The watchmaker with the French origin which is now completely based in Switzerland, L.Leroy, has unveiled its latest piece from the Osmior Collection called Skeleton Automatic Tourbillon Regulator. This lavish timekeeper is completely made and embellished by hand and it is characteristic for its use of intricate art-deco inspired elements that can be seen on its skeletonized dial. Just like the watch’s face, its movement is also skeletonized and hand-chamfered. There are many other admirable traits of the watch with a regulator-styled outlay of the dial and they involve a flying tourbillion, a double balance spring, a self-lubricating escapement, as well as a chronometer certification for its accuracy. L.Leroy Osmior Skeleton Automatic Tourbillon Regulator timepiece will be made in two restricted issues (in pink and white gold) which will both be limited to just eight pieces and will cost around $221,800.
L.Leroy Osmior Skeleton Automatic Tourbillon Regulator is one of those pieces who will not come unnoticed, which is quite alright since the watch has a lot to show. The very first thing that grabs one’s attention is the presence of art deco ornaments which are visible throughout its lovely skeletonized dial. The new timekeeper has a regulator type of display which means it includes a central hand for the display of minutes, while the hours are represented on an off-centered dial on the lower part of the skeleton face. Both indications come with flame-blued hands. The only other supported indication, the seconds display, is executed via an arrow attached to its flying tourbillion complication which appears to be standing unattached on the very top. All of these are just hints of the present intricacy of the piece which is enabled by its manufacture L.Leroy Caliber L512.
This fully skeletonized and hand-chamfered movement is both beautiful on sight and made with impressive technical traits. It has a peculiar shape of the main plate – it is flat on the upper dial side and rounded on the movement side. Its flying tourbillion is with a variable-inertia balance (the featured frequency is 4 Hz) with four setting screws made of gold. Furthermore, there is a twin balance spring with two coils in opposite directions whose purpose is to level the potential faults of two halves. This system works in the conjunction with the revolutions of its one-minute tourbillion and it all in concert secures much more accurate functioning of the movement that has a chronometric certification as its guarantee of punctuality. Unlike most of the chronometers that we see nowadays and whose accuracy is guaranteed by the stamp issued by COSC, the punctuality of this piece has the certification of the National Observatory in Visancon in France where is the historic birthplace of the brand that today has its facilities completely moved to Switzerland.
It should also be said that the tourbillion has an escapement made of diamond (more precisely, artificial diamond is used for its escape wheel pallet fork) and is made with a StruTech architectonics that requires no lubrication. Apart from improved functioning it provides, these features make the tourbillion exceptionally light with all of its 61 components having the total mass of just 0.8 grams. The self-winding system of Caliber L512 includes a lovely skeletonized 22 K gold rotor which fills the supported power reserve of 52 hours.
As for the case of the new timepiece from the Osmior collection, it is made in 18 K pink or white gold, it is round-shaped and has the diameter of 41 mm. The supported water resistance is 50 meters. For the attachment, the French-Swiss watchmaker picked a genuine hand-sewn black alligator leather strap. There is an option to choose between a pin buckle and a folding clasp, both made in the material which matches the case.
