Every Greubel Forsey 2025 Release Explained

As one of the most influential names in six-figure independent watchmaking, Greubel Forsey has set expectations high for themselves. Inclined balance wheels, unusual tourbillons, and phenomenal finishing have been signatures of the brand ever since their 2004 debut. But their 2025 novelties should impress even the most jaded enthusiasts. Three dramatic new Convexe models, an ultra-rare and aptly-named Hand Made 2, and the final edition of the beloved Balancier Contemporain make up the five Greubel Forsey 2025 releases. Let’s get into it.

2025 Greubel Forsey QP Balancier

At Geneva Watch Days 2025, Greubel Forsey released the Quantième Perpétuel Balancier, a new perpetual calendar with a good reason for its CHF 490,000 price tag. “Simplified” is probably not the first word that comes to mind when you look at it, but it really is a simplified version of the mind-melting Quantième Perpétuel à Équation first seen in 2014. The equation of time, solstice/equinox indicators, and 24-second inclined tourbillon have all been dropped for the new 2025 QP Balancier. Instead, we get a large, free-sprung, 30° inclined balance wheel on the left side of the dial. 22 examples will be made.

Inside we still get Greubel Forsey’s “mechanical computer” movement, considered one of Greubel Forsey’s ten major inventions. It’s conceptually similar to MB&F‘s “mechanical processor,” though the technical execution differs. Both are innovative, stack-based mechanisms that replace the traditional lever/cam system, enabling a more robust and user-friendly perpetual calendar that can be set easily and worry-free forwards or backwards.

As complex as it is, it’s a deceptively legible watch. While the off-center 24-hour indicator, numerical small seconds, and power reserve displays provide a distinctively asymmetrical aesthetic, the impressive big date display is situated in the middle of the day and month windows for intuitive reading.

The perpetual calendar treats every fourth year like a leap year, but there are “exception years” (like 2100) that are not leap years. So, you or your heirs will need to send this bad boy back to Greubel Forsey in the year 2100, at which point they’ll also swap the little “20” plate with a “21” plate.

Looking beyond the technical specs, Greubel Forsey uses a variety of finishes and techniques harmoniously. Deep chamfers, mirror-polished screws, hand-applied straight-grain textures and sandblasted surfaces are all present. There’s not much to dislike other than the price, and–if you don’t have a large wrist–its 45.1mm diameter and 14.75mm thickness. The nicely contoured lugs should make it wearable on most wrists, but regardless, let’s talk about a smaller 2025 Greubel Forsey release.

2025 Greubel Forsey Nano Foudroyante

With a case measuring 37.9mm wide, the Greubel Forsey Nano Foudroyante is the brand’s smallest model ever. The first version debuted in 2024 and it’s also one of Greubel Forsey’s ten major inventions, but as part of their “Experimental Watch Technology” program, only 11 were made. There’s a new appealing colorway with blue accents for 2025, and this time, a whopping 22 will be made. If you want one, expect to pay just over $500,000.

The “nano” refers to nanomechanics: the control and management of energy at the nanojoule scale within a mechanical movement, not the literal miniaturization of components. A series of ultra-lightweight low-inertia gears allows Greubel Forsey to efficiently power the foudroyante complication, which means a seconds hand that rotates fully once per second. This complication is sometimes called the “little devil” because it consumes so much energy, but Greubel Forsey claims they have reduced energy consumption by a factor of 1,875x, requiring only 16 nanojoules per “jump” and thus 96 nanojoules per second.

Although a constant-running Foudroyante mechanism is impressive in itself, Greubel Forsey has taken it to the next level by putting the fuodroyante hand on a flying tourbillon. And to top it all off, it’s a monopusher flyback chronograph. Interestingly, this is GF’s only chronograph model.

Habring² is the only other watch brand that offers a continuously-running foudroyante. Both brands deploy the idea that the “ticking” of the escapement, already present and dividing the second, can be used to drive a fractions-of-a-second display without a separate chronograph module or additional gear trains. This means the complication doesn’t require interrupting, duplicating, or dramatically amplifying energy flow—resulting in inherent efficiency compared to classical chronograph foudroyantes. Most well-known foudroyante complications (from the likes of Hublot, Girard-Perregaux, and La Joux-Perret) are chronograph-activated only in order to conserve energy.

Balancier Contemporain Final Edition

When the Greubel Forsey Balancier Contemporain first appeared in 2019 with a 39.6mm case, it marked the brand’s first move into more “wearable” case size territory, while maintaining the aesthetic they’re known for. Although the Balancier Contemporain looks quite complex, a power reserve display is its only complication beyond hours, minutes and small seconds. This sunburst blue version looks like a worthy swan song for the model, although a six-year run seems rather short for such a significant watch.

The 2025 iteration of the Greubel Forsey Balancier Contemporain is a 33-piece final edition in stainless steel, a material rarely used by the brand. Like other Balancier Contemporain models–which all have solid gold cases–it sports a solid gold dial, and the dramatic 12.6mm in-house balance wheel as its centerpiece.

The gorgeous manually-wound movement provides a 72-hour power reserve, and the case is rated at 30 meters water resistance. But those specs aren’t the reason you spend 220,000 Swiss francs on a Greubel Forsey like this. You can get lost in the multi-tiered dial. The finishing is obsessive, layering blue accents and architectural gold with hand-finished nickel silver bridges,

GMT Balancier Convexe

The 2025 Greubel Forsey GMT Balancier Convexe is notable as the brand’s first GMT without any tourbillon. Predecessors like the GMT, GMT Earth, GMT Sport, and GMT Quadruple Tourbillon all were built around either single or multiple tourbillon architecture. Instead, this reference introduces the brand’s 30° inclined balance wheel system, housed in a sculptural titanium Convexe case (42.9mm caseband, 44.9mm bezel), and integrating a central rotating globe, universal time, day/night indication, and a GMT pusher.

The spectacular three-dimensional dial could be described as “ampitheater-like,” and it certainly doesn’t seem like it’s missing anything without a tourbillon.

While Greubel Forsey has been one of the leading innovators in tourbillon technology this century, they now seem to be making a statement that they don’t need to put tourbillons on everything to make them impressive. In fact the most impressive 2025 Greubel Forsey release of all is another model that sheds the tourbillon of its predecessor. Let’s talk about that now.

Hand Made 2

The Hand Made 2 is Greubel Forsey’s ultimate demonstration of watchmaking purism: a time-only, manually wound piece with nearly every component—gear, pinion, spring, balance, wheel, and even the hairspring—shaped and finished by hand, resulting in more than 5,000 hours of labor per watch. The 40.9mm white gold case is classic, and certainly understated compared to the brand’s more sculptural models.

There’s no tourbillon here (unlike the Hand Made 1 or “Handwerkskunst”); instead, a free-sprung balance and superlative hand-shaped bridge architecture anchor the movement.

The dial layout is ultra-traditional: hours, minutes, small seconds, and a sector power reserve, but each element is elevated by black-polished steel, hand-engraving, and mirror bevels with no CNC in sight. As with the original, only 2-3 will be made per year. That’s why it costs about $778,000–roughly the cost of a new GMT Balancier Convexe and Balancier Contemporain Final Edition put together.

The handcrafted conical power-reserve jewel is a good example of the ridiculous level of detail here. Greubel Forsey is one of the most expensive watch brands in the world for a good reason.

All five of the 2025 Greubel Forsey releases have manual-wind movements with three-day power reserves. Let’s get into all the specs.

These 2025 releases continue to give us what we expect from Greubel Forsey–which is a lot. And while we’ve seen a flurry of expensive tourbillon watches over the past decade or so, perhaps GF will lead us into the next chapter beyond the every-six-figure-watch-needs-a-tourbillon era. I can’t think of anyone more worthy to do it.
