Notes

Dial, case and movement signed. DIAM. 44 mm. THICKNESS 12 mm. Upon the launch of the SPIRIT OF CHALLENGE line, the watchmakers were given the challenge to develop in-house a perpetual calendar movement and were given 2 challenges. The first was that at least 3 displays on the complication were retrograde and the second was that it has to be developed and working within 12 months. The challenge was fulfilled and this is one of the three prototypes made that launched the model. Its retail price in 2003 was CHF 62'000.
