Hi everyone. I currently have a series 2 SS 42mm watch and looking to upgrade to a Gold SS series 4. I found a local PVD coating company that’ll match my current watch bands into the PVD gold the series 4 comes in. Now my question is I’d like to still maybe use my series 2 on days I will be doing more labor intensive work but I’m thinking it won’t look good as all my watch bands will now be gold. So I’m thinking of also blasting my series 2 with the PVD gold coating as well. We will heat mask the screen and ceramic back of the watch but I’m worried about the internals (especially the battery) if it can handle the high temps of the PVD coating method which includes being in a coating machine that gets in temperatures up to 350-400 degrees. I know it’s risky and I’m willing to take the chance as I have a good feeling the watch will turn on just fine after the process is finished but I’d like to get some input from the community. What do you guys think should I take the risk? Yes or no why?
