Wasser&Brot Posted October 9, 2015 Report Share Posted October 9, 2015 Hello i want to ask u to help me with 1 of my QC pictures.. The Aplitude seems to be too high (333*) or am i wrong? Would u accept ? Greez from Berlin- Germany Gesendet von iPhone mit Tapatalk Quote Link to comment Share on other sites More sharing options...

SSTEEL Posted October 9, 2015 Report Share Posted October 9, 2015 Reject on that basis, you are well within your rights as a buyer to do so. Quote Link to comment Share on other sites More sharing options...

themannier Posted October 9, 2015 Report Share Posted October 9, 2015 A good amplitude is between 280 and 300, so ask for another watch maybe Quote Link to comment Share on other sites More sharing options...
Raxford Posted October 9, 2015 Report Share Posted October 9, 2015 I understand the range we should be looking for, but if the ideal amplitude is a max of 300, what does this actually mean for watched with amplitudes of 310, 320, 330? Is it the end of the world? Is the watch left inaccurate? In need of servicing? I had a watch come in at 321 and I understood that it was over the recommended amount, but I didn't really understand what it meant for my watch.Cheers!Rax Quote Link to comment Share on other sites More sharing options...
mymanmatt Posted October 9, 2015 Report Share Posted October 9, 2015 Amplitude is the distance in degrees that the balance wheel travels before it stops and starts the other direction. The average swiss movements come in at 310-320 Quote Link to comment Share on other sites More sharing options...
ceejay Posted October 9, 2015 Report Share Posted October 9, 2015 To high an amplitude and the impulse jewel will start hitting the pallet fork causing knocking and inaccuracies in timekeeping.Anything higher than 315 degrees is cause for concern, normaly too high an amplitude indicates a problem with the mainspring providing too much power. Amplitude with 333...run away! Quote Link to comment Share on other sites More sharing options...
Wasser&Brot Posted October 9, 2015 Author Report Share Posted October 9, 2015 Thanks for ur answers! My movement is the Asian 2836-2 25J automatic movement at 28800vph.. Just for the Info Gesendet von iPhone mit Tapatalk Quote Link to comment Share on other sites More sharing options...

ceejay Posted October 9, 2015 Report Share Posted October 9, 2015 When you look at that trace above everything looks great. But that watch isn't moving, once it's on your wrist and moving about, a bit of extra inertia (?) and that can start knocking NOTE: I have seen twice recently a rather cunning little 'scam' regarding amplitude. Top right of the trace is the lift angle, this can be set manually and will affect the amplitude reading. It should be around 52 degrees as above. The 2 I saw recently had higher lift angles programmed which had artificially raised the amplitude Quote Link to comment Share on other sites More sharing options...

ceejay Posted October 9, 2015 Report Share Posted October 9, 2015 No, it was M2M sales over RWI & RG Quote Link to comment Share on other sites More sharing options...
Raxford Posted October 9, 2015 Report Share Posted October 9, 2015 No, it was M2M sales over RWI & RGOk good. Well I've definitely learned something. If you have a watch with a higher amplitude, I imagine it can be tuned, right? Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
ceejay Posted October 9, 2015 Report Share Posted October 9, 2015 Sure can & on some of the higher end timing machines you don't have to have the lift angle displayed.The vast majority of people just have it set to "Auto" the timing machines normally have the lift angle preset to 52 degrees so just mount the watch and away you go.Antique watches etc can have differing lift angles as does the Gen Omega Co-Axial watches. That's when you have to manually change the lift angle. And before anyone asks, no I am not going to try and explain what lift angle is!

Thanks for the wisdom ceejay et al!Hopefully this thread will help others out, too. I'm sure it will.
