The latest timekeeper from the Harry Winston production is the initial watch by the manufacturer that combines tourbillon and jumping hour complications. The timepiece is quite intricate and skeletonized to provide a detailed insight on its modernist architecture inspired movement – manufacture HW4401 manually-wound mechanical caliber with an extended power reserve which is indicated at the rear side of the case. It looks stunningly from both front and back and utilizes a black sapphire for its dial in order to provide optimal exposure of the hand-chamfered steel bridges. Stemming from the Ocean collection by Harry Winston, new Tourbillon Jumping Hour model will be available in two housing materials – with cases made from red and white gold. Both versions are also available with lavish diamond decorations with the total weight of 6.25 carats.
Not only that it is the first Harry Winston watch that combines a jumping hour feature with a tourbillon for the first time, it is also a bit more complex since it features an unusual design. Instead of being placed on the movement mainplate, the tourbillon cage is suspended with two hand-chamfered steel bridges. This gives an appearance that the tourbillon is floating in air and is not connected to the rest of the movement. The hardly notable connection that drives the tourbillon is a wheel geared to its outer edge which is very hard to see and almost completely covered by the lower end of the minute track. The period of rotation of the tourbillon feature which lies between two sheets of sapphire is 60 seconds and this is utilized to indicate seconds.
The upper section of the skeletonized dial is reserved for jumping hours and a minute track. The aperture for hour resides at the very top of the face and it shows current hours which are changed every 60 minutes, while for the minutes, Harry Winston designers used a small red hand which rotates around the minute track. Thanks to the clever solution, the minute hand never obstructs the jumping hours indication. Just like the tourbillon cage (which weighs just 0.49 grams), the minute track is held in place with a series of hand-decorated and open-worked bridges. As the representatives of the brand reveal, the design of the entire dial is inspired by Modernist architecture which utilizes steel and glass as its mediums. The entire architectonics of the watch is supreme and it looks dashing and dynamic from both the front and the back (which includes a retrograde power reserve indication which shows how much power remains in its quite impressive storage that lasts for 110 hours). This extended power reserve is achieved with the inclusion of twin barrels in series.
The entire in-house 41-jewelled HW4401 caliber is constructed from 330 components. Its diameter is 36 mm, while the height measures to 8.62 mm. It operates at the frequency of 4 Hz and includes a variable-inertia balance and a flat balance spring. When speaking about the included decorations, the movement is graced with Côtes de Genève motif, black DLC treatment, micro-blasting, as well as with circular grained gear trains.

On the other hand, finishes of its round 45.6 mm wide and 13.2 mm thick case are polished finish for the housing and the fixed bezel and a satin-brushed finish for the case band. The supported water resistance of the watch is 50 meters, whereas the attachment being used is a hand-sewn matte black alligator leather strap with an ardillon buckle.
Harry Winston Ocean Tourbillon Jumping Hours is available in four versions, each made in a restricted number of copies. Two materials available for the cases are 18K rose gold (200 pieces) and 18K white gold (100 pieces).
