Moonphase complications are lovingly collected by watch enthusiasts worldwide. This Butex 35×43.5mm rhodium-plated case is pristine. The original day, date, month, and moonphase dial really looks excellent, considering it is from the 1950s. 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 1950s moonphase.
