Helvetia Swiss wristwatch 1930s luftwaffe bombers watch. The watch is large (42mm) in full working order. It has been serviced and maintained and keeps time well. The crown was replaced when the watch was serviced. The watch is almost a hundred years old but can be worn with any nato style strap and looks bold due to its size. The watch is wound manually, 10 rotations is enough for a day of use, it tends to run about 2 minutes fast over the course of 24 hours which is acceptable for a watch of this age and is easily adjusted when winding if worn daily.
