The watch is precise, easy to read and the glass is properly resistant (mineral?). The battery is not too expensive (4), and I think we can replace itself. Sufficient seal for current splashes, rain and sport. (Not tested real capabilities underwater, but I would tend to trust the advertised 30 m). Silicone bracelet has the advantage of avoiding having to "tinker" links of a metal bracelet. The watch is very light and comfortable to wear. The chronograph is classic and works flawless. I think at this price, this watch is a much better choice to watches cheap copies of large brands in the often precarious reliability reported in the comments of some uitlisateurs
