<strong>RM</strong> <strong>008</strong>-V2 FELIPE MASSA CLOSURE OF THE BARREL COVER USING EXCENTRIC SCREWS This developm<strong>en</strong>t is again part of the int<strong>en</strong>tion to make servicing easy, logical, and of a very high mechanical standard. TORQUE LIMITING CROWN This added security system prev<strong>en</strong>ts accid<strong>en</strong>tal overwinding of the watch, the result of which can cause damage such as breaking the winding stem or putting too much pressure on the barrel spring. SPLINE SCREWS IN GRADE 5 TITANIUM FOR THE BRIDGES AND CASE This permits better control of the torque applied to the screws during assembly. These screws are therefore unaffected by physical manipulation during assembly or disassembly and age well. TOOTH SYSTEM OF BARREL AND THIRD-WHEEL PINION WITH CENTRAL INVOLUTE PROFILE The wheel with a c<strong>en</strong>tral developing profile and a pressure angle of 20° promotes rolling movem<strong>en</strong>t more effectively, comp<strong>en</strong>sates differ<strong>en</strong>ces betwe<strong>en</strong> c<strong>en</strong>ters, <strong>en</strong>sures excell<strong>en</strong>t torque transmission and a distinct improvem<strong>en</strong>t in performance.
