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.

Excellent product, super good quality
Color: White, Size: Large
I think this is one of the best products I’ve bought on Amazon in recent years. I recommend it 100%; the fabric has a soft, comfortable texture, unlike other Oxford fabrics, which tend to be thicker and stiffer. It is easy—very easy—to iron, and the sizing is spot-on; I wear a size L, and it fit me perfectly. I will definitely be buying this shirt in black and navy blue.
