Armin Strom, a brand whose founder is best known for his expertise in skeletonizing and engraving timepieces, introduced their first totally in-house manufactured skeleton timepiece at Baselworld last month.

The Armin Strom One Week Skeleton is powered by manually wound caliber ARM09-S runs at a rate of 2.5Hz and has a 7-day power reserve. This is not your typical skeletonized movement, as each piece requires 4 days of hand engraving and another 3 days of hand finishing. The main plate is fully skeletonized, as are gear-train bridges and barrel bridges. Moreover, the components are all decorated with classical hand engravings.

The One Week Skeleton is presented in an 18K rose gold case measuring 43.40 mm by 13 mm. The dial ring is in sapphire with founded applied indexes. The hands are rose gold (with luminous material for the hour and minute hands). Functions include hours and minutes indications in the center; and small seconds and power reserve indications in the subsidiary dial at 9 ‘clock. The dial and caseback are protected by anti-reflective sapphire crystals. The ridged crown is in solid 18K rose gold and is embossed with the Armin Strom logo. Water resistance is 50 meters.

The Armin Strom One Week Skeleton is delivered with a genuine black or brown alligator horn-back strap and 18K rose gold ardillon buckle, as well as an additional black or brown rubber strap (a double-fold clasp in 18K rose gold is available on option). Retail is $49,900. This is a very special piece, considering the brand’s heritage in skeletonization and engraving, and it is limited to 50 pieces.
