One of my favorite timepieces from Swiss-based watchmaker, Armin Strom, is their Tourbillon Skeleton Air which comes in a matte gray titanium case, and normally includes a gray (shown below) or white alligator horn-back strap as well as an additional gray or white rubber strap. However, this particular piece is (shown above) with a brown horn-back alligator strap, which is a stunning combo. And which emphasizes how a simple strap change can significantly alter the appearance of the watch.
The Tourbillon Skeleton Air case measures a very wearable 43.4 mm x 13 mm, which is a good size for a wide variety of wrists. It is not a 38 mm dress watch for sure but it is also not a 48 mm Panerai. With a non-locking crown and 50 meter water resistance, it is not really a sports watch, nor is it a dress watch with the bold skeleton dial and aggressive appearance. The look is nice with a t-shirt, and while I normally prefer a smaller, dressier watch with a suit, the proportions are just at the cusp of where I think it still looks good with a suit as well. Any bigger, though, and I would not want to wear it with a suit as larger watches are difficult to fit under the cuff.
The manually wound tourbillon movement (caliber ATC11-S) features a full skeletonized mainplate with a gray PVD coating. Thanks to double barrels the power reserve lasts for a duration of 10-days. The balance oscillates at 2.5Hz or 18,000 vibrations per hour and the movement consists of 164 total components, 24 of which are jewels. The finishing includes ruthenium bridges with straight-grained surfaces and bevelled edges, gray PVD coating on the mainplate, and hand-polished screws.
An off-center time display with steel hour and minute hands, and a sapphire dial ring with applied indexes, along with full views of the 60-second tourbillon (at 9 o’clock) and skeletonized components – gives this watch its distinctive face.
The retail is approximately $93,000. (Ref. TI15-TA.50) More info is available at arminstrom.com.
