Lederer’s Inverto Titanium brings its double escapement to the front

The Inverto Titanium makes Bernhard Lederer’s movement the face of the watch. Its open construction displays twin barrels, two gear trains and paired constant-force remontoirs beneath a strongly domed sapphire crystal. Skeletonised blue hands preserve a view of the architecture inside the 39mm titanium case.

The hand-wound calibre 9019 supplies 38 hours of reserve and operates at 21,600 vibrations per hour. The remontoirs work on a fifteen-second cycle, while alternating escapement impulses form the heart of Lederer’s concept. December 2025 coverage introduced this smaller titanium interpretation. A seconds indication sits on the reverse, leaving the front focused on the mechanism.
