The first watch I tried to rebuild was what I now know to be a nearly irreparable Timex pin-lever. That effort ended quickly in an explosion of tiny gears. My second try was a 7 jewel Waltham. This went better, but I crushed one of the pinions trying to wrestle the wheel train bridge back on. This Enicar here is my third attempt, and the first on a watch I actually like.
I had already pulled the movement from the case when I started taking pictures.
