This time a Pierce Vitaflex on the bench. A service wasn’t immediately necessary but the amplitude was a bit on the low side and the movement appeared to be dirty. A service never hurts so I decided to go ahead with it. The most obvious thing is, of course, the fact that the hands had no lume left at all. They needed to be filled anew.
I’ve seen some Pierce watches with ETA movements but this one has an in-house movement, the Pierce 105. It’s a hand winder with 17 jewels and this particular one has an Incabloc shock protection. I’d date this Pierce Vitaflex to be from the late 1950s.
