I bought this watch a few months ago and although it's not my usual style (late 60's /early 70's) I really like it. Even its modest proportions - 33mm exc crown - can' t keep it off my wrist. What really impresses me about this watch is the waffle dial, it's beautiful and in great condition. The seller said he thought the movement might be a Felsa Bi-Dynator and thought the watch dated from late 50's or early 60's. This is my only Wittnauer and I have to confess my ignorance about the brand and about this watch, does anyone have information on either?
