    Stunning Gentleman's Watch
    Color: Grey
    This is my second Tissot watch. It's quite stunning in person. The online photos don't do it justice. It has the look and feel of a much more expensive gentleman's watch which makes this purchase a great bargain. Tissot is a great reliable Swiss made watch brand. My first Tissot watch which is probably more than 20 years old still runs great. Very pleased with this purchase.

    Good Tissot Watch
    Color: Grey
    Arrived on time, in its original box, include a 2 year international warranty, into the box include a book with the Tissot brand history in Switzerland. Algo a second book with a whole catalog of Tissot watches men and women. The watch looks better when you put in on your wrist. The “naval” blue really gives the clock a classy look. The stainless steel workmanship is really good, the metal is bright and perfectly polished. The metal wristband quality is very good, did not have any problem to adjust the size , I went to my preferred clock workshop for this job, they extracted a few pieces of the band to fit to my small wrist size. Have to get used to the butterfly latch, but after a few days, now I learned to open and close it without any effort. The clock it’s very accurate, I’ve been using my Tissot for near a month and it just increased a few seconds per week. I do the setup and check accuracy with my pc clock. In short, It”s a good value watch, nice, good looking, accurate.

    Stunning Automatic Watch With TopTier Durability and Precision
    Color: Grey
    “I got this Tissot PRX for my cousin’s birthday and bro fell in LOVE instantly. This thing keeps time like a beast, never slows down, never lags. Automatic movement, so no batteries, no drama. Durability? Stupid good. You can hit it, bump it, live life rough, it still looks box fresh. Size wise it was almost perfect. I just had to remove two links, nothing big. It’s light, functional, comfortable, doesn’t weigh you down, doesn’t get in the way but more importantly I can say this watch is in everyone’s eyesight when we wear it. Cause of course I had to get another one! Basically. I gave him a very nice piece as a gift, and now he’s walking around like he owns Switzerland.

    Excellent value for an automatic watch, keeps VERY good time.
    Color: Grey, Color: Grey
    I've only had the watch for a day but wanted to leave a quick review on it to share a couple of notes. So far it keeps VERY good time, better than any of the automatics I own (including a Rolex Submariner, Tag Heuer Aquaracer, Tag Heuer Formula One, and several other sub $1k watches). I set it to an atomic time app on my phone yesterday and 24 hours later it's still SPOT on - hasn't gained/lost even a 1/10 of a second. I was shocked to see it's kept PERFECT time for the last day, I'm really blown away so far. I've worn it the entire time, we'll see how well it keeps time while being stored in a winder. This picture shown is the watch with a 22mm leather band on it, fit's without any issues (just need to squeeze in the leather a tad). I doubt it would work with a 22mm metal bracelet, but leather works great. Just FYI since the 21mm lug width is kind of odd. The face isn't quite a lustrious as the images make it look, but it's still a great-looking watch. For a sub $1000 automatic you can't go wrong, this is a fantastic watch at a great price. It'll be my daily driver for some time I'm sure. If I have any issues in the future I'll update the review.
