Wittnauer Professionals with Valjoux 72 variations are quite rare and desirable. The Roulette model with the correctly signed movement, untouched condition and tropical dial make this one a collectors piece. It was in my collection and aquired years ago from a good friend. The watch works well, condition of the case is original and has signs of wear.
