“A smart buyer’s choice.”

These watches have been carefully used and their overall appearance is excellent. You’ll have to look very closely to find any signs of wear – on the wrist, the watch feels almost like new.

• Case: Minimal signs of wear. No noticeable dents or marks.
• Battery health: Very good, tested.
