before you do this look up galvanic corrosion. Some bad things bound to happen with this combo....
I think that any solutions with sodium in it between the metal will make this effect worse. Sweat has sodium..
This won't be a problem until the coating wears away from the aluminum apple watch but thats bound to happen after a few removals. It may make removing the band difficult over time too.
Just food for thought, i'm not an expert.
Note: We need women arms for these close up photos. The hairy wrists are starting to creep me out.
