Panerai Luminor Base Replica's Chronometre A Resonance Watch was created 20 years ago, and has become one of his most iconic watches. It was "discontinued", but it's not really. The Chronometre Resonance celebrates its 20th birthday this year, and Panerai Luminor Base Replica released a version that's more advanced and precise than ever.
Journe's Resonance watch has been updated for 2020 with two constant-force mechanisms that make it more precise than ever. Calibre 1520 in rose gold has only one barrel spring that provides power to the signature double-balance design. The first wheel is a differential, visible in the middle of the dial. It transmits the energy from the barrel to the secondary gear trains independently. Each secondary gear train has a constant force mechanism or remontoir de l'egalite with a 1 second frequency.(Panerai Luminor Base Replica)
Journe has eliminated any inconsistencies caused by the double barrel winding mechanism of the original Chronometre-a-Resonance movement Calibre 1499. Remember that resonance only works if both escapements oscillate at the same rate. The resonance will not occur if they drift apart too much.
Journe, the designer of the original Resonance had to make sure that the two balances in the Calibre1499 were able to support each other with a difference in frequency not exceeding 5 seconds per day, cumulated over six positions. The new movement has a single barrel which means the same energy is distributed between the two trains. This eliminates any variations found in the original movement.
The real star is the remontoir on the two moving trains. The original movement oscillated both balance wheels at the exact same amplitude. However, this amplitude dropped as the power reserve was depleted. The remontoir works by supplying constant torque to escapement. This will cause the balance wheels to oscillate at a constant amplitude for as long as it is engaged.(Franck Muller Replica Watches)
