Ref. 331

Large Unique Sub Second Display

After extensive research and development, Paul Gerber succeeded in designing and building a new escapement for which he filed an application for a patent.
This novel escapement operates on the principle of equal opposing forces. It features a large stationary wheel, a small impulse wheel and anchor. This new escapement incorporates 3 jewels.

Special

For 10 seconds, the tip of the second hand disappears inside the case. Nevertheless, the seconds can be read at all times

The Paul Gerber‘s in-house Calibre 33 shaped hand wind movement is enshrined in a beautiful, White or Rose 18ct Gold tonneau shaped case. The Calibre 33 bridges are decorated with the «Côte de Genève» at a 33 degree angle. The edges of the bridges are chamfered.

The movement incorporates 18ct Rose Gold gearing and screwed down châtons, which give testimony to the precise methodical design and manufacturing of this unique time piece.
