Recently some forum members have managed to acquire Nina bezels direct from Universal Geneve (the beast is stirring, apparently) after making contact via their homepage. If the bezels are still available, however, be warned that they come at very high premium and have a missing grave accent over the 'E' in 'TACHYMETRE' AND you will have to trade in your existing one......good luck!
