Today when switching to another band - I found out, there is a freeplay on one of the band shafts rod. Try to diassembly it and found out something like a small rubber in watch housing. Was courious if this can be production error/difference between shaft rods, so diassembly the next one (withou free play) as well. There I have found something like a torn o-ring. When remowing it (it will anyway fall out sooner or later) there is a same free play as on the first shaft rod.
I have watches one year, I do not see any big issue with this freeplay, but hole for shafts starts to be a bit wornout.
Do you have any freeplay on shaft rods? Do you thinkg, new o-rings should be instaled?
