Ulysse Nardin is moving ahead with several in-house calibres and many of their iconic timepieces have been reintroduced with new in-house movements.
One such icon is the UN Perpetual Manufacture which was covered in my other blog and this one - the Dual Time Manufacture seen here taken at the restaurant where the luncheon was being hosted.
The first Dual Time GMT were called the "plus" and "minus" as the push buttons at the eight and ten o'clock positions were used to advance or reverse the hour hands. The original Dual Time GMT used a Soprod movement and was one of the few watches that you could adjust without taking it off.
Notice the push buttons on the left side of the case? That feature still stays in the all new Dual Time Manufacture. Fitted inside is the automatic UN-334 in-house designed movement with a silicium escapement.
The small window at the 9 o'clock displays the home time in a 24 hours display. The large date at 2 o'clock can be adjusted forward and backwards when the push buttons are depressed. This dual time is perhaps one of the easiest to operate - save the Reverso. The winning feature here is that the Dual Time GMT can be adjusted forward and backwards whereas the Reverso adjusts one way - forward.
The timepiece is 46mm in diameter and limited to 20 pieces. Case is white gold. Housed in the case is the manual winding mechanism that has an ingenious winding system that winds the barrel system providing energy to the complication for chiming and powering the watch.
Pardon the poor quality of the photos - does not do justice to the excellent timepieces I handled. Thanks to UN and the Hour Glass for hosting the lunch at MBS.
