what do you use on your pallet stones, epilame and...?

Just realised my previous reply could be misunderstood.

I epilame treat the pallet stones (not the entire fork) but I do not let it run dry before applying the Moebius 9415.

George Daniels is likely turning in his grave over the use of epilame, oiling, and the use of the Swiss lever escapement.

Moebius 9415. Hope that answers your question.

Just browsed it through and found a reference to "Working Instructions", but I would need a login for that and I guess that won't happen without being accredited. I'm super curious to know if Omega recommends the "rub of epilame method" on the pallet stones before applying the oil. Can you please check for us @JohnR725?

I was thinking that yesterday, thats one place where epilame should be, around the backside of the impulse face .

I dont use epilame at all just 9415, thixotropic oil that changes viscosity when its struck. Epilame and 9415 = belt and braces ?

Hmm...

The viscosity of Moebius 9010 is 150 cSt at 20 °C

The viscosity of Moebius 9415 is 110 cSt at 20 °C

So 9010, which is considered a thin oil, is thicker than 9415. Can't find any info about the viscosity at impact but that should be ever lower (thinner). In comparison, the viscosity of water is roughly 1 cSt at 20 °C.

That is true H but 9415 is under the classification of a grease. Theres a lot of oils that have a high viscosity than greases which make little sense to me. But using them both the 9415 seems much thicker than 9010. Very odd, a lube discussion is on the horizon.

Might the specified viscosity rating be measured before a thickening agent is added ? Or that rating is on impact ?

I wonder if 9415 is based on a base oil of 941?

it's interesting what questions bring and the tech sheet answers it's the viscosity of the base oil. Then the impact? There is something we're missing here for that which would have a big influence on all of the house

image above is 9514 image below is 941.then always interesting when specifications do not exactly agree? They ledge above for 941 indicates 110 viscosity but the image off the spec sheet is slightly less but I guess close enough

my understanding of the concern of too much 9415 is as we know the loss of amplitude. But why do we have a loss of amplitude? So impact it's basically oil should be very slippery. But what about non-impact? Like the edges of the escape wheel?

Another thing that comes to play here is the shape of the escape wheel itself. Notice on the last a more vintage escape wheel with just a flat surface whereas the modern escape wheels usually made out of steel versus grass much much thinner their contact areas greatly been reduced and sometimes I think there even slightly curved. So is it conceivable at everything that isn't a flat surface on impact is going to be sticky? So this is where the shape of the escape wheel will have a big impact literally on how slippery things are.

Oh and for all of you obsessed with worrying about too much 9415 I never worry about it because typically I'm doing pocket watches and it doesn't seem to be an issue at all. on the other hand I'm much more concerned about a watch that keeps time for 24 hours as opposed to the concern of the group of keeping amplitude for 24 hours. Then yes some pocket watches have steel escape wheels and do look like the escape wheel on the right.

It needs to be stirred before use and that makes it feel a lot thinner than when in the bottle. Does it feel as thin as 9010 after stirring it? I guess not! Yes, it's strange!

I don't know, but if it is on impact it would make sense.

    • Where I work everything incoming watches whatever detailed descriptions are taken entered into a computer program and photograph of each item. Then ideally although it depends on who's doing the paperwork detailed descriptions can be quite good other times there lacking. Like I really like it with pocket watches if they would record the serial number it avoids confusion later on. Then when watch repairs are completed that is also entered in. It's one of the amusements I learned when I was in school instructor had a shop and commented about the important aspect of keeping detailed records of repairs. Because oftentimes a customer who got a new crystal will come back later on when the watch doesn't work and expect you to fix the entire watch for free. Then you can remind them that they just got a crystal. Strangely enough that keeps coming up or occasionally comes up where I work now. One of the problems of using the service marks on the case is that in the case of pocket watches oftentimes that's not the original case. Then case marks? What I was doing warranty work for a company I used to describe a code number in the back of the case and it would tell me the next time I see the watch that basically what I did I made no attempt at keeping track of customers because we had literally thousands of them I think they sold 30,000 of these watches and they would come back by the hundreds because they had a lifetime warranty. Yes that's a story all of itself but I would put a code number that would reference what was done to the watch the last time and think I had a date in there somehow so it did tell a story if you knew the code. Another shop I once worked out the number would reference the page in the book. So other than knowing we had been in there you would have no idea what happened because you have to go look at the page in the book to see what happened. Then the problem of how you examine a watch you should examine the watch in detail every single time to avoid complications. Although on vintage watches and this is a of amusement I have at work when people ask something and I say of the watches done when it leaves. This is because on vintage oftentimes problems won't show up until the watches much farther into the repair like it's now running and you discover things that you can't discover before because it wasn't running to discover them that also become sometimes difficult to have exact rigid prices are estimates of repairs or in the case of a pocket watch you may not find out if a casing problem to later on when you case it up in the watches running. I was just thinking for all those people that would like to leave a mark maybe you should learn to do what some of the past watchmakers did? Leave a mark but leave it in such a way that no one will ever find it? Typically not done for repair purposes but done for other reasons like identifying it's legit. I have a friend with a Gruen watch and one of the Roman numbers the bottom line that just looks like a line under extreme magnification actually says Gruen watch company or something equivalent. So here's a link showing how to mark your watch without being seen although that's not the actual title. So if you can learn micro engraving you can engrave the watch someplace probably just about any place you just have to remember where you put it. https://cnaluxury.channelnewsasia.com/obsessions/how-to-prove-if-watches-are-authentic-secret-signatures-182516  
    • I have acquired a Citizen Leopard 36000 watch. My reason for purchasing it was my desire to own a timepiece with a 36,000 BPH movement, and the price was reasonable. Another motivating factor was gaining hands-on experience with the mechanism. The watch is in good condition, but I intend to fully disassemble it for maintenance. First and foremost, if anyone has prior experience with this particular model, I would greatly appreciate their insights. I do not have access to Citizen’s specialized lubricants and will need to use the ones available to me, such as 9010, 8000, and 8300 grease. Additionally, I do not possess the appropriate oil for the pallet jewels and will only be able to clean them.
    • Hello all, I am working on an older Valjoux Chrono. It doesn't have a stamp on the movement anywhere but I believe it is a Valjoux 72. I installed the train of wheels and they will not turn. The problem appears to be the 4th wheel and the escape wheel are not interfacing correctly. I had to replace both of these parts as the pivots were broken on each. I sourced genuine Valjoux/ETA replacements. I think the problem is with the escape wheel as all the wheels turn perfectly if I remove just the escape wheel.  My question to those with more Valjoux experience is am I mistaken? Is this some other model altogether and I have the wrong part or parts?    
    • I would remove the wheels, check for damage and if not damaged, clean. 
    • Thanks for the replies! Here's a photo of the front of the clock and a GIF animation of the movement (exposed by removing the black cap in the centre of the clock). You can see the behaviour of the gears. It's a fairly valuable clock from the 80s (Braun ABW 35). I'm not sure if replacing the movement would diminish the value, so I'd prefer to keep the original parts if it's easy to fix. But since the movement itself is pretty generic, I guess, maybe replacing it wouldn't make any difference with regard to the value of the clock? Or would it? I suppose the value is mostly in the design.
