Review: Love this watch - Great watch. You'll want to Google video instructions on how to set time because the instructions that come with the watch are not awesome. But the watch is cool and durable. The backlight only affects the small digital readout.

### ⭐⭐⭐⭐⭐ Love this watch

Great watch. You'll want to Google video instructions on how to set time because the instructions that come with the watch are not awesome. But the watch is cool and durable. The backlight only affects the small digital readout.

### ⭐⭐⭐⭐⭐ Quality

Excelente product

### ⭐⭐⭐⭐⭐ Love The Options
*by J***F on September 19, 2023*

Pros: Fits my 7-1/4" (7.25" / 184mm circumference) wrist quite comfortably with plenty of adjustment. I like the octagonal bezel with many different options of color and and dial. I enjoy the various modes it offers. It's nice being able to see UTC time and have timers as well as alarms. Since it's quartz/battery driven, I like not having to wind it or often adjusting the time compared to mechanical watches. Cons: I wish the hour and minute hand had a brighter luminescence but the on board light helps in the dark. It's also difficult to read the screen from 17min to 25min. Even worse from 3:17 to 3:25 when both the hour and minute hand are blocking the LCD screen. Overall: I love the watch. It has its minor issues but it wouldn't deter me.
