Hi all,

last year I posted this question but I had no answer... so I re-try to ask this... I'm sure that someone among the finest Heuer collectors frequenting this forum usually make movement service by themselves, so I hope someone will suggest me the answer...

On the Calibre 11 technical manual (dated 1970) four types of lubricants are quoted for servicing the movement:

- Synt-a-lube 9010 (I think is Moebius Synt-a-lube 9010);
- Bergeon KT 22 (I think is Bergeon 2588-50 silicon grease KT 22);
- Synta-visco-lube (I think is Moebius synta-visco-lube 9024);
- Cuypers no.3 (I have no idea, not found anything on the web);

Some of them still exist but my doubt is if, after 40 and more years, something better would exist? Is it preferable use syntetic or natural oil?

On a watch repair website I found this sentence: "A good general purpose oil for wrist and pocket watches is the Moebius 9010 for the balance pivots and escape wheel and 9020 oil for the larger gear train. You will need to get a grease for the winding gears and for the mainspring, such as Moebius 8200." Will you agree?

Lastly, which is a good watch parts website where I could buy those oils or their modern equivalents?

I apologize if the argument has already been treated on this forum but I didn't find any post about this topic.... I studied deeply the Cal11 technical service manual, I bought a spare cal12 movement to play with it and learn how to make movement service, clearly not to replace the professional job of a professional watchmaker (I wouldn't risk to damage my beloved Heuer watches putting my hands into them, moreover I don't own some necessary professional tools like timing machine or ultrasonic bath cleaner) but just to learn more about this argument and eventually be able to make that basic actions that sometimes could avoid professional interventions (so watch shipping - and connected risks -, weeks/months of waiting, hundred of euros spent, and so on... ).

Moreover I think that to know everything about the movement of your watch (dismounting, cleaning, servicing, lubricating, reassembling, inspecting) is the only way to avoid bad surprises when you buy an used watch (e.g. some months ago I found a complete Carrera and I bought it for a good price, and even the dealer opened the case in front of me I didn't noticed that a f***ng lever & spring was missing on the 12 hour counter zeroing mechanism, so the movement was incomplete.... if I had a bit more experience probably I would have seen the issue and decided not to buy it or ask for a discount on the final price...).

Thanks you all for reading and to everyone will help me.
