Query: Great watch! Great price!

This watch is great because of its practicality and convenience. It is the cheapest and smallest calculator watch out there, yet still maintains a classy and discrete feel. It is comfortable, reliable, and great for most occasions. The only problem is that the time becomes a little off by about a few seconds every week, which, if left unchecked, can add up. The calculator buttons are small, but a good size: any smaller would be harder to press, any larger would be weird. The battery crapped out about a year in, but they're so cheap, you can easily replace them. Overall, great for all purposes, a good size, and nice functioning.
