The watch is cool. There are a lot of reviews saying that, so I'll tell you about the downsides.
First, the watch is only for depth gauge metering and hour keeping. The depth gauge works good, easy readable and accurate. But you must know that you won't be able to use the depth gauge and the stopwatch at the same time. buuu.

Also, if you happen to use the stopwatch, this stopwatch movement works in a funny way because after taking your time, the stopwatch has to reset all the way to zero count. That is, if you timed 5 minutes, the second-hand will have to spin 5 times backwards to reset. Now if you think is of no concern, think on timing several minutes or hours!!

The strap is rubber made, but the two loops for securing it are made from some type of aluminum, so it may get you some skin irritation on your wrist (is not a material-allergy issue, but a too-hard-surface-on-your-skin issue).

Finally, the watch is a little bit too small on your wrist. Nowadays, the watches are 42mm minimum. The face of this citizen goes like 35mm.

Other than that, people will look at your watch and I've even been asked by other divers what brand is the watch because they like it.
3 stars: kind of a tie between pros and cons.
