Block RG Stealth Tourbillon: When Time Becomes Sculpture

Block RG was never conceived as a watch in the conventional sense. It emerged as a gesture — a deliberate rupture from established horological language — and a sculptural exploration of what time becomes when reduced to pure form. Its purpose is not to please, persuade, or conform. It exists with presence and intention.

The Stealth Tourbillon marks the inaugural chapter of the brand’s Stealth Collection, and with it, Block RG asserts a philosophy closer to contemporary art and architecture than traditional watchmaking.

A Volume Shaped by Light

At first encounter, the Stealth Tourbillon presents itself as a monolithic object — sharp, faceted, and architecturally pure. Its form draws inspiration from stealth aviation, where geometry, tension, and surface interaction define both function and identity.

Crafted in either rose gold or titanium, the case expresses two distinct emotional registers. Rose gold introduces warmth, density, and gravitas, giving the sculpture a grounded presence. Titanium, by contrast, offers lightness and modern clarity, emphasizing precision and contemporary restraint.

A multi-angled sapphire crystal completes the architectural intent, creating depth and visual tension while allowing light to refract across the movement beneath. The result is not decorative transparency, but spatial drama — the sensation of a mechanism suspended within a crystalline structure.

A Strictly Limited Creation

Exclusivity is not a marketing exercise here; it is intrinsic to the object’s philosophy.

Only 24 pieces of the Stealth Tourbillon exist worldwide:

  • Eight in rose gold

  • Eight in titanium with a red hand

  • Eight in titanium with a blue hand — already sold

Each watch is individually assembled, adjusted, and finished as a singular object. These are not units on a production line, but autonomous works, each carrying its own presence and subtle variation.

The Mechanical Heart

At the core lies the Block 1 Tourbillon movement, developed in collaboration with Telos. Hand-wound, operating at 4 Hz, and offering a four-day power reserve, the movement comprises 187 components and 29 jewels.

Yet, unlike traditional high-complication watches, the movement does not seek visual dominance. It is integrated with restraint. It breathes quietly within the sculpture, serving the form with honesty rather than spectacle. Hours and minutes are indicated with clarity, while the tourbillon carries seconds and reinforces the sense of time in motion — present but never intrusive.

This is mechanics as architecture’s silent partner, not its centerpiece.

A Contemporary Presence on the Wrist

In the hand and on the wrist, the Stealth Tourbillon defies expectation. It appears strong and imposing, yet feels unexpectedly light. It is monolithic in form, yet refined in wearability.

At 46.7 × 36.7 × 13.9 mm, the watch does not attempt to disappear. Instead, it balances contradiction and harmony — weight and lightness, sharpness and fluidity, precision and emotion.

This is not a watch designed to blend in. It is designed to exist.

A Statement of Identity

Collectors who choose Block RG are not simply adding another complication or heritage reference to their collection. They are introducing a different language — one that aligns more naturally with contemporary art, industrial design, and architectural thought than with classical horology.

The Stealth Tourbillon does not reference the past. It speaks in the present tense, offering a vision of watchmaking where form leads function, where restraint becomes strength, and where time itself is treated as a sculptural concept.

Block RG does not ask to be understood immediately. It asks only to be encountered.

Hublot MP-17 Arsham Splash — The Art of Time in Motion

When art meets horology, time becomes fluid.

The Hublot MP-17 Meca-10 Arsham Splash Titanium Sapphire marks the next evolution of the brand’s creative collaboration with Daniel Arsham — American artist, sculptor, and Hublot Ambassador. Following the experimental MP-16 Arsham Droplet, this wrist-worn sculpture channels the beauty and movement of water, transforming timekeeping into an art form.

Sculpting Time Through the Art of Fusion

Hublot’s Art of Fusion has long been about blending materials, ideas, and worlds. The MP-17 takes that philosophy to a new dimension — merging Arsham’s “fictional archaeology” with Hublot’s modern mechanical mastery.

Every element — from its frosted sapphire bezel to its microblasted titanium case — celebrates transparency, structure, and motion. The splash-shaped dial opening represents a single moment of impact, forever suspended.

The Mechanics of Motion

Powered by the HUB1205 Manufacture Meca-10 movement, this hand-wound engine delivers a remarkable 10-day power reserve, visible through both the dial and caseback. Measuring 42mm across and just 15.35mm thick, it achieves sculptural balance and everyday wearability — a rare combination in Hublot’s MP series.

Green accents — Arsham’s signature tone — energize the hands, numerals, and power-reserve indicator, while the openworked dial reveals the intricate depth of the movement beneath.

The Fluidity of Time

Arsham once described his work as “collapsing time — you’re not quite sure if it’s an object from the past or the future.”

That tension defines the MP-17 Splash. The design blurs the boundaries between liquid and solid, past and present. It’s an exploration of time as a tangible medium — sculpted, contained, and in perpetual motion.

Edition of 99

Limited to just 99 pieces, the MP-17 Meca-10 Arsham Splash Titanium Sapphire stands as both collectible art and high watchmaking. It invites wearers — and viewers — to perceive time not as it passes, but as it flows.

“This collaboration explores the fluidity of time through a case inspired by the perfect geometry of a water droplet,” says Daniel Arsham. “Its transparent structure captures the clarity and motion of water — suspended, precise, and always in flux.”
