Hello, 👋

I've gathered information about automatic main spring barrel walls and i know what lube is needed for them (8217, 9500) braking grease however I currently only have these: Moebius 9415, 9010, D5 and Molykote Dx paste the basic oils and grease for beginner now is it really necessary to have the other braking grease at the moment as i dont know if i can sell another kidney for more grease 😄 is it maybe viable to use any of the ones i currently have ?

Thanks !

Unfortunatly the OP has financial constraints and is/was looking to make use of what he has not shelling out for another expensive product.       Kulber P125 was discussed on the nawcc site, and Henry B Freid used graphite / oil paste , so there are vairied alteratives on the market.

Are you sure? Kluber is graphite filled and a dedicated breaking grease. DX is PTFE filled and not adverticed as breaking grease.

I am also confused here. the Kluber is a black really sticky substance that if you use too much it has too much breaking and is very bad.The DX is actually rated as a lubricant for very high pressure applications and I wouldn't consider it a breaking grease at all. So I'm a bit confused for the same reason.

I really wish it was this simple we would all be happy to have one bottle of oil for everything it would make things so much nicer unfortunately it doesn't work that way I have a interesting video for you

the problem with the video is it conflicts with the theme of this discussion, The wrong lubricant will lead to the barrel destruction. The wrong lubricant if the mainspring doesn't slip leads to timing issues which probably be acceptable on a cost basis in other words does the watch have to really keep time versus how many kidneys you have to donate. You know in some countries you wouldn't have to use your kidney just steal one from somebody else I've heard that's a thing.

the bad of the video is it explains consequences of the wrong lubricant. If your mainspring doesn't slip as you can see in the video you will have timing issues. If you go the other direction something that's too slippery the mainspring may not have enough power at all to run the watch. probably if you keep it on your wrist you'll be okay just depends on how easily it slips

Then at about three minutes we get the interesting aspect. not only do you have to have the right lubricant but how it's applied is important. For instance in the video if this was Kluber and you apply as much as he's doing I don't think the mainspring would slip at all well it was slept but it be really really hard.

Although Rolex and brietling stopped using it because it dirtied the cleaning fluid

the Rolex lubricant is called TEPA the reference I'm looking at indicates it's not of the same color as the DX which makes me suspect it's not the same thing. but breaking grease does have to have a grease characteristic to keep the barrel wall from disintegrating. Which makes me suspect that probably uses Teflon so it is a breaking grease with a Teflon lubricant.

learning watch repair can be interesting thing that requires a lot of practice. But maybe it also requires some experimentation and this is a multiple-choice question so I'm will vote for the DX as the others are totally unsuitable as they would have zero breaking effect at all. So let's try the DX and see what happens.

I have never considered Moly to be a braking grease, nor can I remember ever having seen it being recommended for this application on any sheet including Rolex - or at least I have most of the Rolex service sheets and can't remember seeing it. Kluber 125 is my go-to now but sparingly applied, I've seen it really being piled on in certain Instagram posts in the past 😟.

To the OP - my two cents: I recommend grabbing some Kluber or 8217 if you're going to be working on any number of automatic movements - it will definitely improve performance and give you peace of mind that you have done a good job.

      Epilame / Fixodrop

      By Klassiker · Posted

      OK, let me try and expand on why I think this is right (but maybe misleading at the same time). Wikipedia has a good explanation of surface tension, which is where I got most of the ideas below. The cohesion of the liquid molecules binds them together into the most compact form possible. If there are no external forces acting, this is a sphere. Surface tension is the combined effect of the cohesion between molecules on the surface with others on the surface, as well as the cohesion to molecules just under the surface, causing contraction and the formation of a denser "skin". The way a droplet of a liquid forms on a solid surface is determined by the strength of this cohesive force relative to the adhesive force between the liquid molecules and the surface material. If cohesion >> adhesion, you get a droplet. If cohesion is similar to adhesion, the liquid tends to spread out on the surface and creep away from its original location. Oil doesn't have the same high surface tension that water does, so it is not going to form a really rounded droplet on any surface in the way that water will "bead" on wax. This is where my earlier statement is misleading, but it is still exactly the same principles at work. Drops of oil on an epilamed surface are not going to run off in all directions at the lightest provocation. What the epilame does, I think, is reduce the adhesive force to the surface somewhat, making the weak cohesive force of the oil molecules more effective. The result is less tendency of the oil to spread out and creep, and more tendency to stick together as a cohesive mass. I don't think epilame has any effect on surface tension. That is a property of the liquid and is determined solely by the cohesive forces between the liquid molecules. I also don't think the epilame makes the liquid "stick" to where it is applied. The oil adheres ("sticks") more strongly to a non-treated surface than to a surface treated with epilame. This is why the epilame needs to be removed from the contact surfaces by running dry for a short period. The oil then sticks more readily to the local contact surfaces, where the epilame layer is worn away, than to the surrounding area. The oil sticks together, and is thereby anchored in place as a single body. Interestingly, reducing the adhesion of the oil to the solid surfaces will also reduce capillary action, which is what we rely on if we don't use epilame. Another reason to make sure the epilame is worn away from the spot you want the oil to stay put.

      Installing new balance complete in a Unitas movement

      Look up index vs free sprung balances.  The screws are for timing.

      I was considering just building a watch from scratch, I've heard the nh35 movements have a lot of case and dial choices and apparently they run poorly when you buy them new so a good service is required. But honestly building a watch like that doesn't interest me. I love fixing things. There's nothing more satisfying to me than taking something broken and making it work again. Plus watches are cool 😎 and easier to store than a car engine! I only had one engine in the dining room and my wife complained. Hopefully the watches will go unnoticed.

      Hi all, My "practice" watch has a worn our balance pivot, so I ordered a balance complete. Pieces nr 4871 for Unitas 6310. It's probably no big deal, but my original balance wheel has plenty of screws or similar protruding all around, while the new one I got doesn't. What's the purpose of these thingies? I haven't installed it yet, maybe next week. Thanks

      What tools does ebay have to offer this week.

      By VWatchie · Posted

      For those of you who are looking for a Seitz jewel gauge, I just want to make you aware that there may be a good opportunity right now at Tradera.com (Swedish eBay). The site has significantly fewer visitors than eBay and I have made several fantastic deals there. 1500 SEK corresponds to approx. £110/€128/$137 https://www.tradera.com/item/1922/631487681/seitz-urmakarverktyg-matare Just to make sure, I'm not associated with this listing in any way!
