Bergeon 5700-Z and Horotec 07.130 Purchase?

Recommended Posts

Hi guys! I've been looking into upgrading some of my most used tools, and arguably, one of the most important tools I currently own. 

I've been reluctant to upgrade my caseback opener and crystal press to the upgraded, Bergeon 5700-Z and Horotec 07.130, due to their costs.

Currently, I'm using a chinese copy of the Bergeon 5700-Z, which has served me well, but the tolerances are not perfect. The bits that attach onto the bit holder do not sit parallel onto the casebacks I remove ( one sits slightly higher than the other ), which causes a large risk of slipping and scratching casebacks. In addition, the bit holder does not adjust evenly such that the bits don't move equidistantly from their respective sides, which makes it difficult to center the bits perfectly onto casebacks. 

As for the crystal press, I'm also using a chinese copy of what resembles the Horotec 07.130, except the lower threads don't sit on the actual base of the tool but are slightly elevated onto an intermediate plate. This leaves a small gap between the actual bottom dye and the base of the press. I've noticed that when applying a lot of pressure onto the tool when setting crystals, the intermediate base where the bottom dye rests on bends slightly down due to the applied force. The crystals seem to be going in very evenly so this has not been an issue, however, I like how the Horotec 07.130 has their dyes sitting on the actual base of the tool so that the bottom and type dye will always be parallel upon applying force downwards. 

 

This leaves me to ask, can anyone who owns the Bergeon 5700-Z and Horotec 07.130 provide their opinions about either tool? It is a rather large investment for someone who does not work on watches full time, but works on enough to consider it a part-time job. 

 

* Just a side question regarding the type of dyes to purchase for the Horotec 07.130*

I install both domed and flat crystals, but I'm unsure if the "Set of 12 Delrin Thread-on Dies for Fitting Very Domed Crystals" by horotec would be the best choice for my application.

 

Thank you everyone.

Hello,

I use the Bergeon 5700-Z... and I notice some extra work with the standard set. You always have to remove the strap or bracelet to fix the watch in the basic holder. Think they have a optional set so this will help the problem.

This problem is not present with the standard Horotec tool because of the different standard base and the Horotec is cheaper.

I just received the same Chinese crystal press you have,  and I had some of the same concerns about rigidity as you. Glad to hear that it hasn't been a significant issue.  I suppose if it does become a problem, it will be time to come up with a metal block to slip under the support.

Same, for a reasonable price: https://www.aliexpress.com/item/2029153808.html

BTW, my Chinese 5700 doesn't any of the issues described by the OP, and works perfectly. However, the casting isn't perfect, and the some of the bits sent were duplicated. I remedied that easily on the lathe,

I think that can be caused only by the square pieces that hold the bits to be different height, and/or the bits themselves to not be accurate. It should be correctable without any special tool.

Check that the square parts mentioned above are assembled correctly, that is they are inserted on the same turn of the threaded bar. Also, avoid tightening their knobs, so they can align better.

    • Welcome to the forum Jeff, enjoy.
    • No, the Peseux 7040 is doing very well as far as the rate (and amplitude) is concerned. The maximum delta measured was 20 seconds between fully wound, crown down (+8 s/d) and fully wound minus 24 hours, crown up (-12 s/d). Compare that to the ETA 2763 having a delta of over 80 seconds. What I was trying to convey was that I observed that the much higher amplitude of the Peseux movement during a 12-minute measuring period could momentarily fluctuate by 30° just like the much lower amplitude on the ETA 2763. I haven't studied the History graph on @praezis PCTM software for any other than these two movements but I wouldn't be surprised to learn that these fluctuations in amplitude during a 12-minute measuring period are the rule rather than the exception for all typical non-high-end-chronometer movements.
    • I'm presently using a cheap supermarket ultrasonic cleaner, with L&R #111 cleaner and #3 rinse solutions. I cut a bit off the bottom of an appropriate size plastic sports drink bottle, which is a perfect fit around the mesh basket I use (~65mm diameter). That allows me to use mostly water in the machine tub and cleaner or rinse only in the small plastic container. I keep the solutions that are still fit for use in small glass jam jars. I use the cleaner then two rinses, then the mesh basket balances on my bathroom radiator (once it stops dripping) to dry the parts with moderate warmth. Prior to that I tried just lighter fluid (eg. generic zippo fluid) and just soaking / swirling parts in the glass jars, but the movements did not run at all well afterwards, they were still acting gummed up. The proper solutions make a world of difference & the watches now work as they should!    
    • Have to agree with you. Will not do another. Did not enjoy the time spent. However, it was worth it to know that I understood how to disassemble, look for defects, repair and then assemble. Timegrapher? No facility to alter anything other than the stud. Everything is metal to metal.
    • Couple of things H. There surely seems to be a reoccurring fluctuation pattern  of somewhere around every 5 minutes. More noticable with your crown left trace having a large peak gradually reducing to 2 small peaks and troughs then back up to another large peak. Nev posted a download link to a book by Harold Kelly not so long back that i started to read while i was away. There was a good section on wheel and pinion ratios, rotation periods of wheels of different beat frequencies that's worth a read. Then something that bugs me comparing the amplitude and timing rate changes with your dial up trace which i chose to avoid wheel imbalances . The amplitude fluctuates by an extreme of 30 ° and the rate fluctuates by an extreme of 21 seconds as per your reading. In normal circumstances a movement dropping its power over the course of the mainspring unwinding, a hairspring acting isochronical will maintain its rate almost to the end of the power reserve. Similarly power wound into a movement increasing its amplitude from 265° to 295° a hairspring again acting isochronical will again maintain its rate aside from a brief few moments until it settles into it's rate. From that it seems to me that because the amplitude difference isn't big enough to affect a rate change then the amplitude fluctuation cause is not coming from anywhere but from the balance. So its whatever is causing the rate to change increase and decrease within the balance is also slowing and speeding up the hairspring swings. I'm not quite sure if I've just gone around in circles with that, it made sense to me when i started  😅 We did have a discussion a while back when i asked if rate could come from that point as well as from the regulator pins. This area can be electro stiffened in high grade hs i remember was the answer. I remember that over Ross's issue with balance endshake.
