At Salon QP, which is a London-based watch trade show that runs from November 6th to the 8th, Armin Strom launched an all-new open-worked wristwatch collection called the Skeleton Pure.
The Skeleton Pure comes in a 43.40 mm by 13 mm case that is available in either steel (Water), 18K rose gold (Fire), titanium (Air), or black PVD-treated steel (Earth).
Visible through the front and rear sapphire crystals, is Armin Strom’s in-house caliber ARM09-S movement, which has a fully skeletonized main plate, gear-train bridges and barrel bridges. In addition, each version’s main plate has 3D-PVD coating that corresponds to its respective element (water, fire, air or earth). The gear train and barrel bridges feature a rhodium or ruthenium treatment depending on which variation you choose. The escape wheel and pallets made of solid gold with hardened functional areas.
The manually wound caliber beats at 2.5Hz, has 146 components (34 jewels) and double-barrels which provide a superlative 8-day power reserve.
The hour and minute track is on a clear sapphire ring, featuring Armin Strom’s signature off-center design. The small seconds indicator, at 9 o’clock, also features a clear ring. Uniquely, the power reserve level is indicated on the left half of the small seconds subsidiary dial, via a red arrow-tipped hand.
Limited to 100 pieces per variation. Water resistance is 50 meters. Each timepiece includes an alligator horn-back leather strap with contrast stitching and a buckle, as well as an extra rubber strap.
