Grand Seiko Debuts the Kodo Constant-force Tourbillon

Grand Seiko’s Kodo Constant-force Tourbillon represents a stunning mechanical achievement that sees the constant force mechanism integrated into the tourbillon cage.

Grand Seiko introduces the T0 Constant-Force Tourbillon Movement

A tourbillon is not uncharted waters for Seiko, as evidenced by the Credor Fugaku Tourbillon of 2016. The extremely rare, and modestly unattractive, Fugaku was something of a statement, as much about its ornate case and dial as the mechanics. Now an independent brand after being spun off from its parent, Grand Seiko has just announced a movement that squarely emphasises on timekeeping, the T0 Constant-Force Tourbillon. Announced as a concept movement – with no plans for commercialisation publicly revealed – the movement is Grand Seiko’s first equipped with a tourbillon, and also marks the first time Seiko or any of its brands is utilising a constant-force mechanism. The T0 disassembled Initial thoughts It is not often Grand Seiko launches a new and truly novel movement; this year has seen a few. The recent 9RA5 Spring Drive and the 9SA5 Hi-Beat automatic are interesting and practical movements that will be found in future models. On the other hand, the T0 tourbillon stakes a claim of technical prowess oriented rather than practicality, a claim bolstered by the remontoir constant-force mechanism integrated in the tourbillon cage. While Grand Seiko’s integrated remontoir constructed is patented, this is not exactly novel. Precedents in the watches of IWC and Andreas Strehler, for instance. While each of these executed the idea of an integrated constant force differently, all share the common approach of a one-second remontoir. In short, the Grand Seiko construc...

The RM 72-01 is a first for Richard Mille – a relaxed, playful flyback chronograph that, while as interesting and eye-catching as its siblings, is quite a different mechanical beast from the others thanks to its in-house chronograph movement with a variety of new elements and even a world-first in watchmaking.

Pre-Basel 2015: Arnold & Son Constant Force Tourbillon

Ever since the invention of the earliest water clocks, physics and gravity have affected our efforts to measure time precisely. Liquid-filled clocks ran faster when full, because higher pressure at the bottom of the vessel caused the water to drain more quickly. Springs provided a technological step forward, but not a complete solution, because they […]

Greubel Forsey’s Beach-Ready Balancier 3

Greubel Forsey’s Balancier Convexe S² recently took its final bow, making way for the ‘baby blue’ edition of the Balancier 3. Positioned as the brand’s entry level model now that production of the the dressier Balancier Contemporain has concluded, the Balancier 3 is a 22-piece limited edition that introduces a novel finishing technique for the Y-shaped titanium bridge that transverses the dial. Initial thoughts For fans of sport watches who thought the end of the Convexe S² might be a signal that Greubel Forsey is backing away from its Convexe collection, the launch of a new - albeit limited - series of the Balancier 3 is welcome. The brand’s sporty case format debuted shortly before controversial tenure of former CEO Antonio Calce, who seemed to see the Convexe case as a vehicle for rapid growth akin to that of Richard Mille. But his efforts at scaling production ran into the immutable limits of hand craftsmanship. His ouster was followed by something of a return to form for one of the leading lights of La Chaux-de-Fonds, which subsequently backed away from some of the more simplified watches launched under Mr Calce. The Balancier 3 manages the difficult task of being a casual watch built with utmost dignity. While this is technically the brand’s entry level watch, and a sport watch at that, it is finished more thoroughly and to a higher level than most grand complications from the great houses of Geneva. If we’re splitting hairs - and at this price ...

Hands-on – The New, Blue-Toned Greubel Forsey Balancier 3 in Titanium

Greubel Forsey has always been synonymous with highly complex, intensely finished movements presented as three-dimensional mechanical sculptures. In recent years, the brand has explored a slightly more “restrained” yet modern approach with models like the Balancier S and, more recently, the Balancier 3 introduced in 2023. The time-only Balancier 3 retained the brand’s signature depth […]

Introducing: The Final Versions Of The Greubel Forsey Balancier Convexe S²

Goodbyes are never easy. Nevertheless, after five years in production, Greubel Forsey is removing the Balancier Convexe S² from the catalog. The brand follows this strategy to maintain extreme exclusivity, preserve high secondary-market value, and ensure a focus on innovation and hand-finished quality over mass production. The two farewell creations - one in black ceramic […] Visit Introducing: The Final Versions Of The Greubel Forsey Balancier Convexe S² to read the full article.

First Look – The Final Editions of the Greubel Forsey Balancier Convexe S² now in White or Black Ceramic

Within Greubel Forsey‘s modern catalogue, the Convexe collection has become one of the brand’s most recognisable showcases of its approach to watchmaking. Revealed in 2019, the Convexe case introduced a double-curved construction, designed to follow the natural shape of the wrist and presenting the movement as a sculptural object. The Balancier Convexe S² first appeared […]

Greubel Forsey Bids Farewell to the Balancier Convexe S²

Greubel Forsey’s entry-level sports watch has been in production for five years and is now at an end. The brand is saying goodbye with a pair of final editions, the Balancier Convexe S² in ceramic. The first version is entirely in white ceramic, and the second is black ceramic with the bezel and case back in 18k red gold. Each limited to 11 pieces, the two editions share the same movement, but decorated differently to match the case. It’s manual wind, time-only calibre that is anything but simple; the movement is equipped with the brand’s trademark inclined balance wheel as well as titanium bridges and plates. Initial thoughts A bestseller for Greubel Forsey when sports watches were all the rage, the Convexe line (and related sports models) is gradually being reduced. The Balancier Convexe S² is one of the few sports models that Greubel Forsey has launched since the change in management resulted in the pivot towards more classical watches, exemplified by last year’s Nano Foudroyante. It might be also one of the last: Greubel Forsey notes besides the end of the model’s production, “[this year] also marks the beginning of a gradual transition toward an almost entirely new collection”. While this change in direction has been welcomed by many enthusiasts who appreciate Greubel Forsey returning to its root, the Convexe watches do have their charm. The Balancier Convexe S² illustrates this – the case is large but ergonomic and wearable, and the sporty constru...

New: the closing chapter of the Greubel Forsey Convexe S2
