Hi all, I am a newbie here. Currently I am having problems repairing my MB Nicholas Rieussec watch. As this had a Minerva movement and had little experience. I am facing problems on removing the chrono disc. Conventional Chronos uses needle, however this model uses a disc to register the timed lapsed. Does anyone have any experience or advise on the disc removal and installation. Thank you in advance to your kind input.

Kind regards.

Hi Leecbo,

It's unlikely anyone has had one of these across the bench, I imagine they go back to the manufacturer in general if in need of service. I would say that if one is comfortable enough with repair work to dive into an automatic chronograph of unique design it'll be pretty evident how they are attached once in there. My guess is they are pressed on to pivots, and the safest way to remove them would be to slide some watch paper under them and then lift off the dial, pulling the discs with it.

How far into it are you? Can you provide some pics?

Hi Nickelsilver.

Appreciate everyone's kind input, in fact the watch is with my watch maker now. You did mention, This movement is of an unique and modern design and most watch smith will not have much or any prior experience on the removal/installation of the timed lapsed counter/disc. however I feel its a good try to explore the repair on this design.

From the attached photo and looking at the disc, I do agree with you those are press fit and I believe proper removal will need a designated puller with the claw place into both the hole of the disc, claw on the underside inwards towards the center and acting the fulcrum force on the pivot pin to exert to upward force to extract it.  

Am I in the right approach? Any further input are most welcome. Thanks in advance. 

Kind regards.

Hi Nickelsilver and all..

Thank you for your valuable insight and the photo of the puller. I will look into the extraction and update of any progress.

Any other further help or suggestion to this issue, as other method or tools applicable/ available are greatly appreciated.

Many thanks for all your great contributions.

Kind regards.

Leecbo.

Also consider using something simple like the Bergeon 6938. These are very inexpensive little pieces of durable plastic designed to protect a dial when removing hands. However they might also be ideal for sliding under your discs thereby exerting an even pressure on the underside of each disc for removal with some simple leverage.

Whilst it's not your exact model of Nicolas Rieussec you might be interested in this video...https://www.youtube.com/watch?v=ZshUb8HEZ_8  ... especially about 30 seconds in!

      Unfortunately I'm not that lucky. I started on the train side and after I noticed the binding I pulled everything out except the driving wheel to rule everything else out. It still binds. I'm going to double check that the pinion is fully seated on the staff first, then if no joy I'll push the bridge jewel up a fraction of a mm. Fingers crossed!

      Thank you for the advise!! It worked. The setting screw was a lock/unlock to remove the rotor.

      I have that French tech sheet too, it is a little different than the English one (eg, it doesn't have the auto works diagram). BTW, it looks like you are looking up the case number in the 1979 ABC supplement. The 1974 ABC catalog does have the 3093 case. As you determined it takes the 1222-5 crystal.  When I serviced my President 'A' (which also takes that crystal), I was able to fit a 29.8 crystal from my DPA crystal assortment. Those are, in my opinion, a great deal. The assortment comes with 10 sizes each from 27.8mm to 32.4mm in 0.2 increments. I pretty much use them for any non-armored crystal that takes a high dome crystal. I think they no longer make them but Cousins has still has some in stock but when I bought them they were around $40 for the set and now they are around $100. Still, at 40 cents a crystal it's still a good deal. For the large driving wheel, I remember I once assembled the keyless/motion works first and when I placed the large driving wheel it was interfering with the setting wheel on the dial side as the teeth were not fully meshing and it wouldn't fully seat. If that isn't the issue I got nothing and am looking forward to see how you solve it 🙂

      Not sure, but just looking at it, it seems like the screw on the right may be a fake? The one on the left may not be a screw in the regular sense at all, rather a 2 position device, I think you need to point the slot towards either of the 2 dots and one will secure and one will open. Like I said this is just my best guess looking at the pictures.
