Why it is interesting

The LM114 deserves attention for combining complications with a long reserve. One pusher reduces the number of controls, while visible mechanics make each operation part of the watch’s character.

Things to consider

The monopusher cycle does not offer the same stop-and-resume freedom as a conventional two-pusher chronograph: after stopping, the next operation is reset. Its 15.1 mm thickness also matters more for fit than the moderate diameter.

The movement in detail

The blue tourbillon cage at six immediately reveals where some of this watch’s complexity sits. Its other protagonist is the large chronograph pusher: start, stop and reset are performed sequentially through one control. Louis Moinet introduced the 1816 Tourbillon Chronograph on April 15, 2026. Detailed October 26 coverage prompts this analysis; it is not a new October premiere.

The LM114 combines a column-wheel monopusher chronograph with a flying tourbillon featuring an off-centre cage. The column wheel coordinates the stopwatch levers; it controls their sequence rather than measuring time itself. The flying construction dispenses with an upper cage bridge and makes the tourbillon more visible from the dial. Concepto participated in movement development, while the official page attributes assembly to Louis Moinet watchmakers in Les Breuleux.

The movement is hand-wound, runs at 4 Hz and comprises 301 components and 36 jewels. Twin barrels provide a stated 96-hour reserve: four days from a full wind. That is useful when alternating this watch with others. The manufacturer gives no separately measured reserve with the chronograph continuously running; treating four days as guaranteed in every operating mode would be wrong.

Reference LM-170.20.60 combines a Grade 5 titanium case and integrated bracelet. Its 40.6 mm diameter looks moderate, but 15.1 mm thickness makes the watch substantial. Water resistance is 50 m and production 12 examples. Fratello quoted $135,000 on October 26 without specifying sales market or tax treatment, so a local quotation should be requested from the brand.
