Armin Strom Resonance Dual Time

From the Manufacturer:

The Dual Time Resonance shines a spotlight on Resonance: two independent movements sit side-by-side 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.

The Resonance Clutch Spring is the key to Armin Strom’s mastery of resonance, and the was result of three-years of intensive research and development. Two independent movements display two independent time zones — not simply one movement with two displays.
Armin Strom Co-Founder and technical director Claude Greisler explains, “Developing a perpetual calendar or tourbillon would have been far easier than the years we spent calculating and validating the Resonance Clutch Springs, it was uncharted territory.”
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. Power reserve indicators on each of the hand-guilloche dials and a 24-hour indication at 6 o’clock complete the indications.
“Form follows function” could have been written for the Dual Time Resonance: 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. Gazing through the display back at all four barrels winding simultaneously is as mesmerising as the ballet of the dual regulators on the dial.
