This is a well balanced watch with lots of style and solid bling. It is a functional scuba watch, chronograph, and extremely fashionable watch. I prefer the 51-30 Chrono more than the 51-30 Tide because this watch is more practical. In addition I have peace of mind knowing the watch is operating because the second sub-dial is continuously moving: the Tide has no second hand movement.

The continuous second hand is actually the top sub-dial, the large sweeping second hand is part of the chronograph. This feature makes the chronograph more functional since the second hand countdown can be used with the external rotating numerical bezel. The watch also comes with date, a minute count sub-dial and 24 hour sub-dial.

You can use the large sweep second hand continuously but you'll shorten the battery life. When you reset the chronograph it's awesome to see the big second hand sweep reset to zero.

The Japanese internal mechanism and durable gold case exudes quality build throughout. The stainless steel case is nicely sized at 51.25mm wide with 934 feet (300mm) water resistance. The crown, at 9 o'clock position, and the two chronograph buttons must be screwed down in order to maintain the amazing water resistance.

The watch band is a beautifully styled custom solid stainless steel link with double locking clasp with visible screw heads at both ends of the case. Once the band is sized you can do minor adjustments at one end of the locking clasp.

A bold, awesome, powerful look plus practicality equals an incredible watch.
