Repair help on MB Nicholas Rieussec

Recommended Posts

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!

    • Many thanks for your advice (being borne in mind at present) & offer Dell. When I was given the clock the plastic anchor was loose on the arbour (it had split at the 'hole') &, after repairing this, I have been trying to determine whether the spindle (pin) should be perpendicular when the pallet is sitting on a flat surface; or whether, when installed, its L-R extremes (or alternatively its tick & tock points) should lie at equal angles from the vertical when moved with spring absent. I can get the clock to run but in every such configuration the top block has to be turned anti-clockwise (from above) by quite a bit in order to be 'in beat' & it always runs fast (despite the pendulum being set to as slow as possible). This makes me wonder if there is any particular feature of/fault in a torsion spring clock which determines which turn direction (if any) is necessary to get it 'in beat'; & whether there would be a different set of settings that would get it running nearer to time at somewhere around the mid timing/inertia position which would then allow tweaking of the fast/slow setting.
    • Now this has happened I bet China or India just to name two will start to produce none genuine parts.  I did. But idiot Boris Johnson failed miserably in his negotiations. The E U stitched up the UK like a kipper. Nigel Farage  offered his help but big head Boris declined. So this is why we are in this mess all because Johnson wasn't clever enough.  
    • Hands up all those who voted to leave the EU 😂, oopsie.  UK has just signed the Hague convention, next year that will provide cross border clout to British courts.
    • Ive heard about that oil before for the lever pins. I found it easy to work on , it didn't have a whole lot of pivot wear but i bit sloppy on the lever cock, i think you have to live with what you have or bin it. Stiff to wind and set ?  Not a cannon pinion issue that has no friction thats made up further back and if I remember the barrel drives the hour wheel. No problem on this one .Let me know when you start it as i have another that donated to this one, i can work alongside you with it, two heads are better than one.
