A Unique, Quality Piece
A collector and owner of an MIH watch asked Gerber if it might be possible to integrate a moon phase into the caliber of the watch for him. Even the talented Gerber had to pass on this idea, as the layout of the already existent calendar displays takes up the entire surface underneath the dial. But maybe there was a possibility of achieving this if the moon phase display were contemplated separately from the movement. This is how the idea for the micro-moon phase EPR 52 began to take root.
The patent-pending micro moon phase EPR 52 pays homage to Einstein, Podolsky, and Rosen with the initials in its name, while the numeral 52 stands for the 52nd caliber that Paul Gerber has conceived, constructed, developed, and built in his forty-year career. The micro moon phase is designed for a strap thickness of 4 - 4.5 mm, with a width of 20mm.
