Congrats on the new watch, Joe, and a big welcome to the forum! :-! The Tissot V8 is a nice, clean and classic style. Which color did you get?
Citizen and Seiko produce watches at many levels and offer something for just about everyone. Their watches are respected for design and overall quality and generally represent good value in the watch world.
Tissot fills a much smaller niche than Seiko or Citizen. They cheifly aim at the mid-price level somewhere between say $300-$1000. Their product line and number of units produced is a very small fraction of Seiko and Citizen's. Tissot's quality is very high and they have a 150 year heritage that has garnered them much respect. They are currently owned by the Swatch Group, as are Omega, Oris and several other Swiss brands. They use ETA movements (also owned by Swatch). Tissot is generally admired by collectors for offering high quality watches at exceptional prices.
Hope this helps, and enjoy your new watch!
