I understand you're limiting your watch collection, but have you considered limiting it to just Seiko or Omega?
Seiko would be cheaper and they are heavily reliable and have a huge range of watches to suit your needs, or maybe even a single watch to work for everything you do.
Sane with Omega, except obviously it's more expensive.
Honestly there's a lot of brands to choose from to suit all ranges of activities and it takes a lot of thought to purposefully limit your watch collection.
Not sure if that made sense but essentially I'm saying to think it through, the German market isn't my forte but I would just go with watched that as you say reflect who you are.
Regardless of market or brand.
EDIT: Just like the gentleman below, one watch for all occasions is the best, although you'll very rarely find one that will do just that. But when you do, you'll form an amazing attachment to it and it'll essentially become an extension of you; it sounds weird but it's true!
