    I’m so happy Tissot came out with this movement!
    Beautiful classic beauty! I love watches with internal components that far outperform the price. A certified chronometer for 1100$? Unheard of. From a Watchmaker like Tissot? I couldn’t buy it fast enough! It has great accuracy and a very durable time tested movement. I can’t wait to own this watch for the rest of my life! Tissot, just keep putting this movement in more watches and I’ll keep buying them. (Seamaster or Submariner competitor please!)

    It’s different colors in different light
    Very high quality. It’s not a Rolex knock off , it’s a date just “style” just like the diver watches. They are not Rolex knock offs but in the same style. To be honest, I owned a blue date just brand new from the dealer and sold it because I could not read it ! I’m able to read this with its Roman numerals as opposed to the Rolex Baton style markets . It’s COSC CERTIFIED! I am just impressed with the blue version I own . Dial is beautiful.
