A new star in the DEFY Skyline constellation is born. The ZENITH Manufacture incorporates a new automatic high-frequency tourbillon calibre into the DEFY Skyline Tourbillon, in two versions in steel and black ceramic.

The tourbillon mechanism has long been associated with the upper echelon of fine watchmaking; a testament to the technical prowess of the manufacture and the skilled watchmakers that bring these mechanical wonders to life. Originally conceived at the end of the 18th century to counteract the effects of gravity on the watch’s precision, ZENITH has given it its own modernistic spin to demonstrate the Manufacture’s unrivaled expertise in high-frequency precision across multiple movement types and functions as well as the edgy design of the DEFY collection – all in an execution suited for daily wear in any situation. Like all El Primero calibres, the DEFY Skyline Tourbillon’s movement operates at a high-frequency rate of 5Hz (36’000 VpH), ensuring optimal chronometric performance with a high resistance to shocks.

Housed in a faceted and highly geometric 41mm case and matching bracelet in either stainless steel or black ceramic, the DEFY Skyline Tourbillon melds the distinctively bold and architectural design of the DEFY Skyline with the mechanical animation of a tourbillon mechanism.

Like the core of a galaxy around which countless constellations are strewn, the central kinetic element of the DEFY Skyline is visible through an aperture on the dial’s lower portion. Fixed to a finely mirror-polished bridge with sharp bevels, the tourbillon cage takes on the shape of an open four-pointed star, with the same futuristic lines as those found in other DEFY references with tourbillon mechanisms.

Turning ceaselessly around its own axis, the tourbillon completes one revolution every 60 seconds. The case’s water-resistance of 10ATM (100 metres) further affirms the all-conditions endurance of the piece.

The DEFY Skyline’s signature sunray-patterned metallic dial with an engraved starry sky pattern has been adapted specifically for the DEFY Skyline Tourbillon, to accentuate the high-frequency tourbillon.

Either in blue for the steel version or black for the ceramic version, the mosaic of engraved four-pointed stars appear to radiate out of the tourbillon at 6 o’clock, expanding as they reach the outer perimeter of the dial.

The luminescent applied markers and hands further add contrast to the dial, with rhodium plated indices for the blue dial and rose gold plated indices for the black dial.

Powering the DEFY Skyline Tourbillon is the new El Primero 3630 automatic high-frequency manufacture calibre, with a power reserve of 60 hours. Mirroring the expansive decoration of the dial-side that emanates from the tourbillon, the Côtes de Genève stripes on the bridges are arranged in a sunray pattern that appear to dart out of the tourbillon. The open star-shaped rotor allows for an open view of the contemporary movement architecture.

Like all DEFY Skyline models, the DEFY Skyline Tourbillon comes on a stainless steel or black ceramic bracelet, with a second strap in blue or black rubber with folding clasp supplied that can easily be switched using the case back’s quick strap-change mechanism requiring no tools.

ARNOLD & SON – ULTRATHIN TOURBILLON Skeleton Edition

ARNOLD & SON – ULTRATHIN TOURBILLON Skeleton Platinum/Red Gold Limited Edition - 2024

 The finesse of curves

With its graceful curves and wide apertures, Ultrathin Tourbillon Skeleton also stands out for its slimness. Its new case, with a diameter of 41.5 mm and a thickness of 8.4 mm, presents the flying tourbillon calibre in its purest expression. 

Click, to see the large size. ▶ BIG FOTO

The Ultrathin Tourbillon Skeleton collection, adorned in red gold or platinum, is issued in two limited series featuring 28 watches apiece.

Arnold & Son continues its tour of the Ultrathin Tourbillon collection. The A&S8320 calibre unveils its curves, apertures and details within a 41.5 mm case in either red gold (5N) or platinum (PT 950), each released in a run of 28 timepieces.

Encased in this precious housing, Arnold & Son’s flying tourbillon stands out for its finesse and precision.

Click, to see the large size. ▶ BIG FOTO 

Finesse, because at just 3.3 mm thick, it is one of the slimmest skeleton tourbillon calibres in existence. Precision, because this one-minute flying tourbillon is assembled with a variable-inertia balance for enhanced calibration stability.

Radiating originality

The purpose of a skeleton is to convey a message, be it geometric, generic or minimal.

For Ultrathin Tourbillon Skeleton, the skeletonisation of the calibre reveals pronounced curves and numerous inflection points that are highlighted by an original finish. 

Click, to see the large size. ▶ BIG FOTO 

On both the Ultrathin Tourbillon Skeleton Red Gold and Platinum, the bridges are treated with rose-gold PVD (4N) after being decorated with radiating Côtes de Genève stripes.

The flange around the calibre adopts this same finish, clearly revealing the Arnold & Son signature at 6 o’clock and enabling the off-centred white opal dial to be displayed in its purest form.

Golden carriage

At the heart of Ultrathin Tourbillon Skeleton beats the A&S8320 calibre, whose architecture and slimness are its principal protagonists. Designed without an upper bridge to minimise its thickness, the calibre is classed as a flying tourbillon.

The variable-inertia balance with inertia blocks ensures more precise calibration over time. The slender triangular carriage is supported by a double arrow, which is actually a counterpoise.

The arrowhead on the staff of the escape wheel serves as a seconds pointer, as the carriage completes one rotation per minute.

Performance reserve

The changes to the tourbillon carriage and regulating organ give the A&S8320 calibre a power reserve of 100 hours.

While this is a larger power reserve than for standard tourbillons, particularly slim ones, it is entirely in line with the performance regularly achieved by Arnold & Son calibres.
