As for the movement, which uses the 1904 MC as a base, I only wish the rotor was made more interesting. As it is (rhodium plated with black lacquer filled text) it is mundane and no different from lower end Cartier. That being said the finishing is substantially and necessarily better than the same calibre used in entry level watches http://www.waxreplica.co.uk/replica-cartier-roadster-watches-sale-for-uk.html, for example in the bridge bevelling and polishing of the screw heads. This is available in white and rose gold. I received the latter for the review but I prefer the more subdued look of the white gold model.

I think this would do well in the sportier Calibre de Cartier case, especially in titanium. I would not be surprised if that happens in the future. The annual calendar was loaned to me for an upcoming review in the Peak Selections: Timepieces, which will be available at newsstands and bookstores in Singapore from late August 2012.

Alongside the 32 day power reserve ID Two Concept Watch, Replica Tag Heuer Grand Carrera Watches UK | AAA Quality Tag Heuer Grand Carrera For Sale also announced the Astrotourbillon Carbon Crystal. This is the first instance of commercialisation of the technology in the regulation and lubrication free ID One of 2009. The Astrotourbillon Carbon Crystal combines the Astrotourbillon complication with the carbon crystal escapement of the ID One. As some of you might know, the Astrotourbillon is a central carousel tourbillon. That is because a) the balance wheel is not co-axial with the axis of rotation of the carriage and the fourth wheel, making it a carousel; and B) it is a central tourbillon because the tourbillon carriage and fourth wheels of the Astrotourbillon movement are co-axial with the axis of the hour and minute hands and the centre of the movement. For those who know the work of Carole Forestier, Cartier’s head of technical development, the Astrotourbillon in keeping with her past innovations (replica omega seamaster and the concept of the UN Freak). Given the unique characteristics of this tourbillon, it was chosen as the timepiece into which the technology of the ID One is first used on a commercial scale.

The Astrotourbillon Carbon Crystal has the tourbillon bridges, escape wheel and pallet fork in carbon crystal (which is actually artificial diamond). These carbon crystal components are made by Deep Reactive-Ion Etching (DRIE), which produces parts with tolerance of one micron – exceptionally precise by watchmaking standards. So the geometry and precision of the escape wheel and anchor are perfect. Each and every tooth of the escape wheel is shaped as it should be for optimal performance, not always the case with a steel escape wheel (which is why painstaking hand finishing is required). The same goes for the anchor; no ruby pallets held by shellac are needed, eliminating the potential for error in alignment. Just as importantly the parts are extremely hard and smooth; carbon crystal has a Vickers hardness of 10, 000 (sapphire is about 2300). Consequently the contact surfaces of the escape wheel and pallet fork have a friction coefficient of 0. 04 (against 0. 15 for normal steel parts). As a result, the escapement requires no lubrication.
