Greetings OF fellows, Well, it might be a strange question, the reason for me asking this is that I last year bought a 145.012-67 completely made up from replacement parts (caseband, caseback, dial, hands and movement). I bought it because I wanted to have a spare 321 movement for my other 321 Speedys. Anyway, I am not using the watch at all, saw a for sale post at a Swedish watch site for a 35.70.5000 with an Apollo 11 panda dial. I am thinking about buying the watch, using the dial in my franken watch and selling the 35.70.5000 (the original dial and hands are included). So, what do say, will it be possible to use the panda dial in my watch? Cheers, Hans
The position of the feets on the backside of the dial is different between 321 an 861. So it won't fit.
This is not correct. The feet are in the exact same position on the back of the dial but are thicker and longer on the 321 dial compared to an 861 dial. I've fitted 321 dial to an 861 movement just by trimming down the feet size. However the problem with fitting an 861 dial to a 321 movement is the feet will be too short, they will go into the holes in the movement but not far enough to be able to lock the dial in place.
There's no need to extend the length. You can mount the dial without any modification. Edit: Obviously not correct.
Are you sure? Both @sigguzzi and @pascs says that it can’t be mounted on a 321. What is the truth? I am very confused right now
Or search, since there’s a 99% chance he’s answered it before! Otherwise, the feet are in the same positions.
I didn't know my watchmaker did anything like this when mounting 861 dials to 321 movements for me. He always said it's not a problem to mount an 861 dial to a 321 movement. We live and learn... So I sincerely apologise for my post.
To be clear, I have no idea what your watchmaker did, but if you look at my photo above,you can see on the dial feet for the 321 dial where the dial foot clamping screw has “bit” into the foot. If you were to transfer that mark to the 861 dial I’m pretty sure that would be out in space...
Thank you for this input. While being an engineer, I never asked myself what my watchmaker did exactly.
I feel sorry for having given you wrong information. I have learned by now that it's not possible to mount a 861/1861 dial to a 321 movement without any modifications. Follow this thread and help is on the way...
The method used by the 321 and 861 movements to secure the dials are quite different, the 321 uses a rotating latch to grip onto the dial foot, the 861 uses a screw. The 861 dial feet will fit into the holes of a 321 movement but are not long enough to reach the lock mechanism, they are also thinner so the dial could have some slight rotational movement. You could probably use dial dots to secure the 861 dial to the 321 movement but I've never really thought of that as a professional solution.
Thank you all for your input I now understand that the dial will not fit my 321 so I will forget about my little project...
