Post by Anthony FremontPost by Frank AdamLow friction escapement makes a watch go longer between services ?
Didn't Omega raise the service interval from five to ten years? This
might be a really stupid question, but isn't it a key point that the
coaxial escapement doesn't require oil on the jewel surfaces?
No, because the escape wheel pivot still requires oil and most watches
that come in stopped, will be due to a frozen/dry pivot or some dirt
in the train. What Omega did with the coax, is that they've improved
the time keeping of the watch between services, since the escapement
will function well with even reduced power from the train.
the 5 year has always been the recommendation because of the oil life.
In fact, Omega is not even one of those rare models which wear at the
pallet stones, they wear in the train and this is usually due to that
fact that well designed watches can operate for 10+ years, so
customers who don't get flustered by their watch starting to drop or
gain a few seconds a day(a clear sign of problem) will not bring it in
for a service and let it run dry for another 5+ years or more.
I feed on snippets of info like this. Please feel free to elaborate
like this at any time, it's appreciated.
Post by Frank AdamMaterials and finishing processes of parts have improved so much that
the 10 years now can be valid, especially in quality time pieces, but
i am still sceptical about the oil condition at around 10 years.
Synthetics art the way man, stop being so "old school". (;-)
Post by Frank AdamAnother thing to keep in mind is, that Omega expects most of the
coaxes to go back to them for service, because they are a somewhat
finnicky thing if anything goes out of alignment and because of that,
watchmakers might think twice doing them. As such, worn parts will not
be a problem, since they do change those routinely and all inclusive
in their price.
Now that makes sense. It's sort of a planned obsolescence kind of
thing. Something like auto manufacturers suggesting 7500 miles for the
oil change interval, yet I can think of only one oil company touting an
oil with that recommendation.
Post by Frank AdamPost by Anthony FremontPost by Frank AdamSo the oil is briefed about this and told not to deteriorate at it's
usual rate ? Amazing technology. ;-)
I don't claim to be a watchmaker, but I do know that oils in general
have improved drastically in the last 60 years. It doesn't seem
unreasonable that organic oils which lasted for five years, have since
been bettered by synthetics that will go much longer without gumming up.
Yes, synthetic oils have increased oil life by a large margin.
Post by Anthony FremontMy motorcycle sure appreciates the difference between "dino" oil and
synthetic. I wonder if Royal Purple makes any watch/clock oils. ;-)
Jeeezus man, how can you be using motor oil with "purple" in it's
name ?! ;-p
I'll tell you how. It works, and it works well. Next to Red Line
racing oil, it's probably the finest stuff in the world. Unlike with
Red Line, you can find Royal Purple on the shelf if you look for it. It
really is purple too. There's some real truth in advertising on that
one.
Post by Frank AdamUsed to be Castrol GTX when i was real macho with my really cool matt
black muscle car, but now it's Mobil 1 for the tame little family
sedan. Tastes much much worse than the GTX did though. :)
I used Mobil 1 for a while, but my engine made too much internal noise
with it. I'm not saying that it didn't lube as well as the Royal
Purple, just that the internally generated sounds were louder. In fact,
I'm reasonably sure that as far as engine wear go, there would be no
distinguishable difference between the two synthetics. So, like most
people, I made my choice by completely arbitrary and unscientific
methods. It's quieter, and I happen to find the color irresistable.
;-) I pick synthetic oil purely for technical reasons. My engine is
air cooled (actually oil cooled, but most people don't get it),
synthetic has a much higher smoke temp. It also makes the engine run
cooler (presumably from lower friction, but who is to say that it
doesn't transfer heat faster to the engine casing).

Post by Frank AdamMost of the dust, with the exception of the wear-in metal dust under
the crown wheel, is off the guy's bench, lamp, clothes, dandruff,
whatever. Stirred up probably while he was setting up the camera for
each shot.
I can't wait to find one of these in a pawn/thrift shop to perform my
own autopsy. No offense intended towards anyone but, with issues like
this, I like to see for myself when possible.
Indeed. The reason i've made my counter statement is that i don't like
pre judgements made on things, based on just a few pictures and
without any reasonable proof, be it for or against. Even better,
seeing the item in question personally will be the final proof.
I'll agree that judging from a sample of one is risky at best. However,
if I should randomly take one apart and find similar levels of filth,
I'll probably put allot of credence in that. No matter what, even the
oldest and cheapest watches that I've taken apart have higher levels of
finish quality on the faces of the wheels.
As dAz pointed out, there seems to be a missing tooth on an intermediate
wheel. The OP apparently didn't find it laying around anywhere inside.
Maybe the wheel was assembled into the watch with a broken tooth and it
resulted in all the metal dust and wear? No matter how you slice that,
it seems to bring their quality control into question. Unless you find
that kind of thing frequently when working on Swiss watches? :-?
Post by Frank AdamIf tomorrow i get one in and i do find that it's a piece of shit, rest
assured i won't have any problems reporting it right back here, but
until then, with all my experience thrown in, i can not say that it's
a bad watch or a good watch.
I can certainly assure the AH community that it *is* a watch. :-)
Yes unfortunately the requirements, for many items deemed as watches,
seem to be quite minimal. ;-)
