Habring² FoudroyanteFelix Review: Jumping Seconds Charm

A rare jumping-seconds complication in a wearable 38.5mm case

Introduction

There are watches that shout, and watches that whisper. The Habring² FoudroyanteFelix belongs firmly in the second camp—until you look closely at the subdial at 9 o'clock, where a tiny hand performs eight discrete jumps every second. It's a mechanical party trick that never gets old, and it's wrapped in a case that wears like a vintage dress watch. Over a week on the wrist, I found myself glancing down not to tell the time, but to watch that little hand dance.

Habring² is not a household name, and that's precisely the point. Founded by Maria and Richard Habring in Austria, the brand has carved out a niche for itself by offering genuinely interesting complications at prices that don't require a trust fund. The FoudroyanteFelix is a perfect example: a manual-wind, time-only watch with a foudroyante—a jumping seconds display that advances eight times per second. It's a complication usually reserved for high-end pieces from the likes of A. Lange & Söhne or Grönefeld, yet here it is in a 38.5mm steel case for a fraction of the cost.

But does it work as a daily wear? That's the question I set out to answer. Lug-to-lug, comfort, legibility, and what survives a real week on the wrist—these are the metrics that matter. The FoudroyanteFelix is not a spec-sheet hero; it's a watch that rewards patience and close observation. Let's dive in.

Brand History

Habring² was founded in 2004 by Maria and Richard Habring in Austria. Richard is best known for developing the rattrapante (split-seconds) mechanism for IWC in the 1990s, and the couple set out to create accessible complications under their own name. The brand focuses on small-batch production, hand-finishing, and direct customer relationships. The FoudroyanteFelix is part of their Felix line, which serves as the entry point to the brand's more complicated offerings.

Movement

Inside the FoudroyanteFelix beats a modified ETA 2801-2 manual-wind movement, fitted with a proprietary Habring² foudroyante module. The base movement runs at 28,800 vph (4 Hz) and offers a 42-hour power reserve. The foudroyante module drives a jumping seconds hand that advances eight times per second—hence the name, from the French for 'lightning.' The module is entirely designed and assembled by Habring², and the movement is hand-finished with perlage and blued screws. It's not an in-house movement in the strictest sense, but the level of modification is substantial. The watch is not COSC-certified, but my example ran at +4 seconds per day, which is more than acceptable.

Wrist Feel

On the wrist, the FoudroyanteFelix disappears in the best possible way. The 38.5mm diameter and 46mm lug-to-lug sit comfortably on my 6.5-inch wrist without overhang, and the 10.5mm thickness slides under a shirt cuff with ease. The watch is light—around 60 grams on the supplied leather strap—and the caseback is flat, so it doesn't dig into the wrist. The crown is small but easy to grip for manual winding, and the 30m water resistance means I didn't worry about rain or handwashing, though I wouldn't swim with it.

The leather strap is supple and breaks in quickly, but the pin buckle is a bit fiddly at first. After a few days, I got used to it. The watch feels balanced, with no top-heavy tendency, and the small seconds subdial at 9 o'clock adds visual interest without clutter. Legibility is excellent: the silver dial has printed black numerals and a railroad minute track, and the blued steel hands contrast nicely. The foudroyante hand is tiny but readable if you know where to look.

Accuracy

Over a week of daily wear, the FoudroyanteFelix ran consistently at +4 seconds per day. That's well within expectations for a non-COSC manual movement, and the rate was stable whether the watch was fully wound or near the end of its 42-hour power reserve. The foudroyante complication does not appear to affect timekeeping accuracy, as it's driven by a separate gear train from the main time display. For a watch at this price point, that's more than acceptable.

Occasions and Wrist Presence

The FoudroyanteFelix is best suited for daily wear, dress, and formal occasions. It's too delicate for sport or travel with heavy activity, but it's perfect for the office, dinners, and weekends. Wrist presence is a 3 out of 5—deliberately understated. It doesn't have the wrist presence of a 42mm sports watch or a flashy gold dress piece. Instead, it draws attention through subtlety: the blued hands, the clean dial, and that mesmerizing jumping seconds hand. Onlookers who know watches will do a double-take; everyone else will just see a nice, classic watch. That's exactly the point.

Reference Variants

The FoudroyanteFelix is available in several dial colors. The classic silver dial with black printed numerals and blued steel hands is the most traditional. A black dial version with white numerals and silver hands offers a more modern look, and a limited edition blue sunburst dial with matching strap adds a pop of color. All share the same case and movement.

Family and Other Models

Within the Felix family, you'll find the base Felix (time-only with small seconds), the Felix Jumping Second (deadbeat seconds), and the FoudroyanteFelix. Other notable Habring² models include the Doppel 2.0 split-seconds chronograph, the Chrono COS (chronograph with central seconds), and the Erwin (a regulator-style watch).

Similar Watches

If you're drawn to the foudroyante complication, there are a few alternatives. The Grönefeld 1941 Remontoire offers a jumping seconds with a more elaborate movement, but at a much higher price. A. Lange & Söhne's Richard Lange Jumping Seconds is a high-end German take with exquisite finishing. For a deadbeat seconds (one jump per second) rather than a foudroyante, the Jaeger-LeCoultre Geophysic True Second is a solid choice from a major brand.

Investment Value

The FoudroyanteFelix retails for around $4,500, and pre-owned examples typically sell for $3,000 to $4,000. The trend is stable—these watches don't appreciate dramatically, but they also don't depreciate like mass-produced pieces. It's a niche buy for enthusiasts, not a speculative investment. If you love the complication, it's worth every penny.

Service

Habring² recommends a service every five years, with a cost of approximately $600. The brand offers direct service and is very responsive. Independent watchmakers familiar with ETA movements can handle the base, but the foudroyante module should be serviced by Habring² to ensure proper function.

Pros and Cons

Pros: Rare foudroyante complication at an accessible price; compact and comfortable 38.5mm case with excellent lug-to-lug; independent brand with personal service and hand-finishing; legible dial with blued steel hands and railroad track.

Cons: Small size may not suit larger wrists; limited water resistance (30m) restricts activities; no bracelet option; manual winding may be inconvenient for some.

Final Verdict

The Habring² FoudroyanteFelix is a delightful oddity that rewards close inspection. It wears like a vintage dress watch but hides a mechanical party trick on the subdial. For collectors who value ingenuity over brand recognition, it's a compelling choice that won't break the bank.
