Love the zenith!
I think it largely changes for where you are in life and what you can afford.
I started with an $80 invicta when I was in college and I loved. After I got decent job and saved up I bought a Sinn 104 for about $1500. Got a promotion and sold the Sinn to buy a Breitling for $3000. This year I got a generous bonus for closing a big job and bought a Zenith defy skyline for $5800. I never really set a limit for myself its always had to do with what I like and what I can afford. I’m currently looking at a Mido multifort big date right now thats $1200, despite being less than my other watches its still on my list, price doesn’t always mean better. Watches are very personal so just get what you like and don’t worry if you can afford APs and Rolexs, there are very good watches for cheap out there and your seiko is one of them.
I’d say Tudor black bay 58, I’d definitely go with this is I was in your position. Also the Longines spirit collection has been killing it lately, so check them out too
