Launched with the first Dual Time Resonance model in titanium, that defined its basic design, the Masterpiece collection has now been extended to include versions in white gold and 18 carat rose gold, each in a limited edition of 8 pieces.
The Dual Time Resonance is characterized by the two independent movements sitting side-by-side and housed in a distinctive oval case. Their regulators wedded by Armin Strom’s patented Resonance Clutch Spring performing a continually horological two-step between the dual eye-catching counter-oscillating balances. Independent movements enable the Dual Time Resonance to indicate GMT, or a second time zone, as well as a function used as a timer or countdown. Each of the hand-guilloche dials feature a power reserve indicator and a 24-hour indication at 6 o’clock.
“Form follows function” could have been written for this watch. The two movements side by side (rather than stacked vertically) naturally led to the oval-shaped case, while the increased space afforded by the movements in this configuration allowed for two barrels per movement and a longer power reserve. The four barrels winding simultaneously are to be seen through the display back and the ballet of the dual regulators is visible on the dial.
While it has been long known that resonance in watch and clock movements with synchronized coupled oscillators improves accuracy by averaging slight differences in the precision of each movement and in wristwatches minimises adverse effects of shocks on precision. Less known is that resonance also conserves energy: vibrational energy that is normally be lost through the supports of the regulator is conserved in the system. Armin Strom’s laboratory testing has revealed gains in precision of 15-20% for two COSC chronometer-level regulated movements placed in resonance.
