I think the power reserve is about 40 hours. I wear it Monday to Sat for about 10 hours a day. Come the following Sunday afternoon it goes slow then stops.
I was going to give it a top up, but some say manual winding is not good for this movement.

one other thing I forgot to mention.
On the timegrapher face up, it's a consistent plus 6 sec per day.
When I change it to crown up is loses about 10 sec per day.
So there is big difference between these two positions which don't effect my other watches.
The Omega Aqua Terra is more or less bang on in all postions.

Since I started this thread, it's now dropped to minus 69 sec per day.
Surely it must stop soon.

Still going and now minus 75 secs per day and that鈥檚 with the dial up.
Crown up it's minus 120secs per day.
Loving this Timegrapher. 7.20 uk, now at minus 80 .secs.
Time, 7.30 uk Minus around 82 secs.
Time 7.40 Uk minus between 85 and 95 secs.
Time 7.55 Uk minus between 91 and 99 secs
Amplitude now 153.
Crown up minus 141 secs, amplitude now 133.

Note sure what you are trying to accomplish here, but timekeeping is typically checked on a timing machine at zero hours (full wind) and then 24 hours later. If you are measuring well after that, it's not unusual at all that the timekeeping will start to vary a lot more.

If you want to take a set of readings at full wind, and then 24 hours later, I can look at the numbers and tell you if I think something is wrong.

Please provide rate, beat error, and amplitude for all 6 positions, at those 2 states of wind.

Thanks for that Archer, much appreciated. The watch is still running at 10.30.
It is now at @ minus 164 secs per day. A short while ago in went up to over 200.
Not sure why this is but the amplitude went up to over 300 at one point, it's all over the place at the moment. I鈥檒l take the readings you suggest and post them for you look at.

When you say full wind, would this be about 30 or 40 full winds of the crown?
The watch stopped at 10.55.
I'm going to start the watch by shaking it a few times, then wearing it for a couple of days and put it on the Timegrapher.
Then I will wind it fully, check the results as you say and make a note of them and again after 24 hours and see where we are at then.
I know I'm being a bit geeky over this, but it's all part of the learning curve.

Ok, here goes, first off I restarted the watch by shaking just enough to get it working.
On the Timegrapher Dial up it was -145 secs amplitude 320 beat error 0.0.
Crown up it was - 210 secs, amplitude 251, beat error 0.4.

Fully wound, 40 full turns.
On the Timegrapher
Dial up +16 secs, amplitude 282, beat error 0.0.
Dial down + 15 secs, amplitude 283, beat error 0.1
Crown up +5 secs, amplitude 274, beat error 0.1
Crown down + 12 secs, amplitude 279, beat error 0.1
Crown at 9 o clock + 8 secs, amplitude 269, beat error 0.1
Crown at 3 o clock + 6 secs, amplitude 271, beat error 0.1
Hope this helps, I'm not going to wear it and I will check again at 12 hours and 24 hours to see where we are at.

Thanks for all you help.

Just wait until you start looking at your watch with a 10x loupe. Then the shit will really hit the fan 馃榿

Nothing unusual there - you have a 10 second Delta between the fastest and slowest positions, which is good for a movement of this quality.

Ok, 24 hours later.
On the timegrapher

Dial up - 1sec, amplitude 247, beat error 0.0
Dial down -6 sec, amplitude 250, beat error 0.0.
Crown up -18 sec, amplitude 233, bear error 0.2
Crown down -11 secs, amplitude 244, beat error 0.2
Crown at 9 o clock - 19 to 26 secs amplitude 232, beat error 0.2
Crown at 3 o clock -19secs, amplitude 234, beat error 0.1.
Big differences from the fully wound position.
Also I checked it at 12 hours and it had started to slow down then.
Obviously there is some variation so I have tried to give the mean rate.

One hour later

Dial up - 8 secs amplitude 226, beat rate 0.0
Dial down -12 sec amplitude 237, beat rate 0.0
Crown up -34 sec amplitude 224, beat rate 0.2
Crown down -21 secs amplitude 222. beat rate 0.1

The watch is clearly losing time well before the reserve is low.
From what I can see it looks like the watch starts to lose time from the moment it's wound up.

Over the 24 hour period left dial up on the Timegrapher the watch has run 10 secs fast.
Next stage it to wind it up fully and wear it for a couple of days and see where we are then.

That's a rather dramatic shift in timekeeping, so yes there's definitely something going on there.

Any any Idea why?
It's still slowing down as we speak.
It's now at minus 11 sec dial up and minus 29 sec Crown up.

Amplitude drop is larger than normal, and isochronism is larger than normal. Although related, there are somewhat different reasons for both.

Could be a lot of things - to properly diagnose would require having a watchmaker take a look.

Thanks, like I said, it's only 18 months old. A while ago I tried to adjust the time by mistakenly moving the beat error lever. The balance wheel stopped for a split second but seemed to have started up again ok.
I've since reset the beat error and looks ok as far as I can see.
I'm going to try it on the wrist over the next few days. I'm waiting for it to stop to see how much reserve it has when fully wound. I wound it 40 full turns, would that be fully wound?

After 31 hours Crown up is at -36/42 secs amplitude is 215 beat error 0.2
Dial up it's - 12/14 secs amplitude 226, beat error 0.0.

Yes, should be.
