Up for discussion is the viability of self service on a Sinn oil filled watch.
I think I would enjoy owning a Sinn quartz watch, but for whatever silly and stubborn reasons I have, I just won't send it back to Germany for a battery change.
Sending it back is not an option and will not be considered.
So, what would happen if a UX was opened, completely drained, cleaned and then reassembled? Would it run?
Sinn and articles I have read state that the oil causes the watch to be more legible especially under water and not crushed at great diving depths.
For this posting, I believe a UX would have suitable legibility without the oil and I rarely dive to depths greater than 300 meters (actually 1 meter is my record) which is easily reached with a normal run of the mill dive watch.
So, why would the UX not run without any oil in it?
2nd question. Why not change my own battery and refill the watch with 100% silicon oil myself? Would worst case would be a bubble that may be annoying?
Several posts speak of the factory fill being silicon oil, so if very carefully opened and refilled, what could go wrong?
I know that is remote that anyone has tried this and we are all speaking from opinion and guessing, so let me hear your ideas. And if anyone finds a great deal on a used UX and wants to try this. please let us know your results.
