’t seem visually cluttered at all in comparison with the existing model; the blue tint given to the dial as well as the close range of colors does a lot to keep all the visual elements well integrated.
As with the original Centum, all the other indications are framed by the retrograde date display. The moonphase is accurate to one day’s deviation in 122 years (a conventional moonphase, driven by a 59-toothed disk, is off by one day every 31.5 months. High accuracy moonphase disks have become more or less de rigueur for haute horlogerie replica watches, whether perpetual calendars or otherwise and given the fact that a perpetual calendar is all about closing the gap between actual astronomical orbital ratios and their mechanical models, it’s a great thing to have.
The degree of saturation of color in the translucent dial works quite well too; it’s light enough that you get a clear look at the perpetual calendar works, but dark enough that critical info really pops, and you get a very nice, subtle-but-definite depth effect as well.
