I've recently obtained an old cleaning machine (an L&R Master from probably around the 50's). Two of the jars don't have lids, though. Would it be okay to get around this problem by putting plastic wrap or something over the jars when not in use?
Hi jdm, thank you for your interest. I have worn this wonderful watch every day for nearly twenty years and there is a fair amount of play in the bearing, not rubbing against workings or caseback yet, but noisier than it used to be.
