I had been eyeing this watch for a while. It commands quite a price for a Quartz. I have several Casios and all are perfect examples of the incredible functionality and value Casio is built on. The Oceanus line was intriguing as a high finish option. The S100 is better than hoped for. the Crystal is stunningly clear, imparting an entrancing blue hue to the black dial and wonderfully dimensional polished indices. I chose the S100 over the T200 for the lines and proportion of it. you do loose ability to swap straps, but I find the integrated strap to be more than enough and perfect as a part of a unified whole. All the current Oceanus watches have to many complications for my taste. This one is simplicity, refinement and dignity worthy of such a God-Tier watch maker. Get this while you still can.
