Functional and great look!
Color: Black, Color: Black
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!
