![]() ![]() That is all for now.If I remember anything more,I'll post an addition. Patina (/ p t i n / p-TEE-n or / p t n / PAT-ih-n) is a thin layer that variously forms on the surface of copper, brass, bronze, and similar metals and metal alloys (tarnish produced by oxidation or other chemical processes), or certain stones and wooden furniture (sheen produced by age, wear, and polishing), or any. I got some moisture in the case even though I didn't submerge the watch,only fuming continuously with egg vapors and then with ammonia vapors,and now I need to open the caes and cleaned it outģ.The polished brass/bronze hands should not take a patina under normal circumstances.Those are water tight cases and therefore should be well sealed from elements getting inside the case and harming mechanism and the hands.Ĥ.Patina is a natural oxidation of those two alloys.By forming on the surface it actually protects lower layers from further oxidation,so naturally patina will form only on the surface layer and will rub off fairly easily.Actually if you don't like the results of your enforced patina you can easily clean it off with Brasso (actually ammonia based compaund,very soft,like a cream)you just rub it on with soft close and polish and rinse with water and voila- you got nice and shiny watch!ĥ.If you want to preserve patina,neutralize it with baking soda,it will stop the process.You may also apply a special varnish to protect it from rubbing off,but it will give you a "glossy" look.If you against that "glossy" look,just leave it alone,patina that is.It will settle after you wear the watch and further change coloring.I perceive this enforced patina as a starter,then just nature and the time do the trick.Yes,an exposure to the elements will do just fine but not all of us live by the seaside. Hello all!Just want to make some comments on few posts here.ġ.Brass and Bronze are alloys,both similar and different.Brass has a more yellowish color,bronze.will depend on the composition.Copper heavy bronze is of more reddish color,while Aluminum Bronze is yellow and will give greyish patina overtime.Price wise,I do not think there is big difference for sourcing the raw material for production.Bronze tends to be more expensive due to the fact that it is all "trendy" now to have a bronze watch.Ģ.I would suggest to limit your tries with submerging the watches in those solutions- LoS, Vinegar and Ammonia,you might damage the gaskets.I recently "killed" my Bob Wellson Bronze Seal.
