This is one of the nicest 1960's UG Tri-Compax Moonphases I ever saw! The case is unpolished and all the numbers are clearly visible (ref 881101/02)! Normally the numbers are worn/polished off... The original dial is very clean and untouched. The bezel is also in super condition and only has a few minor spots. The UG Cal. 281 movement is in pristine condition and working perfectly and retains the original crown. Attached is a new period style strap with original UG buckle. These are fantastic complicated watches, especially in this condition!
