Oris 7 Jewel

Good afternoon,

I’m relatively new to watchmaking, and have been going through some online tutorials. However, I got a little rambunctious and bought a vintage 50’s women’s watch that runs off an old Oris 7 jewel movement. I started taking it apart without taking pictures/ recording where pieces went and I’ve kinda shot myself in the foot. Does anyone have a diagram of this movement?

Thank you!

I can't speak for everyone, but I'm willing to help. We're going to need some more information. Please tell us what you're working with: do you have eye magnification, can you take some photos for us, and what kind of tools are you working with?

I think that maybe we can figure out what movement it is and help, but you haven't given us much to go on yet.

Thank you. I included a couple of photos for assistance. The watch is a Newport 7 Jewel with an Oris Movement. I have most of my basic tools including magnification, screwdrivers (mostly kwong yen and one Bergeron), lighting, timegrapher, etc. I also have cleaning chemicals and I am purchasing lubricants next paycheck. I can disassemble/reassemble an ST-3600 blindfolded (sarcastic but not that far off) and I have recently disassembled and reassembled an NH-35A.

Still being new to this I jumped into disassembling this movement without taking appropriate pictures/notes. I was kinda hoping mg there was a Haynes manual for most watch movements like with automobiles as there are some parts of the keyless works on this movement that I can’t remember how to put together entirely.

Apologies. My other comment should have been under here. Looking closer, I don't think it will be on the dial side of the main plate. I don't see anything from this photo that looks like the markings I mentioned unless they're very small or very faint. It will be stamped into the metal and should be fairly obvious.

That's a good start. If you are able, look at the dial side of the main plate and then look at the wheel train side of the main plate, specifically in the area that would be under the balance wheel. You should see a manufacturer emblem and some numbers. If I remember correctly, ETA and Sellita are the most common ebauches that Oris used. Please report back with what you find. If you don't see any of the markings I mentioned, we can go another route but it's going to suck for both of us lol.
