The L.U.C 8 HF Power Control – Extra-precise, extra-strong
Faithfully pursuing our determination to push the limits of mechanical horology, we unveil at BASELWORLD the new L.U.C 8HF Power Control model.
The L.U.C 8HF caused a sensation at the time of its launch in 2012. This exceptional timepiece housed L.U.C 01.06-L, the first ever movement with a high-frequency escapement to be chronometer-certified by the COSC. Beating at a frequency of 8 Hz – compared with 4 Hz for ordinary mechanical movements – meaning 57,600 vibrations per hour, this mechanical movement was conceived, developed and perfected by Chopard Technologies in Fleurier.
This exceptional timepiece housing L.U.C Calibre 01.09-L equipped with a high-frequency (8Hz) escapement having successfully undergone the rigorous tests conducted by the Swiss Official Chronometer Testing Institute (COSC), a token of excellent precision and reliability.
57,600 vibrations/hour, COSC certified
After several years of studies and development, the engineers and watchmakers of Chopard Technologies, our horological research division, have succeeded in perfecting a mechanical movement beating at a frequency of 8 Hz, meaning 57,600 vibrations per hour and meeting the most stringent Swiss watchmaking standards. The primary value of high frequency in watchmaking applications lies in a significant improvement in the precision timekeeping properties of a calibre, particularly in terms of rate resumption and stability.
In addition to its COSC-certified precision, this L.U.C 01.09-L movement is distinguished by the highly adaptable nature of its high-frequency escapement. It is indeed compatible with almost all existing L.U.C movements developed by the Chopard Manufacture, although it is currently reserved for special and exclusive versions. In terms of materials, the engineers at Chopard Technologies decided to work with silicon for certain escapement components (impulse-pin, lever, escape wheel) and developed a new means of fixing silicon on steel (patent pending).
L.U.C 8HF Power Control: new materials for a technological challenge
The new L.U.C 8HF Power Control takes on even greater character and technical sophistication thanks to a new design. It now comes in high-grade black machined ceramic. The various production, assembly and design constraints relating to this material forced the Chopard engineers to entirely revise the case assembly.
This model is water-resistant to 100 metres and presents a DLC-coated titanium case-band, allowing a broad bezel diameter, along with a ceramic crown at 4 o’clock bearing the L.U.C logo. This resolutely avant-garde model features monobloc matt black ceramic lugs and case-back, as well as a screw-down crown guard with the same finish. A sapphire crystal built into the half-closed case-back is positioned just above the high-frequency escapement, providing a chance to appreciate its finer details.
The L.U.C 8HF Power Control is teamed with a highly durable fire-retardant technical fabric equipped with a titanium pin buckle and is issued in a 250-piece limited series.
