Baume & Mercier Unveils New Technology in Clifton Manual 1830 WatchsharetweetshareFollowing through to such horological milestones as 2014's flying tourbillon model, and last year's pocketwatch with five-minute repeater, Baume & Mercier adds another notable timepiece for the vintage-inspired Clifton collection. The Clifton Manual 1830 appears simple on the lateral side, but inside is an all-new proprietary movement, the first one to be pre-loaded with a privileged, accuracy-improving system called TwinSpir.Baume & Mercier Clifton Manual 1830 - frontInside the watch's 42-mm polished and satin-finished rose-gold case could be the new manual-winding Caliber BM12-1975M, created by Baume & Mercier in collaboration with the movement specialists at Manufacture Horlogerie Valfleurier. panerai copies The movement, containing 18 jewels along with a 28,800 vph frequency and boasts a power reserve of 90 hours, comes with the exclusive TwinSpir technology, which includes a variety of technical innovations developed by the Research & Innovation department at Richemont, parent company of Baume & Mercier and a volume of other luxury watch brands.The TwinSpir technology is centered around a newly developed hairspring with a composite structure combining two layers of silicon, alternatively oriented and bound with an extra layer of silicon dioxide, that also behaves as a thermo-compensating element. Together with the movement's other noteworthy technical element a newly designed, inertia-type balance wheelthe technology has several benefits, according to Baume & Mercier. Included in this are improving the precision on the movement in various positions and also over time; limiting the movement's sensitivity to surrounding magnetism; and ensuring a larger ability to resist small shocks and repeated vibrations.Baume & Mercier Clifton Manual 1830 - backTo get into a bit more technical detail rolex cosmograph daytona , the monocrystalline silicon found in hairsprings is a non-magnetic, light, corrosion-resistant material that exhibits different elastic and thermo-elastic properties for different crystalline orientations a variation of response referred to as the material's "elastic anisotropy." Like a watch's hairspring expands and contracts during its oscillations, the elastic anisotropy will customize the evenness of such oscillations and, consequently, the watch's chronometric performance. The TwinSpir system overcomes these limitations through its combination of two layers of silicon, with different crystalline orientations, in order that the variations are balanced, thus making the oscillations more even as well as the timekeeping, therefore, more precise. Moreover, an additional outer layer of silicon dioxide works in collaboration with the inner, thermo-compensating layer of the same substance to guarantee a gradual performance with the hairspring across an array of temperatures watches .Baume & Mercier Clifton Manual 1830 - two-shotFinally, Caliber BM12-1975M's newly designed balance wheel is an inertia adjustment type, instead of the classical type which uses an index-pin assembly. With all the latter kind of assembly, the balance's rate might be adjusted only through correcting the active whole hairspring. Inertia-adjustment types, in comparison, offer the key good thing about a much more vibrations-resistant rate setting, as being the inertia-adjusting weights which ensure that the precise adjustment from the watch rate are securely held about the balance wheel between its arms and dedicated supports.The Baume & Mercier Clifton Manual 1830 shows a classy, understated face, with its opaline silvered dial enhanced with 18k rose gold hour numerals and indices and gilt hour and minute hands. Conversely, the movement's haute horlogerie decorations including côtes de Geneve around the bridges , circular graining within the mainplate, blued screws, and engraved text are saved to display by way of a screw-down sapphire caseback. The black alligator strap is secured with a rose-gold pin buckle. Baume & Mercier says that this watch are going to be manufactured in limited quantities; priced at 12,000 Swiss francs (approximately $12,045), it truly is available at retail by April 2017.sharetweetshare replica antique breitling watches
