Bought this in June 2025, and only wore it a few times. Recently noticed the time was "off" and the seconds-hand wasn't moving. I thought it sat too long and needed to be wound up. So, I wound...and wound...and wound. Never met any resistance in the crown during clock-wise winding...just continued to spin freely, and the seconds-hand never moved. It's a pretty-looking time piece, but don't waste your money if you expect it to keep time. 👎

Great watch, terrible resizing tool.

Color: 2926 Silver Stainless Steel/Black Dial

Watch is great, feel heavy, looks beautiful in person. It shines pretty heavily. My main issue is with the resizing tool it comes with. It broke when I tried to use it. Be prepared to buy your own like I did. I can’t say how the fit is yet because I can’t wear it yet. It is not easy to set up.

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.
