The L.U.C 8HF model from Chopard houses the first high-frequency (8Hz) escapement to have successfully undergone the rigorous tests conducted by the Swiss Official Chronometer Testing Institute (COSC), a token of excellent precision and reliability.
After several years of studies and development, Chopard has 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 ensuring greater reliability, high frequency – which naturally requires more energy – is in this instance associated with a remarkable 60-hour power reserve generated by a single barrel.
The 42 mm-diameter case of the L.U.C 8HF model is made of titanium. It is water-resistant to 30 metres and distinguished by its crown at 4 o’clock, also in titanium and bearing the L.U.C logo.
The date appears in a pointer-type display at 5.30, while the red small seconds hand at 6 o’clock moves far more smoothly than on ordinary watches thanks to the high-frequency escapement and its 57,600 vibrations per hour.
The resolutely avant-garde case features titanium monobloc lugs and caseback with a matte finish. A magnifying glass 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 model is teamed with a hand-sewn matte black alligator leather strap with a cognac-coloured alligator lining, fitted with a titanium pin buckle. It is issued in a first 100-piece limited series equipped with the high-frequency experimental L.U.C 01-06-L movement.
