: 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.
