Need luck ...
Heard from several friends with mixed results too.
Mine is alright till now, +3 to +6 per day comparing to atomic clock ref. You can use time.gov as a reference if you can set both watches correctly 
Better to time them if both have enough power ie. after setting correctly, wear them for a few hours then start to track.
Still look forward to more of your results.

Initial comparisons between 2 Sistem 51s time keeping accuracy
Be assured that testing is being done under the strictest of conditions in accordance to the Kew observatory, COSC, and whatever the Germans call their chronometer test facility in Glashutte. I welcome anyone who would like to send their watches to Knoxvi...

So on a cost-adjusted basis it's (dollar for dollar) more accurate than a Patek tourbillon? (",)

That remains to be seen but you are on the right track
with your thinking. Just as we have atomic clocks and such for reference time keeping, we need to find out what the true or reference value of a second/minute/hour is. If one pays $250,000 for a Patek grand complication (with a tourbillon) and it loses 5 ...
Clearly, the timing discrepancy is due to . . .
. . . phase shift in the visible color spectrum reflected onto the crystal from the case. The Helmholtz-Doppler alcohol-by-volume test is predicated upon this phenomenon. First observed by Prof von Finestein . . . . . . and honored by the Nobel Committee....
Thank you for clearing that up
I think as we delve into this more deeply a large number of horological questions may be answered. Perhaps even some metaphysical answers will be revealed as well. I do need to report that our initial timing test has ended due to the fact that my wife wan...
