Introduction

There are watches… and then there are Greubel Forseys. Pieces that don’t simply tell the time, but articulate an entire philosophy of watchmaking—one grounded in uncompromising finishing, architectural movement design and extreme mechanical pursuit.

The Double Balancier Convexe Titanium sits firmly in that category. It is one of those pieces that, the moment you place it on the wrist, immediately shifts your perception. Everything feels different—the lightness, the depth, the visual complexity. You don’t “wear” it so much as you experience it.

This particular Greubel Forsey is an exploration of precision through twin inclined balance wheels, wrapped in the brand’s more contemporary Convexe aesthetic. And personally? It might be one of the most wearable Greubel Forseys ever produced—sculptural, futuristic, and unexpectedly comfortable on the wrist.

First Impressions (Aesthetics and Dial)

Your first look at the watch is a sensory overload—in a good way.

The dial isn’t a dial in the traditional sense; it’s a three-dimensional mechanical landscape. The twin balance wheels, each inclined at 30 degrees, sit on opposite sides of the open stage, connected by a differential that blends their rates into a single, ultra-precise timekeeping signal.

The colourway, depending on the variant, mixes dark frosted titanium plates, angled bridges, matte textures and mirror-polished bevels. It’s not loud. It’s technical. Refined. Almost architectural.

Then your eye shifts to the small seconds register, the power reserve at two o’clock, and the hand-finished components tucked into every corner of the movement. Everything is visible. Nothing is hidden. It’s Greubel Forsey essentially saying:

“If we’re going to make the best-finished parts in the world, you’re going to see every one of them.”

It’s a dial you could stare at for an hour—and still not catch every detail.

Case and Dimensions

Here’s where things get interesting.

The Convexe case shape is a modern departure from the brand’s earlier aesthetic: smoother, more ergonomic, elegant in a futuristic way.

Dimensions:

• Diameter: 42.5 mm
• Thickness: 14.35 mm
• Material: Grade 5 TitaniumNow, on paper 42.5 mm sounds big, but the curved profile of the case—and the lightweight titanium—dramatically change the wrist presence:
• It hugs the wrist.
• It feels slimmer than the numbers suggest.
• It sits flat, stable, and comfortable, even on medium wrists.

The bezel and case flanks flow like a continuous sculpture, with sharp polished lines separating brushed surfaces. It’s visually dynamic from every angle.

This is Greubel Forsey done in a way that’s wearable daily—not just a safe-drawer masterpiece.

Movement

This is where the watch becomes mind-bending.

The Double Balancier Mechanism

Two independent balance wheels, each inclined at 30 degrees, oscillate separately. Their rate differences are resolved via a spherical differential, averaging their behaviour to dramatically improve chronometric stability.

This level of mechanical pursuit is rare. Very rare.

Key movement highlights:

• Manual-winding calibre with 72-hour power reserve
• 178 components dedicated to the regulating organs alone
• Spherical differential
• Multi-level bridges
• Hand-polished bevels everywhere (including internal angles)
• Matte and frosted finishes inspired by classic GF style
• And importantly: the movement architecture is built forward, upward and outward—designed visually for the wearer, not the caseback.

This is pure artistry in motion.

Wearability (On-Wrist Experience)

This is the first Greubel Forsey where the phrase “daily wearable” is not an exaggeration.

The titanium case makes it shockingly light. The Convexe curvature hugs the wrist in a way that feels natural, almost organic. The integrated rubber strap is soft yet supportive, giving the watch a sporty, modern vibe.

Despite its complexity, it’s never overbearing. It draws attention, yes, but not in a showy or ostentatious way. It’s a piece only collectors recognise—and they will recognise it instantly.

Comfort?
Better than many steel sports watches. Seriously.

Finish, Details and Touches

Greubel Forsey finishing is legendary—and not as a marketing phrase. The level of handwork here is beyond what most collectors will ever see elsewhere:

• Sharp internal angles hand-cut into titanium
• Black-polished steel components (so perfect they reflect like obsidian)
• Multi-textured bridges combining frosting, brushing and mirror finishing
• Geneva-level anglage multiplied tenfold
• Laser-sharp engraving
• Layered depth giving the watch a sculptural dimension
• Even the rubber strap integration is seamless and elegant.

Every component, every screw, every bridge feels as if it has a reason to exist—and a story behind it.

Value, Rarity and Market Position

Greubel Forsey watches exist in a micro-category of their own: ultra-high-end independent horology with microscopic production numbers (well under 200 watches per year across all models).

The Double Balancier Convexe Titanium is:

• Extremely rare
• Highly sought after by serious collectors
• A showcase of one of GF’s signature mechanisms
• Part of the brand’s modern, more wearable design era
• Its price reflects this positioning: it sits in the £280,000–£300,000+ region, depending on configuration. But in the world of high-end independents, where demand outstrips production, this feels aligned with its technical complexity, finishing and reputation.

A Greubel Forsey is never about hype; it’s about collecting the very pinnacle of what modern watchmaking can do.

Conclusion (Our Verdict)

The Greubel Forsey Double Balancier Convexe Titanium is one of the most compelling expressions of contemporary haute horlogerie. It blends technical audacity with sculptural beauty, wraps it in a wearable titanium case, and delivers a movement that feels alive on the wrist.

It’s not just a watch—it’s a statement of intent.
A mechanical manifesto.
A reminder that some makers aren’t competing with anyone but themselves.

If you’re looking for a watch that embodies the highest level of finishing, engineering imagination and three-dimensional presence, this is one of the most extraordinary pieces you will ever encounter.

A masterpiece in every sense.
