6R15 amplitude record

Who can beat this?
To be honest it only last few  seconds after full winding.

You're competitive, yes!  Well let me see....How's this:

Its a Valjoux 7750 sitting on the instrument in the foreground. I'd just overhauled it , and it was almost fully wound.

Aren't Swiss mov.s supposed to be over 300 deg or the watchmaker confined into the lab until exhaustion?

Not a record but a good average!

Just getting there....

Some Seiko's are just amazing. Unmolested 7S26A from '99 (or 09?).

This is a report of my dg2813 with gmt and date complication after 9 month non-stop wear.

Surprising is that the values did not change until this period.

Did You set the lift angle correctly on the timegrapher?

Machine default is 52 while Seiko is 53. Thus mismatch causes like 1 or 2 degrees difference. The computation was posted by John in another thread.
