Functionality: Fully tested and working! Winds smoothly, starts/stops via the top crown pusher, and resets cleanly back to zero using the side button. Crystal: Has a visible crack across the front crystal/glass (see photos) Dial: White analog dial face showing some light vintage age, including minor dial discoloration and faint circular hand-drag marks from use. Case: Chrome-plated metal case with standard light wear consistent with age. Selling as-is due to the cracked crystal, but the mechanical movement itself runs great! Perfect piece for a collector or someone looking for a working Swiss vintage stopwatch
