Cleaning my Regulateur

Hello! I have a beautiful IWC Regulateur that I wear consistently and it needs to be cleaned (exterior). What is the best way to clean my watch without damaging the metal?

Here's what I do >>>>>

I just use a microfiber cloth (like the ones that come with sunglasses or similar) to wipe down and clean the crystal and case.

If there is any 'grime', I will us a wood toothpick tp gently remove the build up and then wipe clean.

Since we're not talking about a crew-down crown or sports watch, I would not get to too close to running water, LOL!!!

It works for me!
