Welcome to WatchProSite!
Welcome to WatchProSite! And congratulations on your first post!
1. Yes, that is considered oxidation. This is considered VERY MINOR oxidation.
2. The oxidation should slowly go away after some use. If it doesn't go away, there are some generic liquid cleaners that can remove the oxidation. Definitely go for liquid cleaners, avoid cleaners where you have to rub or apply as rubbing removes a small layer of gold. Servicing wouldn't be needed for this level of VERY MINOR oxidation.
3. To prevent this in the future, consider the following... 1. Wrap your watches in plastic film (the one you use to wrap food is good) as air tight as possible. Consider putting some plastic between the bracelet so the bracelet links don't rub against each other. Try to get all the air out, it's the air that causes oxidation. 2. Also, considering you live in Singapore, a fairly warm and moist country, your safe might need to be equipped with a dehumidifier. Consider a reusable desiccant that you can put in the safe to reduce moisture inside the safe. This may help reduce the oxidation. There are some desiccants that come in a small metal box (with little vent holes) and the metal box can be heated in a small oven every month to dry out and "recharge" the desiccant so it can absorb more moisture again. 3. Use your watches more often. You're probably rotating through multiple watches. If you rotate through them frequently (like wear a different one each day), you're less likely to see oxidation on any one watch.
