Seeking advice. (Wall of text followed by some images.)
I have a brand new Clean 116500 with Dandong SA4130 movement.
Amplitude is maxing out at 356 degrees when fully wound, dropping back to 345 after around 5 minutes, with the dial up or down.
It remains above 340 for the next 5 hours or so with the watch is sitting dead still. After 8-10 hours of stilling still, amplitude is between 300-305; once it’s been on my wrist for ~10 minutes, it is back up around the 325-330 mark. Another hour on the wrist (basic movement around the house or walking around outside) and amplitude is back around 335-340.
With the dial up/down, but rotated 45 degrees either way, amplitude is almost exactly the same. With the dial to the side, crown up or down, amplitude figures reduce by ~15%. Timegrapher lift angle is at 52. Adjusting the Gain makes zero difference.
When the watch is fully wound, the beat rate drops to -12/15 secs p/day. After several hours, when amplitude is back down around the 300 mark, it gains 12 secs p/day.
With the watch at my ear in multiple positions, I cannot hear any Knocking; I hear a very clear tick tock with no galloping sound or anything like that. The Timegrapher line doesn’t appear to show any knocking, and I’ve had the watch on two difference Timegraphers. All other movements I have are within normal ranges on these Timegraphers.
Winding the watch feels normal, but the potential problem is that it always feels normal – even after 60+ manual winds, it doesn’t feel like the spring is slipping. All other functions of the watch appear healthy, pending a power reserve test, which is in progress right now.
Given the width of the end of the pallet fork, I can’t see how the impulse jewel could possibly miss knocking into the outside of the fork at a 350+ degree rotation. (Looking at the CTime 4130 Gen vs Clean comparison, I looks like the SA4130 doesn’t have single banking pin which the gen does. Or whatever the pin in the image below is.)
Even if there is no Knocking, is this a ticking time bomb? I imagine that, like a fuel powered engine, if you run it at 6K RPM all the time vs 4, it’s going to burn out faster.
It may be that the mainspring is too powerful and needs replacing, or braking grease isn’t applied properly. There could also be a speck of dust under the pivot jewel acting like a ball bearing. Who knows.
Either way, I don’t have the skills to remove and replace the barrel complete or anything else this might be, and I don't want to void any warranty). There are no watchmakers in AUS who will work on the 4130 (other than replacing the entire movement), so my only options are to pretend everything is normal and see how it plays out, or I return the watch to Andiot for warranty repair or replacement of the entire movement (which Elliot already confirmed).
Sending a watch back to China is not considered a sensible COA. Any suggestion or guidance would be greatly appreciated.
Just typical - the first Daytona I've bought in 15+ years and of course it has a bloody fault.
