The six watches which express the extraordinary technical prowess of tourbillon with their inventive presentation. By Hiren Kumar Bose
Harry Winston Histoire De Tourbillon 8
In a vast space, which encompasses half of the watch, two large tourbillon cages are engaged in a constant dance. Every 75 seconds, each tourbillon completes a rotation on a 30-degree inclined axis. Nested within this movement, a second cage turns on its own axis, completing a rotation every 45 seconds. Within the latter, the balance wheel keeps the tempo at a frequency of 21,600 vibrations per hour. With two biaxial tourbillons, the trajectory of its regulating movements is that of a disc inscribed in a sphere. The two rapidly rotating superposed barrels guarantee that the watch has a continuous run time of 55 hours. Comprised of 117 components, each biaxial tourbillon weighs no more than 0.76 g. Each of their two regulating movements operates independently. The movement’s unusual dimensions (43.5 mm diameter) necessitate a sizable watch case. And yet, although the watch case measures 51.0 mm in diameter, it is rather thin: (a mere 17.30 mm). These proportions give the timepiece a relatively delicate and harmonious appearance. Nevertheless, they must be unified, so that their deliberately independent mechanical operation results in a single time measurement. Available in 2 colour variations, each version is an exclusive 10-piece limited-edition.
HUBLOT MP-09 Tourbillon Bi-Axis
The manufacture’s first attempt at a multi-axis tourbillon, the same is showcased in a unique case which provides maximum visibility of its fascinating double rotation tourbillon. Equipped with a 5-day power reserve, the bi-axial tourbillon makes a full rotation in one minute along one axis while another makes its full rotation every 30 seconds overcoming the effects of gravity in more multi-pronged fashion than an ordinary tourbillon. One can admire the MP-09 Tourbillon Bi-Axis mesmerising orbit through multiple angles. The hour and minute indicators are quite obviously displayed on the top right portion of the “lightbulb” but less obvious is the date indicator on two arcs just beside it –the back panel highlighting the numeral.The date corrector lever actuated on the left side of the case makes date correction easier than the usual complete cycling through 31 days to get to the correct date. The power reserve is easy to read as well.

The watch features 3 sub-dials at the 4:30 and 7:30 position. But the additional “Grand feu” enamel sub-dial at the 12 o’clock position – which shows the time – adds an interesting touch to the aesthetics of the timepiece as well. However, the greatest highlight of the watch lies in its movement and the complications. The watch is powered by the proprietary Calibre SXH2, a manual-winding movement that boasts a power reserve of approximately 60 hours. The watch comes with several features, which includes a one-minute suspended tourbillon, a dual time-zone indicator, a day/night indicator, as well as a power reserve indicator. The 43.5 mm watch is available in two different metals: Platinum or 5N Rose Gold
JAEGER-LECOULTRE Duomètre Sphérotourbillon
The Dual-Wing concept enabled the brand to create a tourbillon with precision adjustment. The small seconds can be reset to zero according to the flyback principle by using a push-piece located under the tourbillon at 2 o’clock, without stopping the function of the regulating organ. The small second’s hand is reset and immediately continues its course, accurate to within a second. A multi-axis tourbillon revolves around the axis in its titanium cage in a traditional manner then turns around a second axis tilted at 20 degrees. The combination of these two rotations (30 and 15 seconds respectively) enables the watch to defy the effects of gravity in all positions. It is powered by the in-house calibre 382 mechanical movement. A 24-hour subdial on the upper part of the dial serves to display the time in another time-zone.
HUBLOT Techframe Ferrari 70 Years Tourbillon Chronograph
The thin-and-long-looking watch has been conceived by the Ferrari Design Center in Maranello and built by Hublot. The 45mm wide and 14.80mm thick watch is powered by HUB6311 caliber with 253 components. A tourbillon monopusher chronograph, it runs on 3Hz and offers five days of power reserve. The movement looks high-tech and cool both in its colour and architecture with its bridges treated with ruthenium anthracite. The “lattice structure” cases from Hublot – Techframe is sexier and wearable. Available in titanium, carbon and King Gold version– all are limited to 70 numbered pieces each.
