Tissot T-12 Navigator 24 hour watch - casing help


Recommended Posts

Hi,

 I have partially restored a Tissot Navigator T-12, the 24 hour version however when I tried to case it back up there was too much movement inside. The movement can move about 1mm forward and back towards the case back. I have a movement holder ring however I cannot find any guidance on whether it is the correct one. Or how it should look if serviceable. 
does anyone have a photo of the case parts for this watch or similar. I will post photos. As you can see, I am using a couple of non-standard spacers forward of the dial to get the right tension.

Background history would be nice? In other words wasn't functional before the partial restore?

Then I found a link which has a picture of the movement inside the case I can't tell from your picture whether you have the movement ring with the two screws locking everything in place?

Then does Tissot Have anything that resembles a model number or a case number on the back of the watch?

Sorry, I collected 3 watches that were all in pretty bad shape and was able to recover enough to build one watch. Two watches had plastic movement rings that were in such bad shape they practically fell apart. The third was the metal one that you see in the photo. None of the watches had any other spacers or rings.

Thanks for the link. From looking at the photos, I think there is a ring spring missing that fits into the case back. That would make sense. 
cheers

Ok, so the answer is that you need the movement holding washers to pass over the movement holder and clip into a groove in the inner wall of the case. That holds the movement in exactly the right depth so stem fits perfectly and dial is right distance from crystal. So nothing to do with spacers etc. 
Watch is now a pleasure to wear. 
Cheers

    • Hi nickelsilver, thanks for the great explanation and the links! I'll take a good look in the article.  Especially this is great news to hear! Looking through forums and youtube videos I was informed to 'fist find a case and then fit a movement for it'. But seems that's not the case for pocket watches at least?  I guess I should be looking to find some 'male square bench keys' for now. I was thinking of winding the mainspring using a screwdriver directly, but I found a thread that you've replied on, saying that it could damage the spring. 
    • Murks, The rate and amplitude look OK, and the amplitude should improve once the oils you have used get a chance to move bed-in, also I notice that you are using default 52 degrees for the lift angle, if you get the real lift angle (assuming it's not actually 52) this will change your amplitude - maybe higher, maybe lower. I notice that the beat error is a little high, but not crazy high. At the risk of upsetting the purists, if the balance has an adjustment arm I would go ahead and try and get this <0.3 ms, but if it does not have an adjustable arm then I would probably leave well alone. Just my opinion.
    • Hi everyone on my timegrapher it showing this do a make anymore adjustment someone let me know ?    
    • Maybe I'm over simplifying this and I'm a little late to the discussion, but just by my looking at oil when I use it on a treated cap jewel  the oil stays in one nice bubble, but when I don't it spreads out to the edges of the jewel. I'm not sure (but could well be wrong) but the analogy of a waxed car and rain is accurate in this case, the wax is very hydrophobic and repels the water, however, the process epilame works by is a different physical process based upon cohesion/adhesion (oleophilic) not repulsion (oleophobic)  at least as far as I have read/observed. If one were to use a oleophobic substance equivalent to wax (hydrophobic) then one would need to create a donut shape to fence in the oil, however if one used such a strategy with a epilame which is oleophilic then the oil would sit on the ring of the donut and not in the 'donut hole', exactly where you don't want it. Even if the oil is smeared then the oleophilic epilame should pull it back to the center (see diagram below). Reference For interest the chemical in epilame is 2-(PERFLUOROHEXYL) ETHYL METHACRYLATE, CAS NO: 2144-53-8
    • Looks lint the teeth on the hour wheel aren't meshing with the teeth on the calendar intermediate wheel, maybe the hour wheel is sitting on top of this instead of meshing?
