Hi Byron,Byron said:I hope that this does not sound too obvious or trivial, but may be of relevence when purchasing a vintage Omega,Rolex,IWC etc. What is the highest number of parts you have ever had to replace in the most worn out automatic movement (not including water damage)? To be more specific,how many worn parts have you ever had to replace in a mechanical movement that has been running way too long without a service?? Has it been a feasible expense to restore it to keep time accurately again with longevity?? Many thanks for your feedback
Approximately how long have these new synthetic oils replaced the previously used natural oils in Horology?Henry Hatem said:The new synthetic oils do not break down as fast or dry out like the natural oils. Natural oils dry up and the movement would stop, usually prior to serious wear. With synthetics the movements tend to keep running and grind themselves to dust. This is not brand specific.If you need clarification ask away!
If a watch were to be picking up just under a minute per day, or losing under a minute per day at constant rate, be a good indication to assume minimal wear?Henry Hatem said:If you need clarifiation ask away!
Henry Hatem said:Hi Byron -
Synthetic oils have been around for a while, exact years I do not know. Some advocate a return of the natural oils so a watch would require more scheduled servicing avoiding major wear. Oil life has caveats, synthetic or not following are a few:
Shelf life of the oil
Cleanliness of the watch prior to lubrication
Application of the oil from where to how much
If a watch was gaining or loosing a minute a day I would evaluate how long ago the last service was and the environment being worn. Most likely if the last service was 3 yrs or more it is time to consider a service. It could be other things but I am speaking in general terms.
