Bergeon 7825 Spring Bar Tweezer - HT7825

Product Information

Specially designed glass bottle for Epilame. For use with Moebius-Fixodrop No 8940, 8941, 8950, 8951. Comes with bottle, cap, and basket. When you remove spring bars with a pen-shaped spring bar tool, you have nothing to compress the spring bar with, which means you have to pull it out instead via the strap or bracelet. This can cause the spring bar to fly across the room or scratch/create dents on the lugs as the pressure from the spring bar is pushed against the lugs as it is being removed. The fact that you can prevent scratches on your watch completely is the main benefit of this tool. If you change straps regularly on your watch with the wrong tools, it can cause your lugs to acquire a lot of scratches and dents over time. This is obviously something you want to avoid. This is why this tool, according to us, is well worth the investment. As you say, for me right now it would be clearly best to go 6825. It's unlikely that I would acquire another Rolex (though I do have a soft spot for the Explorer 216570) so I feel I can safely ignore the 7825. I went for the one with the finer forks. I have used the FF on a 16570 Explorer II, but the tips were still too wide to use on a 16200 DateJust on Jubilee bracelet. 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.

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.

Using the Bergeon 7825 spring bar tool, removing spring bars will be a breeze. Plus, you will minimize the risk of slipping or scratching your watch.

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. by Amor Vincit Omnia» Mon Apr 03, 2023 6:02 pm» in Straps 9 Replies 385 Views Last post by Bahnstormer_vRS 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. 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. Progression 0.025 mm. Bergeon reference #30350-D-02.

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.

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. I have finally managed to source a bracelet for my Mk2 Trident so it's time to seriously update my bracelet toolkit. 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.

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. I have the Bergeon 6767 tool and successfully use it to remove the bracelet on my 45.5 PO (cal. 2500C). I find it the perfect tool to remove straps or bracelets from all my watches, some just need a bit more dexterity than others. Here's the exact answer I was looking for. a big thank you to you for having been kind enough to reassure the anxious old man that I am.

Works perfect. Fits nicely and easy to work. Takes out a lot frustration when fitting the bracelet to the watch head. I see what you mean about the 7825 being designed specifically for Rolex. I looked deeper and the tips are just 1mm, while the FFs for the 6825 specify 1.1. That 16200 must have been a nightmare!there must be, on this forum, people who have speedmaster, want to change their bracelets themselves & use the right tool.
