Damn this is is amazing, price not so much, but it sure is very well made.

Anyone else have one, and if so, do you know the best base plate for off-centre pusher work, i.e. chronographs, ETA 7750/53?  I have a new movement holder for these two movements on back order, but unsure of the base plate I need.

Hi Micky, I have a couple of hand presses.  The old one is a twin station version of the press you have and is built like a brick sh** house; the second single station press is more lightweight.

Both of these give a huge amount of feel when fitting hands, but I have made adjustments to the single stage one to give great sensitivity and feel. The anvil fitted to this press is made of high density polythene and prevents the movement being marked.

The small anvil, Bergeon 5409 is a great addition.  It has a centre pin that rises to support the bottom pinion when pressing hands on.  This eliminates the possibility of moving the bottom jewel during the process.  It is not suitable for all movements though.

Cheers for that @Geo   I will certainly look into that, but for 28XX ETA movements I have this slick movement holder, and found it fits the base of this Bergeon hand press perfectly.  Its the base plate for 7750, and 7753 movements I wish to find, a base which allows for off centre pressing of the small chronograph hands.

@sstakoff The timegrapher is amazing, so many settings, and custom settings, memory, print out functionality, and readout options, loving it, esp[ecially with the auto mic, I can let it run a custom test of all six positions whilst I carry on with other work.

@clockboy I have both of the Horotec hand pressed, the singular type, and the trio model, I found the trio press tool a waste of month if I'm honest as the two pillars obstruct many movement holders for the two end pushers to be used.

Thank you. Appreciate the review.

Just read the paperwork that came with the 8935 press, and it shows an intermediate plate for offset driving.  Typical of me to not read the instructions, I have the part number too, so will order that next.

This is the movement holder I have on back order with Boley, and right now, I am unsure if it will be useable with this press, if not, a good reason to look for a singular like Geo's?

Very nice Micky, I think you might have to have have a custom base unit made.

I think you could well be right, I have a lathe, but I haven't got round to restoring it yet, let alone buy any tools to get it up and operational.

So that is how it works? Seen it but never understood what it was for? Thanks  @Geo

You can use the movement holder such as for the 7750 with the horotec but it is not as slick as the Boley or Bergeon but it does work.

Thats what I'm thinking in the short term, and would like to keep my Horotec presses just in case, I will let you know how I get on with the offset intermediate plate.

I've never understood this. What is the bottom pinion?

@jdm The bottom pinion, and jewel are the rear end of the seconds wheel, if this isn't supported during the refitting of hands, you can damage that pinion/gear/jewel, thats why there is a centre post in movement holders for specific movements.

As you can see from the 7750/7753 movement holder I posted above, this has several posts, each adjustable to comfort/protect their respective jewel/pivot/gear whilst refitting the hands.

I see. On Seiko and I guess many others there are various parts in between which make that impossible so I guess it's not even needed.

On Seiko chronographs such as the 6139 there's a tool which supports the jewels the same as the above tools. You fit the dial and hands before fitting the auto winding bridge. Here's a picture of the tool stolen from the internet -

Hi

I know it's not what you were looking for but did you know Bergeon sell an offset stake attachment for small seconds/chronograph hands, 6012-SD? I imagine that would do the job on any of their hand setting tools, but who knows what it would cost!

I did, there's two, and I have ordered them both from cousins, not cheap at £60 each.

Do you mean the plates? That's not what I referred to - Cousins don't sell the part number I mentioned as far as I can see. It fits on the end of one of the stakes and looks like it is adjustable. Was originally for a different press but I imagine it would fit.

I'm not sure whether it's discontinued, or just an older model as the construction is different. Anyway I would think all the fittings are the same size. The description for your model actually lists 6012-SD as an accessory, so I assume it will be correct for the 8935, there is no newer version of this piece.

    • Hello everybody, sorry for the late reply. Thank you all so much for your help and your tips. I got lucky and found a replacement wheel bridge for cheap which actually ended up being in decent condition. I decided not to do anything about the mainspring barrel pivot since I didn't have the right tools and the barrel didn't have much endshake anyhow. I am happy to report that the watch now runs great, I have regulated it to about +-10/s day which is fine by my standards. The timegrapher result looks decent as well, although beat error is around 0.6ms which could be better I suppose. Amplitude reaches over 230 quite consistently which I'm happy with also. My lighter fluid has also been replaced by balance spring cleaning solution and now the springs don't stick to themselves anymore - who would have thought. I'm super happy with this watch, it might not be worth a whole lot but it's awesome that I could restore it and it makes me wear it with pride. To me it's a genuinely good lucking watch, it'll be my daily driver for a while. Thanks again to everybody for their input! I couldn't have done the repair without your help.   Here are some images for those interested, the bracelet isn't original but I don't really mind:    
    • Balance-hairspring system is oscillator with big Q-factor. When all in the movement is OK, the rate (frequency) is verry close to the own resonant frequency of the balance-hairspring. But in some cases, the movement (with foult) will force the resonator to work on pritty different frequency, sometimes faster, and sometimes slower. When this happens, the amplitude is always weak. So, the first thing to ask is what is the amplitude. If it is more than 180 and the hairspring doesn't touch itself and anything else, then for sure it is 'short'. If the amplitude is weak, then the first thing to do is to understand why and rectify the problem. At this time no point to check timekeeping. But, if one doubts that the hairspring is not correct, then He needs to calcullate the rate of the movement, then to 'vibrate' the balance-hairspring out of the movement and to measure the free oscillations frequency (period) with timer in order to ensure that they comply with the rate. If we have pictures, then it will be easier to tell something about that wheel.
    • So much work has gone into this! Thanks again @Jon. I will go back and check my adjustments from last weekend. A few questions for you, if you don't mind. In the reset position, I can understand the problem if the gap between the hammer and the minute counter heart is too big (slide 77) but what is bad about both hammers being in contact with the cams (slide 76)? I read somewhere that Landeron recommended grease on the runner cam, but the minute counter heart should be dry. Is that so, and why? How many tads in a ligne?
