Amplitude seems low on a serviced watch.

·Recently something like this happened to me and ended up being a dust filament inside the movement, stuck between the escape wheel and the top jewel. The kind which you see floating in the air sometimes

·The watchmaker will have the watch back to replace the defective aftermarket crown. He is going to double check the amplitude. His claims it is a combination of multiple old parts. It is keeping time well though in all positions. I'll keep you posted. I did find a original crown in and stem on the plus side. Took some research though. Found a different caliber movement that used the same parts.

·you should have a clean line on the timegrapher. Something is wrong.

·It's not uncommon for the hairspring to be suffering from fatigue or rust spots on a watch that old, which will cause low or erratic amplitude. Going from the trace, there is possibly a bent pivot on one of the wheels. Also the mainspring if not genuine or even genuine but old stock, may not be supplying enough power. Lots of reasons why it may look like this though including the typical combination of worn out bits. Very few independents will change worn parts out for new ones unless they are actually stopping the watch from running.

·cracked jewel, bent or used pivots, hairspring, mainspring, bent wheel, used balance pivot. It can be a lot of things.
Seing the curve, it's probably not (only) the mainspring as the curve would be cleaner.

·Did you visually inspect the movement and then benchmark the watch on the timegrapher before you sent it out?
This would provide clues, but no certainty, about what may have occurred when the watch left your hands.
Does the watch have a fixed or mobile stud carrier?
Could the watch have been damaged in transit on its way home?
It's good that the watchmaker volunteered to have a second go at it.

·Did you visually inspect the movement and then benchmark the watch on the timegrapher before you sent it out? I documented the timographer readings or bench-marked it. I didn't want to open the case until the watchmaker takes another stab.

Does the watch have a fixed or mobile stud carrier? I don't know. I have attached a stock photo of the movement if it helps.
Could the watch have been damaged in transit on its way home? It was very well packed, and I assume that it was not. Especially with the good time keeping.

Thanks.
