base calibre ETA 2836-2

[jukka]

Hi

I such bought watch(Revue Thommen Airspeed 16005.2) with base calibre ETA
2836-2.
I wear my watch only day time and leave it at desk for nights.

Now i have problem that it stops about after 14 hours and advances about 20
seconds
after i have started it again.
Manufacturer told me that after the watch has stopped i should turn the
crown 6 times and then the spring should be fully loaded for 38 hours power
reserve.

Actually how many times should i turn the crown?
Any other helps?

Regards,Jukka

Dear Jukka,

As a rough guide, the watch will run about one hour for each turn of the
crown.

Some autos are not efficient. If you have a watch that does not auto-wind,
just turn the crown and consider that the watch is a manual wind. My two
cents.

A couple of items here.
1) The ETA 2846-2 has a micrometer adjustment. You can easily adjust the
watch to run within 1-3 seconds per day by making small adjustments to the
regulator.

2) The amount that the watch has an error depends to a large measure on
what position you place the watch on the desk ..... dial up, dial down,
crown up, crown down, and so on. The best way to adust the regulator is,
as in 1), the time on the wrist.

Not true, but not bad advice. The automatic wind mechanism on your watch is
probably working.

On my good Swiss auto watches, I generally give the crown 10-15 turns in the
morning, which is enough to get through the day, and puts the mainspring in
the middle range of winding (lifting, hoisting).

Enjoy the watch.

I disagree with your recommendations - both to consider a watch with a
non -working auto to be a manual and wind from the crown and your suggestion
to wind 10 -15 times each morning.

Unfortunately, the ETA auto winding system is poorly designed in some
respects. Ideally there should be a clutch that disengages the auto train
when you hand wind but the ETA system has no such clutch so every time you
hand wind you are placing the autowind system under stress by running it
"backward" all the way to the reversing wheels (and sometimes beyond if the
lube is poor) and causing unnecessary wear. I confess that when I put an
auto on in the morning I have the bad and so far unbreakeable habit of
giving the crown 2 or 3 half turns but even that is too much. One of the
reasons the cheap Seiko movements often run for up to 20 years w. no service
is that there is no hand winding system present so there's less opportunity
for the user to break the watch. The best treatment for an auto wind watch
is not to wind it from the crown at all.

Hi

It's a pity because i like this watch outlook.
Some years ago i had Breitling Colt Automatic and it also stopped(Breitling
promised 42 hours power reserve)
during weekend when i was not wearing it.I do not know if Breitling uses ETA
calibers.
I sent it to factory repair but returned with same stoppings(<40 hours)
I sold it to my frend and bought 50 euro Casio quartz.One exception was that
Breitling did not advanced with time.

Now same problem with Revue Thommen.

(I saw one advertisement from Blancpain that they have 5 days power
reserve,but this timepice costs 12000?.)

An automatic watch needs some movement to keep wound. Basically, a
weighted rotor or pendulum inside the watch winds the spring as you move
your arm. No moving, no winding. Do you lead a very sedentary live? I
recall a comment from a disabled person that he didn't move enough to
keep an automatic watch wound.

I would wind it the minimum number of turns to ensure the watch functions
to my satisfaction. If you accept that advice you will have to determine
that number for your own situation.

Some say that you should not hand-wind certain automatics because of the
wear on the auto-winding system. I am certain that the point about wear
is accurate. However if you have the watch already and if you like it
enough to want to keep it then you have options:

1. Worry about the wear, dont hand-wind it and keep a watch that does
not function to your satisfaction.

2. Wind it just enough to make it work properly, accept that there will
be wear and that you will have to get the auto-winding system repaired
at some time in the future.

I would personally regard option 1 as unsatisfactory. But you have to
make up your own mind.

Owning a mechanical watch is going to cost in terms of servicing.
The cost of that has to be accepted. It comes with the territory.
Option 2 will cost some more, but is, to me, the only sane way forward,
assuming, again, that you like the watch enough to want to keep it.

On top of that, exists the pros and cons of 'winders'.

I think Jukka is worrying too much. The number of hours that the watch runs
after putting it on a desk is not the top importance.

If a watch runs and tells the time, I will not return it for repair, I
think.

[Jack Denver]

The OP's post is a little fractured but I gather that the watch is stopping
overnight so it is NOT keeping time for him - it sounds like he is wearing
it less than 10 yrs on, 14 hrs. off . It may be that there is nothing wrong
with the watch, he's just not wearing it enough and /or is not active enough
during the time he is wearing it.

OTOH, it is possible there is some problem with the autowind system so that
it's not achieving full power reserve. If this was my watch and it was
under warranty I'd have them check it.
