Hi All,

So I've just picked up this lovely old Chronograph from the 60s. It's the first mechanical chrono I've owned so this may be user error, but:

The large second function doesn't reset to exactly 12. In fact, it resets further round the dial each time (it's currently round to the 2 marker)

The large second function will stop at random, which stops the whole movement.

What's going on ere then?!

If I could upload an image without it failing every time I surely would..

Good advice here: https://mb.nawcc.org/threads/resetting-chronograph-hands-to-zero.58491/

Based on your description, I think you have two things going on. The sweep is probably loose, which is why it's inconsistent. As far as the whole watch stopping, that probably just needing a clean and lube, but it's also possible the sweep is interfering with something that's causing it.

      Chinese clone demagnetizers

      I bought a compass to detect magnetism. The magnetic tip reacted to both magenetised and non magnetised basic steel so it became a guessing game as to whether my test subject was either weakly magnetised or dense steel. I've found the best way to detect magnetism is by using the smallest unmagnetised screw and a known piece of unmagnetised steel to test the screw and another piece of known unmagnetised steel to test the first known piece of unmagnetised and another....................... 😂

      Ha ha, reminds me of this: "Don't go puttin' none of that stuff on my sled, Clark. You know that metal plate in my head? I had to have it replaced, cause every time Catherine revved up the microwave I'd pi$$ my pants and forget who I was for a half hour or so. So over at the VA they had to replace it with plastic."

      Need some crystal replacement advice

      By Zendoc · Posted

      Hi @VWatchie - I have model of this Mondaine quartz watch in my collection, just a smaller size. I bought it many years ago, new.  I wonder if  the crystal on your watch is original?  My original crystal was entirely flat.  I scratched it at one stage and replaced it.  There is a dealer located in the UK who sells replacement crystals for Mondaine on the big E - I bought mine from him.  If you PM me, I’m happy to forward the listing details - he may keep different sizes for the Mondaine range?.  The replacement he sent to me was a perfect replacement for the original.   On a side note, the Ronda movement in these is very easy and fun to work on.  They’re also very cheap to replace.  I learnt a lot about the big date complication when the smaller date wheel spring mechanism malfunctioned and the date changing stopped. I stripped down the movement and it went back together very smoothly and continues to work perfectly.  I like the streamlined aesthetic of the Mondiane line.  I also have one of their big date mechanical movements which runs on an SW200-1. The crystal on that is also perfectly flat, btw.   Cheers, John

      I have a DIY version, it’s a voice coil from a 300mb disc drive and a vdu transformer , when you put the tweezers in they vibrate like a tuning fork  and come out clean. Could get an engine block in.
