For those of you keeping score at home, this is my current collection.
These are my two boxes. Yes, there's a third, with less interesting pieces in it (like the gaytona ...) but these are the primary and secondary.
This watchbox is the primary box. Normally, this is where I decide what to wear.
This is the secondary box. The less-worn stuff lives here. Yes, there's a watch missing. It's my SFSO that would normally take the place of the 1665 in the primary box, but Mrs Pugwash's dad has nicked it.
Sometimes watches migrate from one box to another. It's amusing to try to track the migratory patterns, but ultimately it's a futile exercise.
