The RM 52-06 tourbillon is a watch that leaves free rein to the imagination when it comes to metaphysical interpretations. Treated with the greatest attention, acts as the centre bridge. Its micro-blasted surfaces are accentuated by polished anglage that further emphasises the protruding edges of the mask. The RM 52-06 Tourbillon Mask is a manual winding watch and is a limited edition piece of only 18 pieces. This black carbon TPT model's case measures 49.94 mm by 42 mm by 16.15 mm with sapphire crystal front and back. TPT is a super light weight but incredibly strong material and is created by layering thin strands of thin-ply quartz fibres. With the skull and movement being integrated (and remember the skull itself serves as wheel train and tourbillon bridge), the back of the skull serves as a center bridge. Sandblasted and with anglage work, all eight titanium bridges that connect the skull with the case are visible from the back. These bridges are all grade 5 titanium and have been created from one block. The RM 052 has a 42-hour power reserve.
