NEED HELP - Bergeon 5700-BP


Apocalypto

Recommended Posts

Hi everyone I am interested to buy Bergeon 5700-BP.

But before I buy it I need to see if someone can answer my questions, as I tried to contact bergeon itself but no response...

Anyone have it or can help me if this type of tool opens the most tightened back pressure cases and that can reach the back lip that sometimes its in the corner of the bezel and that it can open those that don't have back lip (Like Tissot / Longinges etc..)

I appreciate if someone can give me some advice before I buy it please.

Thanks,

Steven

I have one albeit the Chinese version. It will open any screw back watch case. Mine came with a set of milled edge adaptors for opening Rolex cases. I use it mainly for opening really tight cases because it has a locking wheel for maintaining downwards pressure. Especially useful when the gasket has degraded to a glue like substance. It obviates the risk of your watch looking like someone has opened the back with a chisel. I have mainly sixties and seventies Tissots on which it works well (except of course the Seastar Seven) The only down side is that its rather large being nearly 1 foot in height (30 cm) and the wheel at the top is like the steeing wheel from a pedal car being 6 inches in diameter (15cm) How it compares with the Bergeon version I'm not sure but what the hell its for taking case backs off. I wasnt about to remortgage for the sake of Bergeon. If you have a good set of basic tools then go for it.

Thanks for your help but 5700-BP is a different tool its not like 5700-Z. The one I am talking about is to open the pressure back cases (snap on) not screw back cases.

I think few people have bought this tool...

I don’t think so. You need to pry these open.

The problem with prying manually is that as soon the tool slips - and on tight cases it does, you've got a scratch. That isn't acceptable.
Some members here got an affordable Chinese tool and I think I'll get one too. There is also another hinged type, but it's all plastic and I would not recommend it.

I have not scratched one yet, but I can see your point. Will the Subject tool work to remove a snap on case?

Yes, this will remove a snap back case. One of the chisel points is extremely fine. If you should ever have a case that is too tight for the fine point to enter, just tap a single edge razor blade into the slit and that will open it enough. The tightest watch I've ever opened was a Bulova dress watch and this tool opened it with ease. It's also good for removing bezels.

I didn’t think I needed to buy yet one more tool, however......

In the grand scheme of things, a tool is less expensive than ruining a good watch. Mine is a Horotec knock off produced by a Pacific rim country. The center post is fully adjustable as it is spring loaded so you can easily move it to the correct position. I purchased mine on evil bay for about $40 USD.

I guess you mean Chinese? Is it the same in picture? Nothing wrong with posting links here as long is not blatant advertising.

    • So here is the new base (v 2.1), I made it so that the base will fit over and swallow the stump of the hand pusher tool (or at least my clone of the tool), I also reduced the OD of the bottom skirt a little as it looked/felt a little large, here are a few pictures and the fake .pdf file which you need to convert to .zip once downloaded.   The cut-out seen on the below image on the bottom of the base should swallow the OD (40 mm, +0.1 mm tolerance) of the stump and the height of the stump 9.5mm (measured to 9.1mm, but rounded to 9.5mm) - let me know if this works for your tool.   Note, I think you may need to print supports for the new internal shelf created? Here is the fake .pdf for just the FreeCAD base file and 3mf files Modular Movement Holder.pdf Here is the fake pdf for complete set of the new base and ring FreeCAD/3mf files: Modular Movement Holder base and ring v 2.1.pdf
    • Hi Frank, you have dived headlong into the deep end. Hairspring work has to be the scariest thing a newbie has to tackle. Your hairspring appears to be bent and just putting it back into the regulator would not allow the balance to work properly. It might start oscillating but the performance would not be good. The proper thing to do is to unstud the hairspring, remove the hairspring from the balance, reinstall the hairspring on the stud carrier, reshape the endcurve and centre the collet to the balance jewel hole. This challenge would either make you or break you. Hope that you will be able to fix your watch. Welcome to the world of watchmaking.  Watch this video. It think it'll give you an idea of the task ahead. From your 1st photo, I think you have a etachron type stud. Let me see if I can find a video on how to remove it from the arm.
    • Have read of the Tech Sheet attached on the balance section page 12. It may be bent but until you reposition it back in the regulator pins you'll never know. Cheers CJ 4R35B_4R36A.pdf
    • Aloha All, My Seiko 4R35B movement stopped working today. Upon closer inspection, it looks like the balance spring came out of the regulator pin. This is my first time working on a balance. Any advice on how to get this spring repositioned (back to normal)? I'm pretty sure that while adjusting the beat error on this movement, I must have turned the stud (I didn't even know they turned), and the spring eventually fell out.  Will the spring go back to even spacing when it's back in the pin, or does it look bent? Thanks, Frank  
    • Good job, that band matches the watch perfectly.
