Chopard – L.U.C 8HF Power Control
At the BaselWorld 2014 show, Chopard unveiled the new L.U.C 8HF Power Control, an exceptional timepiece housing the L.U.C Caliber 01.09-L equipped with a sophisticated escapement beating at a great frequency of 8Hz or 57,600 vibrations for each hour (ordinary mechanical movements beat at half that frequency or 28,800 vph).
The L.U.C Caliber 01.09-L has successfully breezed through all the rigorous assessments conducted by the Swiss Official Chronometer Testing Institute (COSC), certifying excellent precision and reliability.
A high frequency calibre can offer a significant improvement in the precision timekeeping properties, particularly regarding rate resumption and stability, but there are technological challenges due to possible reliability issues arising out of mechanical resistance and basic wear-and-tear problems. Chopard took the challenge working with silicon for certain escapement components (impulse-pin, lever, escape wheel) and developing a new means of fixing silicon on steel (patent forthcoming).
But the development is not the only element pushing the boundaries of technology in the L.U.C 8HF Power Control. The 42 mm-breadth case comes in high-grade black machined ceramic, a material forced the Chopard specialists to entirely change the case assembly.
This model is water-resistant to 100 meters and presents a DLC-coated titanium case-band, allowing a wide bezel diameter, along with a ceramic crown at 4 o’clock bearing the L.U.C logo.
The case-back, framing a matt black mono bloc along with the lugs, is half closed and features a sapphire crystal situated just over the high-frequency escapement, providing a chance to appreciate it.
On the black sunburst satin-brushed black dial the date is in a pointer-type display somewhere in the range of 5 and 6 o’clock, while the red small seconds hand at 7 o’clock travels exceptionally smoothly thanks to the high-frequency escapement and its 57,600 vibrations each hour.
The approximately 60-hour power save, created by a single barrel, shows up somewhere in the range of 9 and 11 o’clock.
The L.U.C 8HF Power Control is delivered with a highly durable technical fabric equipped with a titanium pin buckle and is issued in a 250-piece limited series.
