As you already figured out, I collect not only watches but also any thing related to watches…
Like spare part boxes… The nicest and coolest once are those in aluminium!
A great container to hold your spare parts dry, protected and away from dust…
Here is one of these aluminium spare part boxes from IWC. Based on the shape and size I would guess this one was made for a balance wheel.

This next one, I am not sure could be many different parts fitted into this one.

This one I am pretty sure was made for a dial, wider but flat.

Even if I do not use them for spare parts I love to collect them…
And they make great photo props as well!

Will continue to show more of these and other watch related accessories I collect… Stay tuned!
