The Reservoir Sonomaster collection takes its inspiration from measuring instruments widely used in the world of sound or Hi-Fi. The new Reservoir Sonomaster Chronograph Vintage Bi-Retrograde Black and Beige features two retrograde hands that faithfully reproduce the hands of power measurements or VU meters from analog vintage stereo amplifiers. A tribute to the human quest for a ‘pure’ sound, a musical exploration full of audacity and intensity.
