“How does Tag Heuer compare to Breitling?”
That I do not know, The TAG has been the most accurate watch I have ever owned.
I have a Casio waveceptor that I bought a few years ago for about $89. I monitor real time telemetry with IRIG time and my watch is ALWAYS dead on.
So I take it you like it. I'm seriously looking at a Tag Aquaracer 500m to be something nice to wear that I could later pass down to one of my sons. I really wanted a Rolex Submariner but failed to convince my wife that it was in our family's best financial interest to let me spend several thousand dollars on a wristwatch. I considered a used one but there's too many risks involved in buying a used Rolex if one doesn't do a whole lot of research.
Anyways, the Aquaracer has that classic Submariner styling and from what I've learned might just be a better watch for a fraction of the cost of a Rolex.
