Guys! I wonder if You can help me:)

Iam getting new watch from TT, got the QC pics.

Do You think the Amp number is too high?

Just got a PO from TT & my Amp was 325 & watch seems fine

I know this is not an exact science with the timegrapher results.

I am just probably worrying too much:)

well its a 6497mvmt, those are strong and reliable mvmts and last a long time

Thanks troops, I am gonna go ahead with it!

Thanks MD!

Good explanation, I remember read it before but it always good to hear from experienced horologist:)

Can't wait now, my first Pam:)

That is a bit high. 325 is generally considered the upper safe limit so the balance wheel does not knock.

I just hope the amp is high being on timegrapher only a short time and will go down a bit.

Amplitude
The measure of the amount of rotation in the swing of the balance wheel, in either direction.
Amplitude is higher when a watch is lying flat and usually falls when the watch is in a vertical position, due to increased friction. Amplitude can also fall as the watch winds down and the mainspring delivers less power.
Amplitude is a good indicator of the movements health and if is too high or too low, or that changes too much in different positions, can indicate a problem with the movement.

great : 270-310
acceptable : 250-270

If higher / lower?
Ask for a different watch or have your watch serviced
