The Swiss luxury watch and jewellery manufacturer Chopard won the most prestigious award at Wednesday’s annual “Oscars of the watchmaking industry” – the 17th Grand Prix d’Horlogerie de Geneve (GPHG) in Switzerland.

The event – honouring 2017’s best horological creations – saw 72 watches competing for 16 prizes at Geneva’s Théâtre du Léman, with a jury of international experts selecting the winners by secret ballot.

Chopard won the most prestigious award, the “Aiguille d’Or” Grand Prix, for its L.U.C Full Strike Watch.

Chopard also won the Jewellery Watch Prize for its Lotus Blanc Watch.

Zenith claimed the Innovation Prize for its Defy Lab, which the Swiss watchmaker says is “the most precise mechanical watch worldwide ever made”.

The Defy Lab is powered by Zenith’s new oscillator, which is being marketed as “a major innovation in the watch industry since the 1675 invention of the balance and hairspring principle by scientist Christiaan Huygens”.

The Mechanical Exception Watch Prize was won by Vacheron Constantin’s Les Cabinotiers Celestia Astronomical Grand Complication 3600, which has two dials that keep time using 23 complications.

The front dial has 15 complications, including civil time, solar time and a mareoscope indicating tide level and the earth-moon-sun alignment.

On the back dial is the sidereal time, an astronomical time scale, which is based on the Earth’s rotation.
