    Even a Luddite like me could follow that - Thanks for a very informative read. A lot of work went into that, I'm sure!

    Thanks v. much. I've been looking at a 3133, and this helps.

    Best wishes,

    Did you notice whether the pushers were in the same relative position (height and distance) to the stem? Also, when you say that with the calendar parts removed, there is a bit more stem height, would you care to guess how much, in particular, do you think that there is .2 mm or less difference? (With a very small difference, after the calendar bits are gone, one might get things to fit by adjusting the dial thickness. One can lose .1mm of a dial without any problem, and, perhaps, .2mm, although that's pushing it.)

    Best wishes,

    Fantastic and informative post!

    However I have to say that 3133 movement looks ugly compared to swiss one.

    Great review and even greater pics, thank you for your time and efforts.

    I have a SECONDA chrono of the early 70-ies with ????? 3133 inside, a great watch, keeping great time, ready to withstand whatever daily challenge and real heavy duty. Not costing the earth, either. Love it tons...

    Great pictures / read.

    Always wondered if the 3133 could be used to replace a defective 7734, shame they are so different.

    Cheers

    I have bought my Poljot Luftwaffe with 3133 mouvement in 1999 and it still works accurately without any rehaul since. Maybe it's time to give it to my horloger.

    Wow, how interesting, top work

    Wow, did a search for the movement here, since I've been curious about it ever since I bought my first mechanical Junkers sometime in the early 2000s. Just took it out, rewound it and off it goes.




    As you can tell, it was a trusted beater for years until the strap died and I somehow went back to the Casio I had. I still love the view of the mechanics.
