Moonphase complications are lovingly collected by watch enthusiasts worldwide. This BUTEX 35x43.5mm. rhodium plated case is pristine. The original day/date/month/moonphase dial really looks excellent, considering it is from the 1950’s. I like the horned lugs extending from the case. The manual winding Valjoux 90 movement was just cleaned and all the functions are working perfectly. This is a great example of a 50’s moonphase.
