I was a bit skeptical about how good a $40 watch would be, but am pleasantly surprised. The overall presentation, especially the font and the metal case, is handsome and appealing to look at. The version that I have is the no-frills Sea Wolf: it only gives the time - no chronometer, stopwatch, day or date. But that's really all I need.I appreciate how Calibre apparently created a multi-tier product line not by cutting manufacturing quality from the base models, but instead by removing features. In other words, the build quality I think is exactly the same between my time-only watch and a more expensive chronometer-and-date watch.The back side of the tail end of the band is ribbed, which seems to help prevent it from coming untucked. That's a nice touch.Neither the item description here nor the product manual indicate anything about battery replacement or winding. There is no apparent way to open the case, and so I have to assume that it is self-winding based on wrist movement - which is great! That's what I want.The bezel rotates counter-clockwise (anti-clockwise). It's probably intended for divers who need to track minutes, but the manual doesn't talk much about it.I really enjoy wearing it, and only docked it one star for a few minor reasons:- It is a bit on the heavy side- The reflective bits on the hands are really tiny and so are hard to see when I wake up in the middle of the night- Calibre's website seems like something a coding-boot-camp web developer could write in a weekend.really like this watch. great value / very comfortable to wear / easy to see time / basic and does what a watch is for /Tell timeGood looking watch that I wear every day. Band is comfortable, and watch feels and looks well put together.This product seems exactly as I expected. There is no problem and I am happy with this purchase. I did not use it yet because I am on vacation, but I can see the high quality.Good looks; nice weight, reliable movement. It's a great watch fro the price.Loved it. This is my daily watch and have to admit it, I never get bored by its look. This is very rare. Trust me :)This watch is the best watch I have ever purchased. It functions well and really looks great. Highly Recommended for anyone looking for a great watch!great watch
