Hello, great info. I have one of these watches with the Marvin movement.

the Crystal has turned yellow due to age. My question is can this be changed easily the dial is in excellent condition it’s a pity to hide.

regards John

You can easily polish an acrylic crystal using toothpaste, perhaps with a bit of backing soda. Replacing is normally advisable only when it's cracked, also because most collectors appreciate full originality and patina.

BTW, we have a section here where it's considered polite for new members to introduce themselves first.

Hi and welcome to the forum,   In addition to jdm's Baking soda/toothpaste the use uf Jewelr's rouge and chrome polish (Autosolvol) will do the job it just needs the application of elbowgrease. and time.

Hello. Thanks for the information. I will try the autosolvol. Just as a introduction I am a 76 year old who has a collection of many watches mostly mechanical. I do collect quite a few trench watches. I blame my father for my  for my interest in clocks and watches. He gave me his retirement watch and my grandfathers pocket watch plus his mantle clock all still running well. Take care all. John.

    • Thanks for the replies! Here's a photo of the front of the clock and a GIF animation of the movement (exposed by removing the black cap in the centre of the clock). You can see the behaviour of the gears. It's a fairly valuable clock from the 80s (Braun ABW 35). I'm not sure if replacing the movement would diminish the value, so I'd prefer to keep the original parts if it's easy to fix. But since the movement itself is pretty generic, I guess, maybe replacing it wouldn't make any difference with regard to the value of the clock? Or would it? I suppose the value is mostly in the design.
    • Well, my fundamental stance is that I want to go in and out without leaving any trace other than a shining, perfectly running movement. So, no scratchings on the inside of the case back lid, no marred screws, no debris, no fingerprints, and so on. That is, my goal is to make it impossible for the FBI to track me down. As a professional, I suppose you might want to keep track of returning watches, but as @JohnR725 mentioned, we can keep detailed computer records without marking the watch at all. That may not be true for every watch, but luxury and COSC-certified movements do have unique numbers. John also says it’s best to leave no sign you were ever there, and I couldn't agree more. Now, suppose the Sea-Dweller I'm working on is one day scrapped, and you want to sell the case-back separately (perhaps the case was destroyed in a plane crash). Then the scribbles on the inside no longer reflect the current movement inside the case. Also, the engraving will likely halve the market value of the case back. It had been "sleeping" for about a week and a half. Yes, the "debris/old lubricant" theory is my hypothesis as well! It will be interesting to see what I find once I have time to start disassembling the movement.
    • I've repaired a few of these, having some success with stripping and cleaning the mechanism.  They are so cheap though, its hardly worth the effort in many cases.
    • Get well soon Old Hippy, torn muscles.,  not good
    • Id love to see how he has the output shaft mounted to this setup, as I have the same rotary stage and stepper in my build.
