Pierre DeRoche TNT Royal Retro gets power reserve

Pierre DeRoche has upgraded its signature TNT Royal Retro timepiece for 2013 by introducing a power reserve.

The TNT Royal Retro Power Reserve’s movement and the four power-reserve wheels are entirely visible and highly decorated. The watch house describes its latest release as "a fine mechanical blend of strength and deli-cacy".

Like its predecessors, the latest version of the TNT Royal Retro is equipped with a movement that is able to house six retrograde seconds mechanisms with all the retrograde hands driven by gears rather than cams.

A strip-spring in place of the traditional balance-spring system allows the hands to return to the original start positions after passing on the baton to the next retrograde hand.

The TNT Royal Retro Power Reserve will be officially unveiled at BaselWorld in Switzerland next month on the PIerre DeRoche stand.
