This is my first post on these forums, so I apologize if I don’t know anything about them. I have a Bulova B5410 and a Pennwood Numechron Model 900 cyclometer clock that I want to work on, but I don’t want to take them apart without damaging them.
The Bulova needs cosmetic restoration, the case is faded and worn, and I’d like to clean it. There’s four screws on the bottom, and what appear to be slots on the back where you can stick something in there and pry the rear cover off with. I'm also curious if there's a way to polish the aluminum bezel in the front, as it's heavily worn out as well.
Now for the Pennwood Numechron. I tried doing research on this particular model, but nothing popped up. It looks like some one off custom build of some sorts. It's rather noisy, and I'm wondering if it needs to be oiled or if the motor is just naturally noisy. There's a total of six screws, four on the feet that appear to hold the metal plate on it to the
wooden housing, and two that hold the clock itself to the plate.
Here's a video of it. It's somewhat loud, as you can hear it from across the room.
