The "Black Cobra" watch is a distinctive timepiece that incorporates innovative features and design elements. It boasts a unique combination of jumping hours and retrograde minutes, which are set against a striking black background with a bright yellow glow.

What sets this watch apart is the mechanism that powers it. The design of the rack/lever is visible through the display panel on the side of the watch. The lever's honeycomb structure provides both lightness and stiffness, creating a remarkable balance between the two qualities. The mechanism used in the watch is similar to that of slot machines. The toothed segment at the end of the rack moves precisely up and down in a triple cam, each of which drives the frame for exactly 60 minutes. At the end of each 60-minute interval, the rack falls onto the cam, dropping the opposite end of the rack and activating the reversing mechanism that turns the minute cylinder. This process happens in fractions of a second, making it an impressive feat of engineering.

The watch's appearance is also noteworthy. It is a unique piece that is further elevated by an unusual matching bracelet that was a unique upgrade at the time of purchase.
