Low amplitude on new movement

[MarkF]

I recently disassembled, cleaned, re-assembled and oiled a new st36 movement. Once everything was done I put it on my timeographer and adjusted it to get the beat error under 0.2 and the rate within +/- 2 secs in the face up position. However the amplitude gets to at best about 260 degrees and falls off when I rotate the position. After about 24 hours the amplitude drops to about 210. 
 

The pivots on all the train wheels appear to be fine. I oiled the pallet stones, though I used Moebius 9010 instead of the recommended oil - which is on order. Not sure if that would have any effect. Mainspring is new - shouldn’t be the issue. 
 

Where should I be looking first?  Or is 260 degrees about as good as it gets with this type of movement.

as it was a brand-new watch what was the watch doing on the timing machine before you serviced it?

Then is the lift angle set correctly on the timing machine

Lift angle is correct at 44 degrees. Prior to servicing the amplitude was about 250 - so I got some improvement, but still below the targeted 270+. My understanding is that many st36 movements are not properly oiled when they leave the factory, so the low amplitude prior to servicing could just be the result of poor lubricación.

you're right the lift angles 44° because this is a clone of a ETA 6497-2.

then technical specifications watch companies are interesting because they don't have a target amplitude only people on discussion groups do. They're concerned with timekeeping and minimum and maximum amplitude in specific conditions. I snipped out it the technical to show you this.

Cool. Thanks.
