You're going to Texas ... deliberately?
😉
I'll give you the benefit of the doubt and pretend that's a jab at the obscene weather we've been having. It's calming down some lately, though.
It was somewhere between Hitler and Stalin bad. Now it's somewhere between Pol Pot and Papa Doc.
Moreover, I'm not a hundred percent sure Austin is part of Texas, anymore.
OP - Tourneau no longer has a location in San Marcos. In fact, I think they left TX altogether. That would've been the best bet on used, I'd think.
Hour and a half/ two hours south, in San Antonio, there's an Omega Boutique, a Breitling shop, and Lee Michaels. The latter is an AD of TAG Heuer, Tudor, Rolex ( *chuckle* ), and others. There's also a jeweler called Gurinsky's that has stuff on consignment. I handled a 14060 and an older GMT Master there a couple days ago. Plenty of Sub Dates and DJs as of about a week ago, if that's your thing. A few Omegas, too.
Other than that, it's three hours north to Dallas or two and a half east to Houston ( turns out it's a big state...) for
really fancy stuff and more ADs.
There has to be a particularly good reason for me to go up to Austin these days, but that's cos I got in on the last of the old times, when there was a good band in every place on Sixth Street and there were interesting and bona fide talented musicians, hippies, and burnouts. Not just goons being weird for the sake of it.
That said, a good time can still be had, but be mindful of AGGRESSIVE panhandlers that turn up now and again. It's not unsafe, just irritating.
