Actually a pretty nice watch, especially for the money. Brushed stainless finish on most of the watch. Polished finished on the sides sets it off nicely. It has a rotating bezel so you can move it to align with the sweep hand for timed events. The working chronograph is similar to a Tag Heuer in the way it works. The large sweep second hand is actually used for the stop watch function with the top and center chronographs providing the 60 minute and 12 hour counters.(Actually 11 hours, 59 minutes, and 59 seconds, but if you are counting that much time do you really need a stopwatch?) The bottom chronograph is the actual second hand and is the only one you should see moving unless the stopwatch is activated. This does mean that if you inadvertantly leave the stopwatch funtion on and the large sweep hand is moving around the watch face like a normal second hand battery life will be greatly diminished. The top button on the right side of the watch starts and stops the stop watch funtion, while the lower button resets the stop watch to zero. The crown , or stem sets the time and date. The bezel is marked with 60 second calibrations, numbers every 10 seconds, 10...20...30...etc. It is also marked in degrees of a circle, 30...60...150...330...etc, as well as compass headings. S, E, W, N. And if that's not enough, it has a Tachymeter so you can calculate your speed. (Just don't try this while driving) The crown doesn't seem to be a screw down type, and the face is marked "Water Resist 100M" so I have my doubts about it's ability as a dependable dive watch. The watch diameter is about 46mm at the crown, (or stem) the crystal is about 31mm. So it is large, but not excessive. It does have heft and fortunatly a nice band and clasp to hold it on. I can't find information on the battery either on the watch or in the included instructions. Guess you wait until it dies, crack it open and get one like it. Overall a nice, good looking watch with many features if you like to play with analog devices. If you insist on using this for an actual dive watch then there is a good chance you'll be removed from the gene pool. But, if you just want a good looking, worry free watch to wear to the beach and have the ability to time the waiters, check the speed of the boats, and tell how many degrees the sun is over the horizon, then this is the watch for you.
