Sinn UX: Nice watch, crappy movement!!
Discussion
Had my Sinn UX for just under a year now and whist I absolutely love the design and style of it, I have to admit that I am really not overly impressed with the movement.
In particular the second hand, which suffers quiet noticeable 'bounce back', and the second had doesn't line up well with the second marks on the face (the degree to this mis-alignment changes as the hand moves round the face).
Am I being overly critical, is it reasonable to expect more from a circa 1500quid watch??
Having seen some mention of this elsewhere with the UX, would I have a valid complaint if i was to pursue it as the watch has done this since new!!

There is a reason for its 'bounce'.
1. A battery change requires sending back to Sinn for the oil change.
2. Therefore they want the battery to last longer than normal.
3. They use a low-torque design so the interval is about 7 years (iirc).
4. The hand moves oil, then the oil back-fills the voids, this 'bounces' the hand.
It's a thrermocompensated COSC quartz, so not a crappy movement in actual fact.
"I made my last pilgrimage to Sinn today and talked to their Service Manager, Sebastian about the much maligned Hydro bounce. Sebastian said that the drift is mostly positional and is caused by the resistance of the oil. He said the hand pushes the oil ahead of it on the beat and between the beats the oil following in the wake pushes the hands forward until the pressure dissipates, that’s when the hand settles backward slightly. He said this could be overcome by using a movement with more torque but the life of the battery would be greatly reduced. He said this was the best balance their engineers could arrive at and still maintain COSC accuracy."
I like that answer, if there is an 'engineering' justification makes it much easier for my 'engineers' mentality to accept. It does keep very good time it has to be said!1. A battery change requires sending back to Sinn for the oil change.
