Roger Dubuis Excalibur Self-Winding with Micro-Rotor and Flying Tourbillon (Ref. EX45-520-20-00/0ER01/B)
Presented this January at SIHH 2011 trade show, the new Roger Dubuis Excalibur Self-Winding with Micro-Rotor and Flying Tourbillon Limited Edition (Ref. EX45-520-20-00/0ER01/B) automatic watch sports a dial layout, which is ideologically similar to that of the gorgeous Piaget Emperador Coussin Tourbillon Ultra-Thin automatic timekeeper also presented earlier this year.
As you can see on the photo below, the new watch comes with two sub-dials that animate its face.
The first one –a flying tourbillon carriage at 7 o’clock– looks quite familiar and even somewhat pestered.
The second one –a skeletonized micro-rotor at 11 o’clock– still looks very fresh and quite inviting. Thankfully, there are still very few watches on the market that show this simple, yet very entertaining complication.
The function comes courtesy of the Calibre RD520 automatic movement that was announced at SIHH 2010, but officially presented only last fall when the company introduced its Roger Dubuis Excalibur Automatic Tourbillon watch in rose gold.
Being quite large (the movement measures 33.84 mm in diameter and is 6.50 mm thick,) the movement requires a formidable casing, so the watch is offered in a large body 45 mm in diameter, which is equipped with the signature indented bezel and a pair of triple-horn lugs that are also characteristic of the Excalibur range.
The rose gold version of the watch that was also limited to only 88 pieces, was offered at a somewhat disturbing price of $160,000, so, I suppose, this model will also be quite expensive.
