This watch is big (50mm case diameter) and heavy. As I wear it I can feel the good material used to craft this watch. The watch itself is waterproof and suitable for divers for several reasons.

The watch can be used for diving in up to 300feet (although I didn't dive this far). The design is simple yet elegant, and easy to see. High contrast between the background and the dial makes it easy to see it underwater. The outer ring on the watch's face is marked clearly with big numbers and ticks indicating the number of minutes you've been underwater.

Another good feature on this watch is the stopwatch/chronograph function. The big second hand you see in the picture (pointing at the twelve-o'clock) is dedicated for stopwatch function. The minutes elapsed is indicated by the upper small dial that moves minute-by-minute. This way, it's easy to see the minutes and seconds elapsed when you're in chronograph mode.

One thing lacking when you get this watch is its manual. The small booklet is a general guide for several Invicta watch models. As such, you'll need to find the right one for your watch by matching the given diagram in the booklet with your new watch. Aside from this, everything else seems perfect.

Overall, the watch has a quality build and features for divers with big wrist.
