路I've gotten better from a 7750, so what's your point? 馃槈

路路Omega Qualified WatchmakerCome on, you know you can't get better than this. 馃槈
Maybe you can't...
Yes I adjusted the average rate after this...but last time I checked a Delta of 1.6 was better than a Delta of 2.0 馃榾
Oh and this was an Omega Cal. 1152, so a non-COSC movement.
BTW is that your timing machine? I would not think a service center would allow those to be used...

路I care only about time on my wrist. My GMT Master II and my Date-Just are within 15-seconds per month! And my 45-year old non-chronometer Air-King Date is within one minute per month. Not that these rates would please everybody! 馃槈

Well what a collector considers okay and what a watchmaker does are often 2 different things. Since I have no idea how picky the person I'm doing the work for is, the only option (for me) is to make it as good as it can be. If the person doesn't care about timekeeping, then they certainly won't be disappointed.

Well, you can't either: your maximum amplitude difference is 32 degrees... 馃槑

No, it is not: I am bound to use Witschi. Hovever, we have more than one bench and not the financial capabilities of Swatch Group. 馃槈
Kidding aside, I find most modern Rolex calibers very well engineered, precise and reliable. As such, I cannot agree with your previous statement. And, please, notice that I have no special affiliation with Rolex.

I never said they weren't well engineered, reliable, or accurate. They seem to have mythical powers over people (even some watchmakers I guess) but in terms of accuracy and reliability, there are plenty of calibers that can equal them. As I said, they are nothing particularly special, and I stand by that. You are certainly entitled to disagree, but cherry picking an example doesn't really prove your point.

To make clear my position, if I were asked to indicate my preferred caliber, I would indicate the ETA/Valjoux 7750. And if I were asked to indicate my preferred watch I would say the IWC Da Vinci from 1985. Both of my picks (caliber and watch) do not encounter the favour of the "experts". However, I am confident that all of them have never overhauled a Da Vinci.
I suspect that in this respect our respective positions might not be too far apart. 馃槈

Maurice

路路Omega Qualified WatchmakerI don't think anyone is saying this fake is the equivalent quality to a genuine Rolex movement (not that those are anything particularly special really anyway) but that the appearance is certainly there to a large extent.l

No, they are not particularly special.
Okay well this was productive...馃う

路Hi Al and Maurice.
Nice results! But, when are you going to show some at full wind (0H)??!!
Seriously, you've given me something to aim for now especially as I don't believe either of these has the latest top hairspring technology and materials.
What would you be aiming for at +24H? Half as much delta again? A lousy 馃槈 3 or 4 seconds?
Cheers, Chris

Hello Chris,
as you know, the maximum rate difference is related to the amplitude and, at least with respect to the vertical positions, it attains a theoretical minimum at 220掳. This said, it is quite common to find movements which perform better at +24H than at full wind.
Let's add that a perfect balance posing can nowadays be obtained by means of laser techniques which go beyond the possibilities of any workshop. Nevertheless, a very good result can be attained at the bench with experience a a lot of patience.
Cheers,
Maurice
