Product Description

Casio is an electronics manufacturing company that was founded in 1946 by Tadao Kashio. The brand has a versatile portfolio, from musical instruments and digital cameras to analogue and digital watches. The company rose to popularity quickly after releasing its first-ever product, a cigarette holder, which proved to be a huge success. Casio became involved in electronics in 1954 when they released Japan's first electro-mechanical calculator. During the “Quartz Revolution” in the 1970s, Casio expanded and became one of the first brands to create quartz watches which solidified the brand as an innovator in horological society. The brand’s timepieces are affordable and long-wearing, making them a favourite to both enthusiasts and everyday people. With the large variety of wristwatches and their commitment to progress, it is no surprise Casio has remained amongst the giants in the industry. 

G-shock is a chic subsidiary of Casio with a cult following. The larger-than-life brand image draws customer after customer who want to get their hands on an iconic piece of design.  Not only are their watches extremely distinctive but you get superior protection with trademark shock-resistance. A profusion of features, absolute daily reliability and a little bit of attitude all make for an enticing watch. A brand that has been bringing us tough, technologically superior timepieces in stylish, chunky cases since 1983.

Core Features of the Casio G-Shock:

  • G-Shock watches are water-resistant up to at least 10 bars or 100 meters.
  • The hands and the indices of the models are luminescent with Neobrite coating.
  • Incredibly durable, the watch is shock-resistant, vibration resistant and centrifugal force resistant.

Model Specifications: GMA-S2100-7AER

  • The 42.83 mm case of the watch is made of white resin. Its bezel is also white.
  • A white resin strap secures the watch.

  • For ease of reading, the watch hands are coated with Neobrite.
  • Amongst the many functions featured on the watch are alarms, a calendar and a LED backlight alongside a countdown timer function and a world timer. The model also features a stopwatch function.

I bought a Casio G-Shock as a gift for a colleague who was leaving. There was a problem with my postcode when ordering on the website so I rang the shop. The assistant could not have been more helpful resolved the issue with the postcode and offered delivery options I was not aware of. As my colleague was leaving the next day, I selected the fastest option. This meant that from ordering to delivery was less than 24 hrs and the watch arrived in time to be presented to my colleague at her leaving meal.
All in all I could not be more pleased with the service provided by First Class watches. It made my colleagues day that she got her watch on time. Thank you.
