This is a very large and rather clean vintage 1970’s Wittnauer chronograph measuring 40mm. in stainless steel. The case has NOT been polished and retains its detail. The mesh bracelet is generic and looks great on the watch. This dial and handset is all original and very clean. The manual winding caliber Valjoux 7734 movement was cleaned and is accurately keeping time with the chronograph function operating smoothly. This watch will draw many eyes to your wrist.
