For 2018, Roger Dubuis again pushes the envelope with several new bold and colorful design iterations in its iconic Excalibur line in conjunction with partners Perfect Fit Pirelli and Raging Mechanics Lamborghini Squadra Corse at SIHH 2018.  Seen here is the new Excalibur Aventador S in a blue and red colorway, featuring RD’s new double sprung caliber with jumping second.
How else to say it except that this is one badass watch.  Check it out below!
Roger Dubuis Excalibur Aventador S Blue
Limited edition of 88 pieces
45mm, multi-layer carbon C-SMC carbon case, Poinçon de Genève, automatic mechanical RD103SQ caliber with double sprung balances with differential (40 hrs)

The watch has a bi-material strap with black rubber base and neptune blue inlay, red stitching, RD pattern on the inside of the strap and a titanium black DLC clasp with adjustable folding buckle and quick release system.
The RD103SQ caliber works at a 2 x 4 hz frequency, giving it a better resistance to gravity effects and therefore a higher precision. That is the reason why the watchmakers at Roger Dubuis have chosen to develop a jumping second in order to emphasize the ultimate precision of this caliber.  The exclusive skeleton double sprung balances in the caliber are directly inspired from the supercar world and has been specifically developped with RD partner Lamborghini Squadra Corse.  Note: images shown below are the same caliber, but with a color-set from a different model
