CASIO AE-1500WH-1AJF  WR 100m Standard Dual Time Watch

First of all, this is not a G-Shock nor Pro-Trek, though it looks to be a hybrid of the two with cool wrist computer looking.

This probably has the best legibility in all Casio watches with its massive and crisp LCD that streches entirely of the watch face.
Even the smallest digits are easy to read thanks to clear layout.
There is a 10-second animation at 3 o'clock continuously fills up and depletes a graphic counter. 
The classic Casio visual component enables you to grasp seconds visually and also can be used as temporaly stopwatch or timer.

It is not a small watch, but resin material keeps it lightweight enough to floats on the wrist. 
In comarison with G-Shock, it wears smaller than DW-6900 and larger than DW-5600.

Functionally, it is a very rugged watch to do any hardwork with 10 year battery life and water resistant of 100m.
*New with tag, warranty, and instruction manual, only without box
