You were correct about the Marlin. Had a brain fart. Her is a picture of the other on in the Timex Catalog.

You should give it a try. It may just be gummed up. So a soak of the movement in Goo Gone may be all it needs. If not a front loader, pop case, remove retainer spring or other retainer. Pull set stem out then find out where its release is. Many just have a screw to turn maybe 1 1/2 turns. Turn too much the screw comes out. A pain to start back in. Now movement with dial face and hands can be removed. Hands will pop off with thin blade like exacto knife or buy an inexpensive tool.

Watch face probably has 4 brass tabs holding it to movement. Go slow and easy with these. They can break off.

Then soak overnight. Dry. There are oil cups you can put a drop of watch oil. Then do all backwards.

All the service manuals are online. Google Timex watch movement #25. Actually, kinda fun.

Good luck. If I can be of any assistance, let me know.

There are some online videos for fixing the plastic bezel. Believe they used small amounts of fiberglass to repair. I too am looking for a particular bezel. I have a source I may be able to send. Copied you handle. The link I have for above document is

Have you tried to restore Timex watches before.

This was on a page labeled " Timex Skindiver Series and Sport Series".

If you can find out the movement number, you may be able to back figure. Perhaps a movement #25 first produced 1965 I think. There is an online document for "Timex Series". I will send link if I can find it. Gonna try to attach picture from that document.

Believe the one on left is a Sprite. Have one just like it with the numbers to the left being 26951. See Heritage 1854 document on line.

Very nice! My favorite field watch is a vintage 70s Timex Automatic Viscount with elapsed time ring. About 47 years ago, one was on my wrist in about every swamp in south Alabama and northern Florida doing grad school work. It finally quit a few years ago. Used its corpse to learn how to refurbish vintage Timex watches. Example is attached.
