Bergeon 6016--a very useful tool

Recommended Posts

This tool has been in the watch bench and until today, I had never used it.

Now I know that it is invaluable.

Today I was fighting with a second hand.  Bending and bending until it cleared the minute hand and did not hit the crystal.  Had to remove the second hand many times.  This tool was made for the task!!

I use a longish sewing needle with the eye end cut off to leave a fork shape.  Bit of polish/cleanup to remove burrs etc (so don't damage had finish).  Pop it in a pin vice and there you go.  Bit cheaper than Bergeon !!  I use similar needles for hairspring manipulation.

The idea of this tool is the blades have a flat side and round side, slide it under whatever you want to remove,  twist the handle and the blades twist too, rising higher and detaching the part. Two downsides; one the flat side leaves a mark unless protected, the other is the "lift" is not that far. So at some point you might want to pry a little, and on driving wheels (which these were initially marketed for) you end up often with a bent or broken pivot. I don't personally know any pros who use this tool, but do know some that just call it the "pivot breaker".

Maybe I misunderstood its purpose. I thought it was for easing the second hand by bending it slightly.  i would not use it for prying off anything as it could bust a pivot as is said. Only ever used this idea once on a particularly 'stubborn' new centre second hand and it did the job without continual removal to reshape.

I've only tried this once, but it worked.  My Waltham 0s pendant watch has one of the tiniest sub-second hands I'd ever seen.  And when I had to strip it for cleaning, that tiny hand had to come off.  All I could come up with was a doubled loop of my slenderest silk thread (I do quite a bit of sewing too) with the ends threaded through a small bead.  One loop went over the long pointer-end, the other went over the butt-end, and I slid the loops up to the boss, slid the bead down the thread to hold the loops there, and gave a gentle tug on the free ends.  The hand came off neatly and without damage.  
Later on, it was a little beast to put back in place, being difficult to manipulate carefully, but coming off was a breeze.

    • HWGIKE#57 Valex FEF 190 15 jewels Swiss lever full service and repair This one was waiting for a balance staff replacement in my cabinet parts and case cleaned up with a new balance staff and a 4th wheel as the original 4th wheel had a broken pivot for the off center second hand. I never attempted a balance staff replacement before however I received a Bergeon Molfres (i was hunting it for about 2 years) and with the help of it I managed to remove the old staff and riveted the new one in. It also received a new MS, crystal and the hole for the MS arbor was also tightened. With the new MS now it has an acceptable performance meaning that the amplitude goes up to 280 fully wound, has an acceptable beat error and I have the two nice lines but only dial up, dial down is not as nice and I could not figure out as why. I have the two lines but the amplitude is dropping to around 230 and the lines are a bit hairy. Both dial up and dial down the lines just go up and down without seemingly any pattern. I cleaned the movement two times, and then a 3rd time pegged out the main plate and train bridge holes but made no change. Both the HS collet and the roller table was too lose on the new staff... I did not count how many times I took the balance cock off to sort out the HS collet, the roller table and the beat error, somebody before me also shortened the HS by pushing it out a bit and it seems every time somebody is messing with the end of the HS the protruding bit is most of the time twisted bent etc. This one was probably one of the most challenging repair and service. I might take the new MS out and clean it lubricate it as I just pushed the new one in to the barrel from the retaining ring. Plus started to re-read the theory of the escapement and how to analyse the graph on the timing machine: Greiner Chronografic Record manual. I am also thinking to put the watch on a 24 hour long run with the eTimer SW it once helped me to figure out what was wrong with a watch. There is an interesting part of the Greiner record manual talking about the pallets and the end shake of the balance and pallet staff. Maybe this is my issue? Who could that possibly identify? After a few years now I am still without a clue how could watchmakers make parts I can only see with my microscope or how could/can they carry out complicated services impossible to do.. real magic..... .... ..... before I sent this post while the pics were uploading I had an idea, i was browsing the possible outcomes on the timing machine I had one for magnetism..... so I demagnetized the movement and it is not hairy now.... two really nice lines 0.2 ms beat error still a bit wavy, but a lot lot better..... argh....  
    • Hi there, welcome here.  
    • yes the advertising revenue should generate money. The question is how much money? Then as far as the cost of the website goes that's relatively easy to determine? all you would have to do to grasp costs and profitability would be to go to the link below and you can actually get a website for free try it out for free I believe you get no advertising initially. They also talk about that they'll help you out they have marketing tools and some sort of paid subscription or something. So I guess were shopping for a whatever just ask them what would a maybe could use this one as an example in other words it's going to look basically identical to this is going to have advertising a paid subscriptions what's it going to cost? After all they want to sell or give us a message board like this they should bill answer the questions as they're the people who did the software for this. Yes they really said you can have a free discussion group at least to start. https://invisioncommunity.com/ I was curious about the monthly supporter thing where exactly do we find that on this message board? A quick search I'm not finding it so obviously I'm not looking in the right place?
    • Help me out here, but with all the advertising on this site (which I don't mind) wouldn't it pay for itself or even make money for the owner ???
