ETA 6497 base
is great and has a lot of power to drive any kind of complication. However, out of the production line, there are various points that need to be optimized such as axial looseness, position of pallets, roundness of escapement wheel... There is a big gap between a 6497 and OP... You can see it in one glance if you use a Witschi or any watchmaker timing device.
Well, of course, I am not commenting how much this optimization is priced, as a Panerai is not only a movement, but in the end I can see that both of the Panerai I have (249 & 177) are going around the second per day. Well, far bellow the 1min per day limit I target for my watches.

Anytime my friend..
Buon giorno from Tokyo Sclamb, No worries, anytime as long as I can help a fellow watch enthusiast! As for the accuracy of the ETA movement, yea I have read in many places too about the reliability, robustness & general accuracy of the Unitas 6497 based m...
Right, Stephen, I do the same
I set my 249 or any other Watch without small second, and I check each day where is the minute hand...When I go one minute faster, and slower, I divide per the number of days, and I have an average accuracy...LOL We're completely nuts! Best. Nicolas
