Notes

No other wristwatch has complications and features comparable to this one. Gérald Genta designed and produced the present wristwatch to commemorate the 25th an-niversary of the Gérald Genta company. It is part of a series of four unique wristwatches, launched in Basel in 1994, which greatly impressed the horological community. Of the four wristwatches in this series, all are different in terms of the complications and of the metals used for the cases (18K yellow or white or pink gold or in platium). Each is there-fore unique. To this first series followed another 6 series of four wristwatches each. Altogether Gérald Genta created 28 unique wristwatches, with the same basic movement but each featuring a different set of complications and different types of cases.
