Armin Strom this week releases a rose gold version of its Gravity Equal Force, an innovative time-only design with an unusual constant-force mechanism.
The watch, which Armin Strom debuted in steel last year, features an in-house movement that takes a cue from high-precision pocket watches of yore. The watch’s ASB19 automatic movement features a motor barrel (where the mainspring resides) that stays locked after the watch is wound, creating a more precise arbor to rotate and drive the gears that move the watch’s hands.
Effectively, the watchmakers at this independent Swiss atelier added a stop-work de-clutch mechanism to the automatic watch, driving consistent power to the balance.
As Armin Strom explains “it is clear that it is a demonstrably better system as it is more precise and stable during operation of the movement. Armin Strom’s watchmakers built on this idea to create an entirely new watch.”
The Gravity Force debuted with a steel case last year as an update to the Armin Strom Resonance Clutch Spring that first demonstrated the brand’s retro-futuristic approach to delivering constant force within its automatic movement.
This newest rose gold-cased version brings along a bit of luxury to what remains a technically focused watch.
When it debuted, the watch’s 41mm case was a new size for the brand. That size remains on this new model, as do the dominant three bridges that echo the vintage pocket watch inspiration behind the movement’s design. Here the bridges are gold, creating a luxurious contrast with the black dial.
The Armin Strom Gravity Equal Force in rose gold is priced at $26,600.
