Cal. C99002 is based on the Valjoux 7750 design but features a central date pointer. It is produced by Concepto Watch Factory of La Chaux-de-Fonds, which also produces Cal. C99001. It was designed to be 100% compatible with that famous automatic chronograph, exactly the same size and design. One major differentiator was the use of Concepto’s in-house assortiment, including the balance, spring, and anchor.
The most obvious difference between Cal. C99002 and Cal. C99001 is the central date pointer. But Cal. C99002 also adds a month window and relocates the day window alongside it in the 30 minute subdial at 12:00 on the dial.
