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 wants 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.

This is my second G-Shock watch. My first one is worn on most days, is durable, excellent quality, keeps spot on time and I've not changed the battery yet after 8 years. So I bought this for occasional use. It has all those qualities plus I like the yellow colour, although it isn't as bright as it looks on the website. I did have an issue at first, which I had read about in a review, being that it can be difficult to read the time depending on the angle you look at the watch or the quality of light. I resolved this by downloading the app and making adjustments to the light length of time and when it is activated. The app is good to make all kinds of changes to the watch eg 24 hours rather than 12 hours view. I did email First Class Watches with my issue and got a very quick response. I'm really happy with the watch.

Ordered a G-Shock solar (first one, getting fed up of winding and setting time/date on all my mechanicals) 14:30hrs and received the watch next day. Great service, kept fully updated throughout the process by email from clicking buy to having the watch on wrist. Good price when compared to other retailers online and in store. Will certainly look here for my next watch.

I already have an old G Shock Protector and hoped this Yellow version was going to be a suitable upgrade. The watch is great to look at, but sadly misses the point of being a watch as the display is so dim that I cannot be read immediately. I either have to use my other hand to press the illuminator button or turn the watch to a different light angle. So its back to my 6 yr old G Shock, it is scratched and tatty but does tell me the time at a glance.

Great little watch. I know the negative display isn't everybody's cup of tea, but I like it. Quickly despatched and well packaged.
