Men's Skeleton Watches

Gears, springs and the swinging balance wheel are on full view in men's skeleton watches, whose openwork dial reveals the movement instead of hiding it. Some are hand-wound and need winding by the crown roughly once a day, others are automatic. Open-heart designs take a lighter approach, with a single window over the balance.

These mechanical pieces come from Eichmüller and Riedenschild, in stainless steel cases with silver-tone, gold-tone or rose gold-tone finishes and leather straps in black, brown or red. Several have a see-through back as well. Other self-winding models are under automatic watches.
