First "nice" watch; am I missing any options?

[dannyboy2233]

Hi all!

Longtime forum reader here. I'm a huge watch fan but new to collecting, and I'm currently looking to buy my first "high-end" piece (meaning ~$5k price range). I'll likely be buying grey market/second-hand, as I plan to keep this watch indefinitely and I'm not too concerned with perfect condition/full set/resale value/etc.

My current "collection" consists of a 1967 Omega Seamaster DeVille dress watch and a two-year-old Seiko SKX 007 (my daily). I live a very active lifestyle, so I'd rather spend my money on a SS/waterproof/semi-indestructible piece I'll be able to wear like my Seiko. I like classic designs, and I am a bit partial to dive watches (recently got PADI-certified and I love the idea of mechanical robustness).

That being said, I've compiled a list of potential purchases that are within my price range. They include: Omega Speedy Pro (recent w/ sapphire sandwich), Omega Seamaster (oldish w/ blue wavy dial), Grand Seiko Snowflake (SBGA211), Cartier Tank Solo, JLC Reverso (probably would have to be pretty old), or Tudor Black Bay (new).

I've ruled out a Rolex, as it would be too flashy for someone my age; I'd rather no one know I'm wearing $5k on my wrist :)

Current rankings: Speedy in first; it's a true classic, I've loved it for years, and the sapphire sandwich looks beautiful and more robust than the Hesalite crystal. Second is the Seamaster, which I've also liked for years, but which on off days seems a little tacky (I can't tell if the waves look as good as I think they do). Dark horse is the Grand Seiko; spending $5k on a Seiko would be a tough mental barrier for me (especially for my first higher-end purchase), but I'm obsessed with the mechanics of the Spring Drive movement and the SBGA211's finishing.

If anyone can think of something I'm missing or should consider, I'd be happy to hear it. This will likely be my last purchase for a while. Thanks in advance!
