Of my three 32xx watches, two (BLRO and SDc) experienced the amplitude problem and were 'repaired' under warranty (the BLRO went back twice as the initial 'fix' wasn't done correctly). So far, the LVc is fine. I have removed my name from any further 32xx models until Rolex (i.e. Rolex watch repairers on TRF) confirm that the issue is fixed.
I've got a hunch - and I think verv might have said this somewhere - that the issue is likelier the more the watch is worn. My (very early, so out of warranty) SD43 has always been 1-2 seconds per day slow. This thread induced me to check it again and it lost 2 seconds in two days - pretty good. But it's only occasionally worn, so if the issue is something to do with wear and tear, loss of lubrication etc, you'd expect that.
