What time do you wear?

I'm so used to wearing Omegas I forgot to say.

I bought and sold watches on ebay so I was able to keep a lot of very nice watches.

A few years ago I got the nicest Omega I had ever seen, it was one of the Aquaterra Tonneau solid 18k that normally has an alligator band at $8500, this one had a solid 18k band and listed at about $16,000, weighed 4.5 ounces, a truly gorgeous and elegant watch. Got it on ebay for $3500 which is what the one with the black strap should have gone for, it had never been worn or sized. I wore it for a couple of years for dress, figured I'd sell it if I could get $8k and it sold for $9500. I still wish I had that, but I needed the money at the time. When you are buying and selling things for a living you can't get attached to something you can make that much on.

Casio GA1000-8A.

I had picked up a domestic Japanese only limited edition Mr G on ebay, they were not available in the US at all, even the instruction book was in Japanese only. I liked to use it as my barbecue watch as it had multiple timer functions.

So my wife and I were in a watch store and the sales clerk behind the counter asks in a super excited voice, "is that one of the real Mr G's, oh my god I've never seen a real one". My wife's eyes sort of rolled and she told me it must be a guy thing, which is what she says about audio, cars, tools, etc.

Help me out, people ! I am so stressed that I can't even listen to any records. Need a gift for a close relative. Can't decide, Omega or Breitling ? Both have an appeal. Consider Breitling Seewolf and Superocean models or Omega Planet Ocean and Aqua Terra. I know nothing about watches.
Aesthetics is important but reliability and performance are much more important, including waterproofness and shock resistance. Not for deep diving, mostly for everyday wear and occasional outdoors.
Would really appreciate your thoughts.

As far as desirability among watch aficionados and retained value I'd definitely go with Omega over Breitling, but both make fine watches.
