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.

Really cool and beautiful watch. Although my specific unit runs 5 seconds fast every day—at first it’s annoying, but eventually you stop caring. 🤣

A Beautiful Timepiece at an Awesome Price!!
Color: Grey, Color: Grey
I have lusted after this watch for four months. I first tried on a similar model (stainless steel band with a green face) in a local jewelry shop (Spitz Jewlers, Walnut Creek, CA, USA). It was "love at first sight," even if I didn't love the white lines on the face from 12-6 and 3-9. At the time, the MSRP was $775. The MSRP has since increased to $795. But I bought this beauty on Amazon.com for only $524.99; after applying the cash-back from my Prime credit card, this watch costs only $498.75. This was "the offer that I could not refuse," to quote from "The Godfather." Accuracy could be better: after only a few days, it is now 7 seconds behind my phone (to which I set my new watch). But I don't really care about that all that much. This is why I rated "accuracy" at 4 stars, but my overall review is 5 stars. My video shows the date changing suddenly at 11:59:59pm, just how I want it; in another photo, you can see that my Seiko changes the date more slowly, which I do not like. This watch is absolutely phenomenally beautiful. If you're on the fence over whether to make this purchase, then I would say "go for it!" You will not find a prettier, more accurate watch at a lower price in ANY store in the entire USA.
