orient 46941 regulating

Recommended Posts

Hi, 

I tried to regulate the movement from orient 46941, it seems how slow i tried to adjust the reading still the same and time shown average 3 mins faster in just few minutes. Is it the problem lies on the beat error ? By using this software, beat error showed zero, so I eliminate the idea of that...any advice from u guys?

I am kinda new to watch disassemble, in this pic config will I able to remove the balance bridge assy ? I tried to remove but seems something not releasing from lower area , I am afraid to pull due to the hairspring. Do I need to remove any parts frm dial side to release this balance bridge?

High rate / low amplitude suggests that the h/s coils are fouling up on something.

You said that you have cleaned the h/s; when you reinstalled the balance did the h/s coils sit nice and concentric or were they still bunched up as in your earlier photo?

How did you clean the h/s?

Is the h/s sitting parallel to the balance with proper clearance to the balance arms and the cock?

Have you tried demagnetising it?

After several hours of regulating , seems cant get the gained rate lowered...wondering what could be the issue.

Something is fowling the hairspring at a guess. Your original post showed a good amplitude and the beat was within tolerance so something has gone wrong since your adjustments.

Is there an easier way to demagnetise?  I soaked in kerosene and leaving it to dry , repositioned it and anchored down.

Clockboy is right.  Raw kerosine is distilled from crude oil can also contain a lot of sulphur and other undesirables so is not suited for cleaning any parts of a watch unless very very dirty with old caked oil (then need to ensure you clean off all the kerosine).  It can though be used as a penetrating oil to ease tight fitted parts.  Rather than use raw kerosine use BBQ lighter liquid fuel as this is basically de-odorised, de-sulphurised and cleaned up kerosine.

I did degreased it after soaking in kerosene using solvent, but after detailed inspection, realized hairspring end was slight bent causing the balance wheel unable to stay center. I will get new one to replace.

orient 46941 movement seems no banking pins, so now is it align the balance wheel impulse pin between pallet fork?

    • although not in this case.  It was the Lugano Convention and its deficiencies that allowed a Swiss court decision in the first place.  This isnt really a Brexit issue at all.  A decision that affects both the EU and the UK should never have been heard in Switzerland. I bet the authorised service centres in the UK are pretty pleased.  It's a massive shame, though; I believe watch owners should be able to choose to have their watch serviced by whoever they trust.
    • Hi guys I think that old hippy is correct, it opens the gates for china to manufacture aftermarket spare parts. considering that they already do work on behalf of the Swiss I guess this decision gives the a little more legitimacy to tool up and I am sure they will take advantage of the situation either with or without the blessing of the Swiss watch industry  Having read about the protectionist machinations of the Swiss in the history of Europe they were the only ones to get fat at everybody else’s expense. I think the outcome could have been guessed at but ,  fair play to Cousins UK for standing up to them.  Now the question,  will everybody boycott Swiss watches and Swatch, no way they will still fill their coffers.  Me I stick with the Japanese once renowned for cheap shitty watches who came good through industrial effort and don’t for get the Russians that most dismiss as low grade crap. Wouldn’t buy a swatch product ever how about you all.? a
    • Hold the crown when in winding position, move the click away from the crown wheel, and then while holding the crown let it slowly unwind. I recollect that you must remove the automatic device bridge first, but maybe I'm wrong. You can first try without removing the automatic device bridge.
    • nevenbekriev- You nailed it with your description of me and my reaction when the clock started ticking again. I am a newbie.  I love the sound and idea of mechanical clocks but the idea of owning one and trying to keep them running has never appealed to me. My wife bought this one and an antique German wall clock.  When I looked into having someone repair them for me, the universal response was "it's really expensive to work on them, you should just replace the movement". So, I had nothing to lose, I started researching them and opened them up. The wife is happy because she hears the sound of the clocks again. But I have gone down the "accuracy" rabbit hole. In the vertical position, the balance wheel was not floating. It was sitting on the bottom of the frame. I adjusted the lower spring collet and got it floating. It easily passed the 270 degree 3 to 5 minute oscillation test. It took 8 minutes for the wheel to completely stop moving.  I put it the unit back in the movement and checked the safety pin. It does not touch the safety roller anywhere in +/-270 degrees rotation from neutral position. But the amplitude of the rotation with the spring fully wound is weak based on what you are saying. It rotates +/-90 degrees from the neutral position.  No, I did not take the movement completely apart.  That seemed way outside my skill set at the time. There is a reason I became an electrical engineer and not a mechanical engineer. I am much more comfortable with moving electrons than tiny moving metal parts. Will I do it in the long run? Anything can happen. I don't seem to be able to let it go.
