when nothing says it all

After servicing and regulation with 'Watchguy' (thank you Mitka) my new Constellation 14381 cal 551 is currently running at plus or minus zero seconds per day -51 years after production!
-eat your heart out Rolex...

Happy? -as a pig in sh*t

I have succumbed -and the rusty seconds hand will be replaced
(but the tarnished 'Omega' will be retained)

regards

Look good, but remember to set your lift angel to 49 I can see is it set to default 52. It gives a lover amplitude at 49.

You can find the lift angels for Omega's here:

A zero rate in one single position is certainly a good start...but definitely not the end...

Cheers, Al

Zero beat error as well. Mighty impressive.

Gorgeous watch!

Here's my 564 after a visit to the same team:

The static reading in one position is going to be different than the dynamic timing and the timing when the watch is worn.

The BHI recommended practice for timing is always a gain, typically +3 s/day, then of course there is the timing in 5 positions and what those results are, and most of the time the vertical positions are quite different than the horizontal ones as far as rate goes. Then there is the reality, that being what does the watch do when the owner is wearing it, as with the variations in positions, the rate when worn is going to be different again.

The risk of timing to 0.00 rate is that the watch when worn will probably show a loss, and customers always consider a "slow" watch as having a defect or not being adjusted properly, whereas a watch that "gains" is considered as running properly.

Of course it's up to each watchmaker to adjust to the rate he's decided produces the best results.

I'm suddenly mighty unsatisfied with my +6 seconds Connie...

mactab · Oct 4, 2015

Impressive Philip.
I'm so looking forward to getting my two connies serviced in the next round of slots available. Likely to be November but it will be worth the wait. A 564 caliber and a 1011 caliber. One better then the other -who knows?

Peemacgee · Oct 4, 2015

the best thing about this forum is that in response to a slightly 'gratuitous' post you get members empathising with the small victory of seeing a watch running 'spot on'
and then you get proper technical advice from experts -which adds to everyone's knowledge

brilliant! -thank you all

BTW my other two Connies -recently treated in the same spa -are both running at +3secs/day

-now if I only knew what a lift angle was......👎

Hint: it has to do with a push-up bra.

The lift angle is the arc of the balance (in degrees) when the impulse pin (roller jewel) is in contact with the pallet fork, as the fork travels from one banking pin to the other. It is in this period of time that power is being passed from the train to the balance wheel.

The importance of this for the timing machine is that the lift angle is used to calculate the balance amplitude reading. If the lift angle is incorrect, as shown in both photos in this thread, then the balance amplitude readings are also incorrect. A rule of thumb for is that for every 1 degree the lift angle is in error, the amplitude will be in error approx. 6 degrees. So since the machine is set for 52 degrees instead of 49 degrees, the lift angle is off by 3 degrees, meaning all the amplitudes you see here are about 18 degrees lower than what the machine displays.

So the amplitude of the balance in your photo is not 256, but more like 238...if this is full wind dial down, that's a bit low for my tastes personally.

Cheers, Al

Fantastic dial.

And, how about this for a '66 Seamaster 600. Excellent work from Christian and Mitka

nice watch -congrats on that beauty

Peemacgee · Oct 5, 2015

I really appreciate the expert comments from our resident watchmakers -thank you so much (genuinely educational)
-especially the lesson on lift angles from @Archer
(although I perhaps liked M'bob's explanation a bit more 😉 )

I think we have to be a bit careful about comments on the info we amateurs have posted about Christian and Mitka's work without their knowledge or permission

the measurements shown are just one snap shot of the tests that the guys do immediately after service to show the difference between before and after

they certainly do not intend to pander to innocents like me

I know that the watches then spend several more days being tested in 'all five' positions before they are happy to release them back into the wild

I did say my post was a little gratuitous -and was intended for a bit of fun

I think I might avoid technical discussions in the future as they are obviously well beyond my current watch collecting skillets

-perhaps for the immediate future it might be safer if I restrict my comments to "ooh!, pretty!' 😟

mactab · Oct 5, 2015

Andrew , you are right. Difficult one as you posted in good faith, I would have done the same. Every expert does their job differently and I suspect there is no definitive answer?
You are happy with the result and you know that your watch has been serviced by a professional and yes the screen shot may well be one of a number of results before an average was set.
Beautiful to see all the same so don't feel bad about it.
