No budget? Patek 5231. Sure it'll cost ya 100k, but you can turn around and sell it at any time for 100k so... isn't it basically free?
Watches
A community for watch & horology discussion.
Tudor Black Bay 36 or 39 or vintage rolex airing (34mm) or vintage OP (36)
Rolex Datejust if you can afford it, or Omega Aqua Terra, or if money is a hair tighter than that, Christopher Ward Sealander or Dune.
Look at Grand Seiko’s. I have the snowflake, but many other excellent choices. Excellent quality, beautiful craftsmanship. As good as Rolex (fight me) at half the cost.
Everyone is going to have a different idea of what signals solid quality without ostentation.
If I see someone wearing a Seiko, Citizen, or Hamilton; I assume they know something about watches but don’t care about watches as one-up-manship or display.
But then, I’m more interested in a well cared for Honda Fit than in a new Lamborghini, so take that with a grain of salt.
