Konstantin Chaykin’s ThinKing Mystery makes extreme thinness part of a face

The ThinKing Mystery uses separated hour and minute indications to avoid stacking hands over one another. Transparent sapphire discs give its face a mysterious quality, while the ultra-flat mechanism integrates closely with the case. Chaykin states a total watch thickness of just 1.65mm.

An April 2026 interview describes the twelve-piece series, following the earlier ThinKing prototypes. The hand-wound mechanism has a stated 38-hour reserve and is operated with separate winding and setting tools. Chaykin also explains the need to protect the thin structure from impacts and bending. This is a profile of that specialised engineering project, rather than an assertion of present-day record status.
