Rotonde de Cartier Annual Calendar
At SIHH this week Cartier unveiled the new Rotonde de Cartier Annual Calendar with the all-new manufacture caliber 9908 MC. All indications are set via the crown, and the 45 mm case is available in white gold or pink gold. The annual calendar mechanism is incorporated into the plate of the 1904 MC caliber. The in-house design for the movement includes a semi-instantaneous mechanism for converting the large date into two independent numerals (over a one-hour conversion period), which requires less power and so helps to ensure maximum chronometric stability. In this system, the four-branched star-wheel corresponding to the tens column is turned by the catches located on the large unit disc. This unit disc carries within it a simple mechanism which, thanks to a cam bearing a memory of the months incorporated directly into the lightened rims of the units of the date device, makes it possible to display without any possibility of error the months having 30 or 31 days, once the current month

waterproof 116710LN
I had a question for you guys familiar with the technical aspect of the waterproofing process I had a Sub about 10 years ago that that I had a problem with.I waited to service it about 9 years when I went in to get the service done they did an estimate at the service center and told me that somehow water or water vapor managed to cause the dial to flake is this related to steam or maybe showering with the watch on a frequent basis I also wear the watch at the gym frequently wood either the hot tub or the sauna cause any problems do you think.At the time it was about a $1,500 bill to have the dial replaced all the hands were placed and complete the service I really don't want to have to go through with that again ever by all means please give me your opinions on this

My AD has a TT Sky-Dweller Available
For anyone who might be interested, my northern California AD has a TT Sky-dweller with white dial available and on display in the case. They don't allow phone or internet sales. They require that the buyer pay in person in their store (although you may be able to place a short-term hold on the watch by phone). PM me if you want more info.
