I found this site while searching for info on HAQ watches and it seems to be loaded lots of great info so I just became a member.
What started my search is that the Accutron 214, that I bought new in 1966, has stopped working and I'm looking for a replacement. I've read info on Seiko, Citizen, Bulova and Certina and am considering the Certina. However I haven't found any Certina's with both a perpetual calendar and a Precidrive movement. Does such a watch exist?
