No instructions
Color: Black/Negative
Watch is good, but it came with no instructions bc this is very confusing to figure out. Backlight is great effect and really nice for the value. Easy to see and read

Functional and great look!

This is my third watch I’ve had in the last 10 years. I bought my first one in 2014 when I was doing triathlons. My second one just died after surfing/working in a hospital with it for the last 3-4 years. I could of just changed the battery but for $40 and it will last, I thought hmmm let’s just get a new one.
No complaints! Shipping arrived in 2 days, and the price can’t be beat. If you are looking for a simple watch to wear and not having to worry about getting it messed up this is it! I had a garmin 410xt that I had to charge etc but this watch is extremely convenient and comfortable. High recommend!
