THE SILHOUETTE
EXTERNAL KINEMATIC
INTERFACE
Given the constraints of an ultra-thin watch, Konstantin Chaykin chose to eliminate the traditional crown. Winding and time-setting are performed using two separate tools, each equipped with a built-in safety mechanism that prevents over-tensioning of the mainspring.
The watch can be placed in a miniature winding box, where winding and time-setting are performed via two wheels integrated into the case. Alternatively, a slim key can be used by inserting it into the designated slot on the caseback.

ALLOCATION REQUEST
Allocation approval is determined following a closed review process.
Priority status may be granted to existing collectors of the manufacture, long-term partners, and candidates with a substantiated interest in the project.
DOUBLE
BALANCE
The primary balance is responsible for frequency and isochronism, while the intermediate balance functions as a carrier for the impulse jewel and interacts with the escapement fork.
The two are coupled via gearing on their rims.

BARREL
The barrel arbor is designed as an overrunning clutch with tungsten carbide balls.

INDICATION
In the latest version, a lateral drive rotates solid sapphire discs, inherently eliminating axial runout. Additional stability is ensured by three rollers positioned around each indicator: they guide its motion, effectively reducing radial runout to near zero and lowering energy losses from the mainspring barrel.
