I use HP 1300 (instead of D5) on higher grade movements such as 2892 and the Dubois Depraz modules, as well as HP 500 in place of 9010 (except on balance end stones where I still use 9010).

 

Your list looks good.

 

I did a small list in this topic also. http://www.watchirepairtalk.com/topic/83-lubricants/#entry310

I took note of that list you shared, I will see which can I take to try my very first service, I´m making a list of materials and basic tools to perform thee task. Thank you all for your posts!

Hello all,

I'm about to service a Timex 260 electric movement.  It's running strong as-is, but I doubt that it has been cleaned or lubricated in its lifetime.  I do have the service manual for the movement and for most of the oil points, the SM calls for Moebius Synt-A-Lube, without specifying a product number (I intend to use Moebius 9010), but for the friction pinion the manual calls for "spreading type oil" (Woods AAAA oil).  I cannot find a cross-reference for this old Woods oil and most watch oils are, of course, specifically formulated to NOT spread...  so, I'm seeking advice and suggestions for a suitable oil to use on the friction pinion.  Also, if anyone thinks that 9010 is NOT appropriate to use for the various other points, please let me know.

Thanks much!

Ben

Thank you for your suggestion, rogart63.  You may be correct about the Epilame, but I'm not sure that's what they are referring to in this instance. The manual recommends stripping the movement only so far as removing the balance wheel and bridge -- then cleaning the remainder as a unit, and finally applying the oils -- so if a person follows this procedure, I can't see any reasonable way to get an even coating on the relevant part.

I have attached a screencap from the service manual, showing the location where they want the "spreading oil" applied (it's marked as "A").  The impression I get is that they are calling for an oil that will wick into gaps.

I can see how a grease might work here, though -- thank you for the suggestion.

They probably mean something else? Something that will spread around under there? Have no idea actually? 

Maybe could dilute 9010 with Naptha so that it spreads more easy?

Thank you both for your replies.  I had a chance to begin stripping the movement apart and I found that I can actually gain good access to the friction pinion by disassembling the movement just a little beyond the officially-recommended degree of disassembly -- and by doing so, I'll be able to oil it directly with 9010 rather than hoping that the oil will spread to the proper area.

@Marc Funny, I was expecting 9010 for the pivots (instead of 1300), those devils are spinning! But I would be wrong (I checked the service sheet ;) The big speed is a relative one (between each two in each set). The entire reverser wheel speed is quite slow, so 1300 will do!

Thank you for that!

I am having trouble getting Lubeta into Australia as Cousins UK and Cas-Ker US wont send as it is dangerous goods. So I might have to make up my own Epilame of 9010 in Naptha if I can find the right ratio. Member Rogart63 suggested it might be 100 to 3 . 3 parts oil to 100 parts of naptha. Thoughts?

I understand you have to mix those two, but how do you actually do that in real life?

I believe you have to make a large quantity (with some sort of seringe). Because if I count 100 drops of naphta, they will be gone by the time  I finished counting :)

I have a relative who is a vet and who is practised in mixing small volume mixtures in mls. I am seeing him tomorrow (Aussie time) so I will ask unless it's resolved here in the meantime. I don't believe it's done in drops but in volume measure.

That stuff evaporates faster than an open bottle of scotch that's for sure. :) I am assuming naptha is the american for lighter fluid right?

I'm pretty well set up for oils for wrist watches, but not so for pocket watches.

I'm yet to buy Moebius 9020 which I will be buying on my next order from Cousins.

I've just cleaned and serviced an 8 day car clock which I'm guessing is from the 20s or 30s which is essentially an oversized pocket watch.

Can I get away using 9010 on the pivots or should I wait until I get 9020?

Also I currently have 9415 for the pallets which I know is the recommended oil for watches over 19,800bph.

Should I also be investing in 941/2 for the slower beat watches, or will 9415 be ok too.

If you want to stick with Moebius use  clock oil 8031.

I always preferred JD Windles Clock Oil for all clocks apart from clocks that had a platform escapement, then it would be a watch oil but not too thin.

I have read that 9415 is especially developped for high speed escapement, and can cause loss of amplitude on slower beat watches. For that reason, after a long time using only 9415 on pallet stones I have recently invested in 941/2. 

It is a lot thinner than 9415, but I can't say that I have noticed a difference in performance. I wanted to experiment with both on the same movement and measure the difference but haven't got arount to it yet....

As for the car clock, I have worked on a few and i used 9010 on the balance jewels, and D5/ HP1300 on the rest of the train with no issue, I could not justify yet another type of oil for this application, the clocks I was workin on were not exactly high end!

I had never heard of JD Windles Clock Oil before, so I looked it up.

The price is certainly good so I have added that to my list for my next order from Cousins as I'm not completely happy with the oil I have been using on clocks and 50ml should last me for ever.

    • I've remained silent on this thread, and at the risk of upsetting everyone, the thing that worries me the most the the apparent absence of Mark. The moderators do a great job and the members also pitch in, and the site seems to run itself, but it is a concern for the future of this forum when the owner is absent for all intents and purposes. Like many of the comments above I would hate to log in one day and things be closed down as I rely on this site for ideas and knowledge and also cheer me up. maybe the Moderators could reach out to him, assuming he does not read this thread, and express our concerns and let us know the plans going forward? some kind of WRT ark
    • That was the exact reason for me starting this thread watchie. Still we haven't worked out how the regulars are going to hook up if it goes tits up. I honestly think something should be arranged to stay in contact, we all help each other so much. 
    • Yeah ive watched that a few times before,  i couldnt find my old school dividers to scribe it up 😅 Yep thats the guy i bought a roll from . Thanks Nicklesilver that answers that perfectly and more or less what i thought an experiment over time would prove . The jumper arm is quite thick along its length, i left it that way intentionally, i thought the original was probably very thin, i didnt see that it was already missing. Setting isn't particularly stiff as such just positive, i still need to take it out and polish where it mates with the stem release. 
    • Yes, "Sold out" is difficult to understand. There doesn't seem to be a lot going on. It's been nine months since any new video was published on the Watch Repair Channel. The Level 4 course on watchfix.com has been in progress for what feels like forever (several years!?). Maybe Mark's enterprises aren't doing well or perhaps already so profitable there's nothing much to motivate him for more material. Or, perhaps these days he's more into crochet. The real reason is probably something entirely different but it would be nice/interesting to know. I don't mean to sound gloomy or pessimistic, but I wouldn't be surprised to be met by an HTTP 404. Every day feels like a gift. Speaking of watchfix.com I've been postponing the "Level 5: Servicing Chronograph Watches" course for a very, very long time. Anyway, I just enrolled on it so it's going to be very interesting to see the videos. I must say, IMO there's nothing really that can compete with Mark's courses when it comes to presentation and video quality. It's simply world-class and makes me associate with some really expensive BBC productions.
    • Steel has some funny properties, or at least counterintuitive. The modulus of elasticity is effectively (not exactly, but close enough) the same for steel that is annealed and hardened. What changes is the point of plastic deformation* . If the movement of your spring doesn't pass that, it should work fine. It looks a little thick, I would thin it a bit maybe from the main body out about halfway, maybe 10-20% thinner (not in thickness, along its form). But if it works it works!   *So- if you have two bars of the same steel, one annealed, one at 600 Vickers (general hardness watch arbors might be), clamp them to a table so the same length is hanging out, and put a weight on the ends, they will bend the same amount. But if you continue to add weight, then remove it, at a point the annealed bar won't return to its original straightness. That's the point of plastic deformation. But up to that point, as springs, they are the same. However- their wear characteristics will be very very different. And getting the hardened bar past its point of plastic deformation takes a lot more effort.
