This is a great tool for tightening pipe hands on vintage watches and especially the centre seconds hands on 7750 chrono and reshape centre seconds hands on seiko 6138 and 6319 movements so you can repush hands on back at zero. Even short pipe. Just pick a collet, place it into the tightener and turn screw slowly, rotate hand and repeat. And presto you can now push tight hands back on. From .4mm to 2.6mm

I do use a lathe chuck for the same purpose. But it would be nice to have one of those pipe tighteners as they do have advantages - the large surface plate lets you ensure the hand (or winding crown) remain flat as they can become distorted when tightening, and the chucks supplied also have flush ends rather than being domed. 
It may also have a finer thread for tightening which may give better control. 
Still too pricey for me though.

I just bought one of these, 20 something years in as a professional, used either the lathe and collets or pinvices that take Schaublin P4.5 collets (have a bunch) all this time, but given the number of chronos I do figured the auction price will pay for itself in a year then I get 2 decades of free use till I retire. Then back on Ebay. I'll start it at 1 buck in 2040, haha.

amazing tool...but a bit pricey for me

Hi Mr Watchtime yes very pricey. I should go to the boutique watch stores here in Australia and see what they have done with their seconds hands. Pick them up and retighten them and sell them back to them. Maybe pay for itself. ?

A professional tool but probably a bit out of the range of the hobbyist who w ould  not do enough to justify the cost,  but as a tool junkie  Nice.

Hi Mr watchweasol your correct, but it is very nice tool and extremely handy for vintage watch resto, I like to make sure original hands are tight. It's also great to sit back and look at it. (that's the tool junkie bit) ?

For completness, the high price mentioned above is currently GBP 505 before VAT (where due). Consider spending the same or less for some precision lathe collets and chuck. 

Hi Mr jdm, I got mine for nearly 200 pounds cheaper than that, but yes you could use collets in lathe. But I guess it's like everything, you pay for convenience. ?

Hi Mr rodabod, for even more control there is an allan key that fits into the middle of the tightening knob for very small controlled movement

Hi Mr nickelsilver I do believe it will pay for itself.

Hi Mr oldhippy sometimes I have to bite the bullet, and they obviously know it. But nobody else makes a tool like it. Anyway if you like I can rent it to you ?

Ha Ha Ha, thanks but no thanks I retired from Watch Clock/making back in the second half of the 80's due to poor health.

But still your contribution to the industry lives on and on, good stuff. But still you don't have to use it, you can just look at it.

I use this for chronograph hands:

hands_press2.jpg.c7c84e025c98baf723c21daadc6b8a95.jpg

Made from a small pinvice, it works sensitive, fast, repeatable and takes least room in the drawer ?

With the Bergeon tool I am concerned if the procedure will be durable. It makes a small constriction on the tube and does not narrow the whole tube - what I learn from its description and drawing.

Hi there Praezis, that's a handy second hands tool you have, as you say doesn't take up much room. The bergeon tool is made for tightening the whole pipe of hands and you can also tighten crown pipes and case tubes. Here is a photo of inside the smallest collet 0.40mm. The tube section where the hand fits is about 4mm long

Hi Graziano,
did they change the collets design?

I was referring to this info from my Bergeon catalog:

Frank

Hi Frank, looks like they have changes the design, this tool is the newest version and it will tighten the length of the pipe. Especially good for Seiko 6138 chronograph, to be able to use the same centre seconds hand. You need to round and tighten the tube to place back at zero. Also flyback chronograph, and any other hand. Cheers Frank

      Thanks Dell. I thought about silver soldering. Have never done it but would like to give it a go. Do you think to put flux on the butted joint then run the solder in or to maybe brace it with a piece of scrap spring steel?

      Never and others. Yes, like you I do spend a fair amount of time reading the contents of this forum. I find it better that any other. Clear, lucid, no Prima Donas, and most of all an easy access without adverts. All thanks to Mark. God bless you mate. You give so much to many of us. What if? No Mark? Hypothetically. A forum. I did run a forum for a few years. Really enjoyed it, but became so engrossed that it did affect my health. I gave to to others to run. Not been back. It was very successful and rivalled a number of large paying sites. No adverts, no others but me. I did ask and listen to members comments and it worked well.    Costs Having a domain name, £10 annually.  Register the site with a forum company, free. Build the site using the forum company guide lines, free. It looked and ran almost the same a Mark's. All the same facilities. The cost was only £5 per month, but counted visits (views). If I recall, it was that price for 5,000 views. Each extra 5,000 views increased the price by £2 per month. Success was my own personal undoing. From £5 per month initially, it rose to £60 a month and looked like increasing. This was 10 years ago. I could not afford that, and asked it anyone would like to take over and someone did. I would assume that this is the price that Mark is funding for us all. His return is our continued comments on the internet about his course, and the fact that many of the big names on YouTube mention him as their Tutor. Those of us who have done, and are still using, his course, benefit. In comparison to other courses, I can't believe how cheap it is, and the value is exceptional. It is the structure that gives the value. Long may Mark reign. Ross

      Help please.

      Hi all, total newbie to watchmaking and I've had a bit of a mishap. Just completing level 2 and was doing ok, but I was just on the last part of the reassembly of my ST3620 when the balance end stone shot across the room, just as I was trying to see if I had put the correct amount of oil between it and the balance end, aarrrgh! Been on my hands and knees combing the carpet for 20mins looking for it but to no avail. Does anybody know where I can get a replacement from and what to look for please?? Thanks.

      Get someone local to tig it ,very easy fix and should only take a few minutes so probably wouldn’t cost much ,or failing that get it very clean and silver solder it. Dell

      Movement inserted from crytal side

      By Zedster · Posted

      Hi, The winding pin is not split, well that's how it was when I obtained the watch. The movement is front-loaded and here's a picture of where the case screws are fitted. The face picture is before I dismantled it. Quick update.  I've always had a nylon ring sitting in the parts try that I wasn't sure where it went and left it to the last thing as I know it must be part of the case assembly. Anyway, looking at the picture in my last post you can see, just under the winding stem, a white-looking object, this is the nylon ring 🤭 So, I had to remove the dial again and replace the ring. Once this was all back together I placed the movement in the case and realized my initial problem maybe is not a problem as it looks like I can screw the movement back in the case and then place the hands as the dial is nearly flush with the outside of the case anyway so I'll be able to check for alignment. if all is good then just fit the crystal and bezel 🤔 I can't think of any issues with this approach but please comment if you think I've not thought of something. Another lesson learned as well. Take more pictures not just of the movement parts and location 😅
