Ulysse Nardin Perpetual Calendar GMT, Platinum.
Which I had the pleasure to own, some 20 years ago, but which was aesthetically too close to the Sonata.
Gone, but not forgotten.
In platinum, it had the weight of a dead donkey. Not very comfortable, but a lot of character. Without forgetting that this is one of the very rare perpetual calendar you can set front and backward.
Typically Ulysse Nardin.
Best,
Nicolas
