### ⭐⭐⭐⭐⭐ F91 but better!

### ⭐⭐⭐⭐⭐ Great purchase

Great watch, Mine broke pretty quick but the store I bought it from replaced it with no hassle. This watch is a great purchase if you're looking for something that's simple and stylish that you can wear pretty much everywhere

### ⭐⭐⭐⭐ A reliable cheap watch
*by P***E on 3 September 2025*

I've been using these for years, a reliable cheap watch. They last about 2y, when the strap breaks. I am not a large person by any means but I only get to use the second hole on the strap. The last one had a fault oh the LED display but was replaced promptly by the seller. I will continue to use this watch and regard it as a disposable item, replacement straps or batteries are not economic to consider.
