Feels cheap, not good for old eyes.
The watch seemed to work good. But it felt cheap, and I was looking for something with better illumination and easier to read. I ended up returning it.

Great buy!
Size: 14"-14.5" Neck 32"-33" Sleeve, Color: Black/Graphite
Got these for homecoming for my boys! Nice breathable fabrics (not the hot cotton feel). The black one easily doubled for all black attire for band concerts as well. Great price and have lasted multiple washes like new!
