  1. Well, it does Work! (thanks Rob for the tip!) After less than 3 days the stem is totally dissolved! There was a bit of black grit in the tube, but after a quick ultrasonic bath, the crown has no signs of the broken stem inside! The only noticeable affect on the crown is a slight darkening/staining of the surface. I'm not sure if this is a result of poor quality stainless steel(cheap Chinese reproduction) or if this will happen to any stainless steel. I d0 think I can clean the surface back to, or close to the original satin finish. One of my other concerns was that this crown has a spring inside to allow for a water-tight seal when the crown is seated home by use of the crown guard lever(remember it is a Panerai replica). As I cannot inspect the spring to check for damage, There does not appear to be any change to the spring strength itself. The process I used was to dissolve about a tablespoon amount of Alum in a small amount of water ( I will not attempt to explain the amounts further in metric or US measurements as I'm sure I will confuse everyone reading! :huh: ) and kept it heated by sitting it on a radiator/heater for the duration. I had to add water once as it will evaporate quickly under these conditions....

  7. Typically these 1 jewellers are pin lever movements and the solitary gem is the balance cap jewel on the balance cock. The cap at the other end of the balance staff is a hardened steel plate, and all of the pivots run in plain bearings. The rationale behind the use of a jewel in this particular location is that most of the time that the watch is not on the wrist it's likely to be sitting dial up (on the bedside table etc), with the balance staff vertical and spinning on the jewelled cap, with wear concentrated at that point. With the watch on the wrist its orientation is constantly changing and so wear is more evenly distributed. If steel were used for this bearing then the staff could effectively drill its way through. That being said, Timex do seem to have solved the problem with their zero jewel "V-conic" escapements which just keep going with minimal, if indeed any, maintenance.
