Brand New! Just found this Bergeon Stem Cutter, unfortunately like so many watch tools this item is no longer available. I have been watching this topic with interest as the shared experiences are very helpful, thank you. Oh: there's a really nice read on hairsprings, that I have always thought highly of; "Practical Balance and Hair-spring Work", Walter J Kleinlein, 1925. As I recall, he was at Waltham's factory in Massachusetts, and pretty-much looked upon as a Final Authority (!) in such matters. I met one of his pupils, Andy Taber ( RIP ), who operated a nice shop in Bangor, Maine. Andy attended Waltham's School after he Served in the USA Army in WWll, and mentioned that Walter would 'pass' a piece of his student's work, when it was...CORRECT. PERIOD. Most watches use spring bars to keep the bracelet or strap in place and to remove the spring bars, you need a good tool. But with that said, not all spring bar tools are created equal. Problem with tips breaking may have to do with spring tension. Some spring bars have weak springs, but if you run into one with a strong spring. Using tweezers is going to be a little more difficult. Plus keeping those small tips centered.

Nik IIRC when I bought the 6825 there were two types of fork: F or the finer FF. The indication from stuff that I read on forums seemed to be FF for Rolex/Tudor, with F for Omega and others. There’s a reason the professional watch world uses Bergeon - they are simply the best tools for the job. Enough said!

Comforting to hear that the 6825 can handle CW bracelets easily, they also managed one of my Seikos but it was not as easy as I thought. Probably not a fair test though as the tips were hopeless and I ended up completing the job with the trusty 6767. Most spring bar tools are ” pen-shaped”, with which you remove one side of the spring bar at a time. The 7825 from Bergeon is a bit different, however, as it is made as a tweezer with which you tweeze both sides of the spring bar simultaneously. The benefit of this is that you can more easily grip both sides of the spring bar and carefully ”lift” out the spring bar, which ultimately prevents scratches on the lugs of the watch. Similar to the OP, I have the Bergeon 6767 tool with the fine 1.2mm tip and the wider 3mm tip, and whilst it has worked fine with all watches in my small collection, I do fancy trying the pliers/tweezers for easier changes and less risk of scratching the case lugs during the process. I will say that it’s worth it when really you do need it... it can really keep the frustration levels down. But for everything else, the 6767 is much easier to use. Spring bar fitting tweezers with extra fine tips measuring at 1.00 mm diameter. This tool is great for bracelets with small spring bar openings. Allows to take off the bracelet from the watchcase without removing the clasp.

I have the N° : 6767-F and i would like to know if it is ok before i go to work on my 3861 speedmaster I have a 6825 just had to replace original tips with fine tips. Work great on my Rolex spring bars. The 7825 WILL work on Omega spring bars, but the fit is suboptimal - it will slip off much, much easier than it will off a Rolex spring bar, and this (combined with the single flange design of the Omega spring bar) really negates the advantage and secure grip the 7825 offers on a Rolex spring bar. Works perfect. Fits nicely and easy to work. Takes out a lot frustration when fitting the bracelet to the watch head.Yes, the tool is expensive. It can feel tempting to opt for a cheaper alternative, but you really do get what you pay for here. It is the tool that is used by professional watchmakers and your watch deserves only the best. A wonderful tool that sure looks good. Allows the pivots to be straightened without breaking due to a control device as well as a screw fitted with a stop. 41 Jewelled holes diam. 0.07 - 0.15 mm.

I've read threads here that the Bergeon 7825 is ideal for Rolex and Tudor spring bars / bracelets. And I've read that the 7825 can be used for an Omega bracelet, but the spring bars Omega uses are different than Rolex / Tudor and the 7825 tool therefore does not work as well. The original blades made with softer metal than the stainless steel blades. Some prefer to used the original blades with their Stainless Steel Screwdrivers when working with older watches that do not have stainless steel screw.Thanks for that, another option at a better price than Bergeon, though it looks like it could not handle a Seiko fat style (tips are too narrow). A pity they don't also make a 1.3mm size so that one could interchange with the 1mm. Maybe a future? I would need to pay EU VAT etc on import from Esslinger so it is not a low cost option, but at least the tips are fair price, unlike Bergeon! Best for what you are looking for is probably Bergeon tips for the 6825 clone you have. I have found that when I used the 6825 with CW bracelets it was easy. I have managed to use them without separating the bracelet, but quite difficult. I have both the Bergeon 6767 and the Bergeon 6825. To be honest I use the 6767 possibly 99% of the time, but there is always the odd occasion where the 6825 comes into its own. Whether it’s worth it or not is entirely another matter. Those tweezers are the best. You should tape the lugs regardless of the tool you use. I use painters tape. Perfect tool for removal of Rolex bracelets without scratches. Not suitable for my Omegas though, as the spring bar design is different. Perfect tool for removal of Rolex bracelets without scratches.

I too use double shoulder spring bars or Swiss type from Cousins which give the same ease of access, see this thread: viewtopic.php?f=53&t=50289 if you have not already. I ended up getting the 7825 because the width of the tips on the 6825 were too wide for a DateJust, but ok for other 5 digit models and Tudor. Looks to me that the 7825 were definitely designed for Rolex/Tudor and the style of both springbar and gap they use. These two are very competitively priced and not sure which to get between them... any pointers would be greatly appreciated. I have the tools you mentioned above - and a Rolex Sea-Dweller 116600 - in addition to my Omegas. The 7825 works superbly on the Rolex design because the spring bars for Rolex are double-flanged. This means there is a second flange on each end, so the 7825 has a very secure groove into which it fits to compress and expand a spring bar during installation and removal. The diameter of the spring bar is also slightly different from the omega spring bars. many thanks for that, it confirms my research but I do not have the practical experience, so valuable insight. The 7825s look like the ideal design, but not there (yet) for my immediate needs and I don't like the fact that any replacement tips are ludicrously expensive - presumably Bergeon have caught on to cheapo copies needing properly manufactured tips.

I just don’t how to change the blades because they are supposedly changeable. Works perfect. Fits nicely and easy to work. Takes out a lot frustration when fitting the bracelet to the watch head.
