The new Harry Winston Ocean Sport Chronograph Skeleton (ref. OCSACH44ZZ001) is presented in a case made of rare (at least, in the world of fine watchmaking) zalium alloy. The automatic chronograph not only looks great but also offers a surprisingly good (at least, for a skeletonized timekeeper) level of legibility.
It is not the first time that the American jeweler dives into the world of unusual alloys. Last year, for example, we have already seen the sporty Ocean Zalium Limited Edition ladies watch.
This year (or, to be more precise, next year, since the brand plans to officially introduce the watch during either SIHH 2012 or Baselworld 2012 trade shows,) Harry Winston presents yet another wristwatch in the same lightweight and highly corrosion-resistant alloy of aluminum and zirconium that enjoys a great level of popularity among the rocket science crowd.
Somehow reminding to yours truly of the highly expensive Breguet Marine Royale 5847 alarm watch that was presented almost three years ago, the new Harry Winston Ocean Sport Chronograph Skeleton sports a peculiarly notched unidirectional rotating bezel with the usual diving scale.
To make the scale more readable in broad daylight, HW covered its minute markers with scratch-resistant black DLC coating.
Like many recently introduced high-end watches, the Ocean Sport features a skeletonized dial, which is covered with a smoked sapphire crystal to provide the view at the unspecified automatic caliber that power the watch.
As you can see on the image, the calendar ring is also skeletonized and is only readable thanks to some white part, which is put behind the date aperture at 12 o’clock to serve as a background.
While skeletonized timepieces are normally barely legible, I must admit that this one is easy to read thanks to patches of Superluminova that cover its hour and minute hands. The central chronograph seconds hand is, too, legible enough thanks to its electric-blue color.
I especially like the way that Harry Winston solved the usual problem of visually separating the chronograph and small seconds sub-dial: there is not small seconds sub-dial at all! The seconds hand looks like it almost floats in thin air, while the 12-hour and 30-minute chronograph sub-dials are equipped with prominent disks.
Although Harry Winston preferred not to disclose the name of the caliber that powers the wristwatch, I think it would be safe to assume that the watch is animated by an ETA chronograph movement with my bet being on a something natural-born like ETA 7750 rather than a simple ETA 2824 three-hander with a chronograph module.
