Through out my lifetime, I do not expect myself to buy a lot of watches. However, every one of them I owned, I have worn them for quite a long period of time and therefore they are all memorable for me.
So I decided to take time to build a nice wooden case to store them all, because they certainly deserve it.
Everytime I set up a terrarium, it never lasts longer than six months without a lot of maintenance. This is the first time that it does. No fungi or mould has been found inside the bottle. I am still wondering why.
Perhaps the environment inside the bottle is simple enough. Maybe it was placed on the right spot in my room having ample light but not direct. Or maybe it has something to do with the temperature.
