When H. Moser & Cie. launched the Pioneer collection in 2015, it represented the brand’s vision of an everyday watch. With its sizable 42.8mm case and 12 ATM water resistance, it was built to be a dependable companion, while the stripped-back dials reinforced Moser’s signature minimalist aesthetic. Over the years, the collection evolved to incorporate sophisticated complications, including the Flying Hours.

This complication in particular is H. Moser & Cie.’s modern take on the wandering hours concept. Unlike traditional watches where hour hands sweep around a fixed dial, the Flying Hours system uses rotating discs: three small hour discs orbit a central minutes disc, where each disc rotates on its own axis, aligning the correct hour in a window on the dial, while the central disc tracks the minutes over a 120° arc.

H. Moser & Cie Pioneer Flying Hours in 5N red gold with features an aventurine dial which evokes a deep and mysterious constellated sky. It is limited to 100 pieces

The steel version takes on a subtle industrial aesthetic with a clean, white fumé dial

Now seven years after the first Flying Hours model, Moser updates the model with two new references: a 5N red gold case with black DLC titanium inserts, and the other in steel. Both deliver distinct personalities; the red gold model frames a starry aventurine dial, making the central minute wheel almost invisible in certain angles, while the hours jump instantly into view. Unlike the first generation of Flying Hours, where the numerals slowly faded in and out, this new version features an instantaneous jump, making the hours clearer and far easier to read at a glance.

The steel version with a white fumé dial offers a cleaner, more legible contrast to its aventurine counterpart, the former immediately less dramatic but definitely more legible. The HMC 240 automatic caliber fuels this kinetic ballet. Bi-directional winding provides a minimum three-day power reserve, with oscillating weights crafted from solid red gold or tungsten depending on the model.
