The outstanding expertise in hand-graving techniques of the Armin Strom manufacture is best showcased in the Manual collection. The timepieces feature immaculate hand-finished details, beautiful flowing designs and top quality materials such as 18k rose gold, titanium or PVD coated black stainless steel. The timepieces also display an open worked dial, while the definitive trademark of this collection is an engraved mountain range scene on the caseback. Some common features of the collection include manual-winding, 5-days power reserve, off-centre time indications and small seconds. The timepieces come on a genuine black, white or blue alligator horn-back leather strap.
