@RufusCatWorse things to be addicted to mate.
I have stopped at 6 timepieces now.
Most I have spent on a watch was £250.
We're all in a different state of addiction, whether it's # of timepieces, cost or both. This is my collection, although it's missing 2 pieces (my EDC's).
Tread carefully and never buy a watch as some sort of investment...at best you'll get lucky and make a little; hopefully you break even but, mostly, you'll lose a little or A LOT. Buy what you like, I'm a spec geek so that's the baseline I work off and where, IMO, everyone should start (learn watch specs to decide what's important to/for you!). After that, it's how my mood is as far as type or style. I have no brand loyalty although I'm partial to Breguet for historical reasons, despite not owning one for obvious reasons; but it seems fashionable in certain circles to on them these days. As you can see, I don't own many quartz pieces as I focus on mechanicals due to having an engineers brain.
Congrats on your Seiko...solid pick.
And just to clarify...my collection is just starting. I was originally a vintage pocket watch collector. Wristwatches are my other halves fault. I was doing perfectly fine until she acted on an idea.
Happy Hunting.
