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.

Casio Men's Bluetooth G-Shock Green Solar Power Watch With Resin Strap

Very happy with my purchase. The item was at a good price and received a further discount with code. There were no issues placing the order and received regular updates on the order status.

Despite placing my order fairly late in the day, the item was dispatched and I received it the next day. Extremely well packed and have had no issues with the watch. I've only just received the item so can't comment on warranty, returns etc but my experience has been 100% positive.

As for the watch itself. I purchased it to replace my older (non solar) model. Very happy with the appearance. Setup was simple. I downloaded the app, paired the device via Bluetooth and applied all my settings/preferences. Initially the charge stayed at around Medium but, after wearing it outside for a full day the charge has reached High level and has remained so.

Many Thanks

Received the watch and the minute hand looks bent. I dont even have the option to return it!

----------

Hello,

Sorry to hear that the minute hand appears to be bent on your watch. For bent hands we would consider the watch is faulty and it is eligible to return for an exchange or refund.

We will email you a returns label link to send it back. If you need any assistance please do not hesitate to let us know.

Kind regards

Scott
