·Just got a cal. 321 back from a full service. The daily rate and beat error are within spec, but the amplitude in most positions is averaging around 250 and dial up, 270. Can this be improved, or good enough? Thanks.
Following complete movement overhaul on a 321, what would cause this?

·for such an old caliber 270 dial up is good

·That’s lower than I typically see, certainly. The causes could be many things, from worn holes in bridges and the main plate, to an incorrect mainspring, incorrect lubricants used, rough or worn pivots, improper cleaning, and a myriad of other things...

·Or more likely, my watchmaker…
Your woes with this 321 are on going - like some misery that keeps in giving!😡

·Just wondering if you had the correct lift angle and was the chronograph running when you check or not?
Yes; 40 degrees, but the chrono was not running.

·I'm having a hard time finding published information that the lift angle on the 321 is 40, can anyone point me to something somewhat official?

I usually use watch guy as a reference. Not sure this is always correct, but it’s comprehensive and I haven’t faulted it thus far.

A lift angle of 40 degrees is correct for a 321.

·Al, a certified Omega watchmaker, has confirmed this many times, so that’s reliable information.

·Hello Archer, how about my case. When My 105.003 was back from servicing, the amplitude was good, it is like 300 something, but the beat error is very high, like 1.5ms, what could be the cause? Thank you!
The balance spring collet needs to be adjusted - simple thing to do for a trained watchmaker. Omega calls for max beat error to be 0.8 ms, but most opinions that I have seen would say that if you are under 2, it's not likely to affect timekeeping. Still, 1.5 is a bit too large for my liking personally.
