Casio G-Shock Men's Watch GST-B100XB-2A

Features

From G-SHOCK, the watch brand that is constantly setting new standards for timekeeping toughness, comes totally new G-STEEL designs that combine different types of materials.
This new model come with metal parts and buttons, and offer a choice rose gold accent coloring on the iconic disk dial at 9 o'clock. The colors of this watch give it a look that is both sporty and elegant.
The bezel of the GST-B100XB models has a highly fashionable design, and is made of lightweight yet very rigid carbon material. Combining state-of-the-art Toray Industries TORAYCA®*1 and NANOALLOY®*2 results in a bezel with outstanding shock resistance characteristics. Highly scratch resistant clear sapphire glass is used for the crystal to enhance readability and appearance, and to create a design that is both tough and good looking.
The hefty urethane band features a sporty outer surface pattern that improves its fit and looks great as well. A metal band ring reduces the chance of band breakage due to abrasion.

*1 TORAYCA®: High-performance carbon fiber material by Toray Industries is used in a wide range of applications, including: aerospace, high-pressure vessels, wind power generation, automobiles, bicycles, golf club shafts, fishing rods, and more.
*2 NANOALLOY®: Original Toray Industries nanometer structure control technology makes it possible to combine multiple polymers on a nano-metric scale (one billionth of a meter) for performance that is far superior to previous types of materials. This polymeric material enables high performance and high function that was previously not possible with standard micron order (one millionth of a meter) alloys.
