Don't kid yourself...
about those modern scientific institutions.
You won't see a thing if it isn't patented and if you want to contract research you will spend months fighting over the ownership of the IP.
The watchmakers are just little tiny children in comparison with the legal departments of the scientific institutions.
And everyone needs to pay their rent.

Testing Time: Explaining Greubel Forsey's EWT - Experimental Watch Technology
Testing Time: Explaining Greubel Forsey's EWT - Experimental Watch Technology. Spot the difference? Two 24 Second Incline tourbillons with different performances under the EWT. Which one gave the optimal performance? The problem is to know when to stop. W...
Red rag to a bull :)
Hi Andrew, Many thanks for the detailed write-up. I approve 100% of the procedural aspects, but have a few questions about some of the other points. The idea being that in the single plane, placing the watch face up on a table (perhaps overnight), or in a...
As some with more than a passing interest...
in accuracy, i found this article quite informative. I do not see much of a problem with their methodology. I wonder about the actual improvements on the wrist, versus on the testbench. Gains or losses of +/- 2 secs/day is good but not spectaular.
Agreed...
I have no problem with the methodology, and it's an interesting article, but as far as I can tell there are no absolute figures given for performance apart from difference across positions for different implementations. If they've done all that testing th...
No they cannot......
We were going to print real numbers but then, perhaps, that would help the competitors too much.......... The draft was drastically 'edited' If I spent years and resources to collect data, I would not give it to just anyone who asked. Regards, MTF
Well...
Understood, and I don't expect the the whole research database, but the observatory rating for the final product wouldn't do any harm to anyone. nick
Regarding observatory data for greubel Forsey . . .
you might just get your wish Nick.
Design of Experiments
Interesting write up. Though, their methodology does seem a little strange. If you cannot guarantee that the two pieces are exactly the same performance-wise, prior to changing one element (in this case, the angle (which actually means more than one chang...
Nice to see someone takes this seriously, beyond looks.
I've been a "fan" of both Steven Forsey & Robert Greubel for some time now simply because of this approach. They test the limits of what is known now, with traditional materials, to actually determine what values do determine accuracy in their watches. Th...

No kidding....
I agree with Don. When I worked for a 'scientific institution', we had 10x (count them!) more lawyers than clinical pharmacologists on the payroll. Funny now but not at the time! MTF
Fascinating article! Did Greubel Forsey mention...
Hello AndrewH! Thanks for the awesome report and insight into the thought process of Greubel Forsey! Did GF mention how many prototypes are built for testing and control? -MW
I have a little question about GF's innovations
I love their work but I can't help asking myself this question, and as I don't know much about horology I ask here for your knowledge. My question concerns the Quadruple Tourbillon and the differential system. The watch has 2 double Tourbillon that are co...
First, welcome! Second, some very telling questions and I hope the
answer enclosed goes some way to answering them. Two years ago, there was a chronometric competition that both MJLC and GF entered. Now, there were differences in resources each firm threw at the watches for the competition: GF took one of their Quadruple...
Thanks Andrew !
Yes it helped me a lot, considering other standpoints and path of relexion It's true too that the hypothesis can be different from a test to another, and thus may have a significant impact on the results. And thanks for the link Best, Mark
