Hi Charles, I had a dig, but could only find info on the current clocks that receive time info on an ARINC 429 serial bus, and an earlier hybrid LCD / mechanical model that needs an external 1PPS (I'd like one of those). I've never seen an aircraft clock that needed an external 60Hz signal. Unfortunatly Hayden have been bought up and no longer list instruments. Keep Googling!
