Jaeger LeCoultre Master Ultra Thin Date
Using the movement is rather straight forward once you get used to it, and people with experience using other T-Touch watches will be right at home. For those who are new to the T-Touch, you need to press the center pusher on the side of the case to active the screen so that you can activate most of the functions. The dive functions are tough to explain thoroughly but make sense. There are two basic dive modes, manual and automatic. In manual mode you tell the watch that you are about to dive by activating the "Dive" function. The watch knows when it touches water and the dive time counter begins. The watch hands turn into the depth gauge using the bezel as a scale. The minute hand will show you your maximum depth while the hour hand indicates your current depth.
The Revelation R0-1 timepiece has a complex movement called the TM01 (which is reportedly in-house made). It is manually wound with 48 hours of power reserve and a tourbillon done a bit like the Cartier Astrotourbillon. Rather than rotating on its own axis, the large escapement moves around like a center fugue under the dial with a counterweight. Revelation calls it their "Tourbillon Menage." The tourbillon structure is so heavy that it takes four linked mainspring barrels to give it 48 hours of power reserve. In most other watches, four mainspring barrels would offer much more power. I believe that the Tourbillon Menage rotates fully each minute. Functions for the watch are just the time.
Even though each of the time dials is partially obstructed, reading the time is very simple on the clean white dial. The blued steel hands shine with quality, but I wish that the minute hands were just a bit longer. Still, the hours hands are of a different shape so legibility is still high. Setting the time is easy and smooth with each of the crowns. Operating the watch is intuitive and something I could do daily.
