I love automatic watches and I love Skeleton watches. So it was very easy to choose what I would like to present today: the PerreletFirst Class Double Rotor Skeleton. The name says it all – my first love, when it comes to complication and my first love when it comes to finishes.
The guilloché blue dial is cut out to make visible the double rotor movement – particular for Perrelet.
Packed in a 42.5 mm diameter, 10.7 mm thick stainless steel case with anti-reflective coating on both sapphire crystals (and yes, has a see-through back to enjoy the full view of the skeleton), the calibre P-481 is a marvel. The mainplate and the bridges are circular grained and rhodium plated mounted together with blued screws. The front oscillating weight is beautifully decorated with Côtes de Genève.
P-481 is a double rotor automatic in-house calibre with central hands for hours, minutes and seconds. In terms of performance, P-481 has a ball bearing-mounted oscillating weight coupled with a second inertia weight mounted on the dial offering 42 hours of power reserve and the 4 Hz / 28800 vph beating heart features an anti-shock system with the classic Incabloc® shock absorbers. Moreover, it is a fine adjustment device: heat / cold isochronism and 6 positions – that sounds cool! The oscillating weight is hollowed and adorned with Perrelet decoration.
Here is a video from Perrelet created with the occasion of the 20th Anniversary of the Double Rotor:
