Advice required, Rolex calibre 2135 hairspring collet.


diatribe

Recommended Posts

I purchased a Rolex cal. 2135 fitted balance wheel, staff and roller from a dealer in California. The parts all appear to be authentic, as opposed to generic. However, I have a problem in that the hairspring collet from my original balance doesn't fit the new staff. The diam. of the aforementioned being .5 mm and the  hairspring collet hole being circa .3 mm. I am wondering if there are variations in cal. 2135  balance staff dims. and hairspring collet hole dims.  I can't enlarge the hole in order to fit it to the staff and I don't want to dissemble the new balance and turn down the staff

Will I be able to get a cal. 2135 hairspring with a larger collet hole , if not what is the solution. I would be grateful for any assistance that can be afforded to me on this matter. Thank you.

Im not sure that mixing and matching balances and hairsprings is a great idea, as they are matched at the factory for poise and beat. The best bet would probably be to obtain a balance and spring complete. However, reaming out the collet hole 0.1mm shouldn't pose too much of a problem, as it still needs to be slightly smaller than the balance seat for a friction fit.

Thank you for taking the time to reply to my post. The problem with acquiring a  balance complete is of course the prohibitive price, most of the vendors advertising Rolex parts are attempting to out -retail the aforementioned, in some cases, doubling the manufacturer's recommended prices. 

I had thought of enlarging the collet aperture, but  was concerned with damaging the hairspring. The other option would be to dissemble the roller and turn down the staff with the balance wheel intact. Opening the collet would appear to be the lesser of the two evils, but how would you suggest that I safely secure it in order to do so. The only way I can think of would be by utilising my staking tool set.

I reiterate my thanks  to you for replying and would be further grateful for your advice on the best way to safely secure the hairspring in order to enable me to enlarge the collet aperture.

Just a note, there is no "manufacturer's recommended prices" when it comes to Rolex parts. Their policy is to sell to authorized service centers only. Still, new original parts can somehow be found, sure can be expensive, but unless you take the route above, there could be no alternative for repair.

I fully appreciate that Rolex don't supply parts to anyone other than authorised service centres and was referring to parts asking prices  for the aforementioned. As previously stated, the prices being asked by unauthorised sources are  both prohibitive and unrealistic..

Just curious, how much are we talking about in your case?

Ideally you would use a tool such as this....but one similar could probably be made, or given the size that we're talking about here, even a hand broaching vice might work, such as the second picture. Just be mindful of the hairspring stud and make sure it's not being pinched while holding the collet.

    • 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.
