[Comment] Although the 43 mm diameter case does not seem to be outstanding today, IWC watches can always make people truly experience great harmony. This is firstly attributed to the tradition of IWC’s use of large pocket watch movements, as well as the great tension shown in the design of IWC watches. Especially for Portuguese series watches, the extremely narrow bezel further enhances the visual effect of the dial. This year is the anniversary of the launch of the Portuguese series of watches. IWC has added several new models on the basis of the original models. It can be said that the Portuguese series is ready to fight in the new year.

Richard Miller Rm52-01 Nano Ceramic Skull Tourbillon Watch

The RM 52-01 skull tourbillon watch is another new work by Richard Miller, which also confirms the brand’s creative freedom. Following in the footsteps of RM 052, it is the second collection of skull works launched in 2012 and features the Richard Mille brand to symbolize the skull pattern: an anti-traditional approach, focusing on innovation and development, each of which is new The watch embodies the appeal of the watchmaking revolution.

 The RM 52-01 skull manual winding tourbillon movement has a PVD-treated grade 5 titanium base plate. PVD-treated titanium provides excellent rigidity and a completely flat surface, and a series of tests have been performed before. Richard Miller’s application in the new watch is the use of materials.

 Research on RM 055 and RM 011 silicon nitride bezels, Jura watchmaker ceramics develops advanced expertise, excellent skills in designing complex shapes, and most importantly, has managed to reduce the production of ceramics with unmatched quality raw materials Porosity.

 TZP was selected as the bezel and bottom cover of the RM 52-01. This low density material (6 g.cm3) is highly scratch resistant and has a low thermal conductivity. TZP is made of 95% yttrium-stabilized zirconia, has obvious grain, and provides a perfect period. Bezel and bottom cover, so the corners can be microblasted and hand-polished.

 Richard Miller decided to prove their ability to protect the tourbillon movement, located in the center against the use of carbon nanotubes. The case of black polymer-bonded carbon nanotubes in the middle helps reduce the weight of the watch.

 The case of these three parts is very light and dark in color. An average of 20 spline screws are assembled using grade 5 titanium alloy. The DLC-treated torque-limiting crown provides the finishing touch. RM 52-01 released a limited edition 30 nanometer ceramic clock with an 18K redgold skull.
