I guess the Spaceviews are probably the most sought after Accutrons...judging by the number of conversions that are out there.

Even in the genuine Spaceviews, there are several dial styles; some have chapter rings, while others do not. Hands vary as well.

All 214 suffer one problem: they were originally designed to run on 1.3 volt mercury button cells. When mercury cells were phased out in the mid 1990s, owners had to switch to the modern Silver Oxide cell of the same size, but these run at 1.5 volts; sometimes this results in the Accutron running very fast or not all. Over the years, various solutions have been put forward ranging from altering the internal electrical components of the watch to creating a special battery. In the latter case, the Accucell is the best known. But in my experience, almost all 214s can be made to run on a standard 1.5 volt Silver Oxide battery with very careful adjustment --- with no need to alter the watch or the battery.

The last photograph is my favorite 214 Spaceview!
