Review on Mudder Quartz Movement Insert Diameter by Tyler Ramey

It's all plastic but looks pretty good and has nice little details on the face. If you hadn't touched it, you probably would have thought it was metal. I reset this to Daylight Saving Time about 3 weeks ago and it's still showing the correct time. doesn't tick. The main thing is that the diameter corresponds to the declared one. Comes with a rubber ring around the back. I didn't use it as the fit was tight on my project, but it gives you about 1/4" more diameter. When I put it together, it looks like the plastic could be easily broken accidentally. Overall, I would buy again.
