Hvorfor og hvordan patineres skiverne

[hannover_dk]

Jo selvfølgeligt har brugen betydning, mit argument er bare, at visse fabrikkers dials (eller i visse fald visse perioder/år fra visse fabrikker) har ganske mange ure med plet patina f.eks. medens andre næsten ikke ses med pletter på skiven.

Anyway - her er lidt om skiver og re-dials jeg fandt da jeg søgte bedre argumenter end dem her med at jeg MENER det er sådan. Ikke argumenter men læsværdigt måske alligevel i forbindelsen

Her var også lidt:
over the years of service a watch dial will deteriorate due to moisture getting into the watch case. The second reason is many watch dials are silver plated and will tarnish over years of exposure to sunlight and air that enters the watch.

The dial is protected by a thin coat of lacquer when it is finished at the factory. This coating is quite fragile and will yellow with age as well as begin to deteriorate allowing for chemical reaction between the plating or painting and the substrate which is usually brass. For those of you that have ever had brass objects such as brass candle sticks, beds,etc. you will be familiar with the rapid tarnishing and frequent pitting of their surface. Watch dials are similar in this respect. They take a longer time to show the effects of age because they have a covering lacquer over the plating or painting but after time and exposure they will show the signs of aging.
