## Description

Material Composition: Black plastic resin case with black plastic strap, mineral glass dial window, secured with pin buckle clasp, weighs 51 grams Design Features: Analogue-digital display with black dial, quartz movement, day-date calendar type, part of the G-Shock collection for men Functionality: Stop watch function, world time display, countdown timer, alarm function, integrated light, quartz watch movement technology Specifications: Water resistance depth rated at 200 metres, lithium battery type, resin case material, mineral dial window material construction Care Instructions: Limited coverage included, rinse with fresh water after exposure to salt water, avoid extreme temperature changes

Review: A great looking slim G-Shock watch - I was looking for a casual watch to wear at the weekend. My current G-Shock and Pro-Trek watches are a bit too chunky to fit under a shirt sleeve easily. This one however with its "Carbon Core Guard" is slimmer and much more wearable. I love the looks of this watch. The contrast of the matt black face with the green hands and markers not only looks striking, but make it very readable. Low light visibility is also fine - the hands glow a vivid green in the dark and the LED light illuminates the face sufficiently and even the LCD display to some degree. It has the usual standard Casio features, including world time, alarms and stopwatch. Being shock proof and water resistant to 20 Bar, wearing the watch in less than ideal conditions is not a worry. The only minor criticism is that the buttons are a little hard to push, although these might free up with use. Overall a great looking and very usable Casio G-Shock. For me, it's a great balance of style and substance.
Review: Great watch - A great Casio G Shock watch for the price, with all the usual functions. Strap a bit thinner than the usual chunky straps with a G Shock, but no big deal .👍

### ⭐⭐⭐⭐ Great watch
*by T***M on 6 February 2024*

Great watch, especially on offer Light Easy to read Had to have a look on line to set up but it was easy enough to find. Looks good, especially for a ‘beater’ watch. My only complaint was the delivery, I ordered from this seller as it was going to be delivered in time, but it just changed the delivery date when I checked the day before it was supposed to be delivered. So it should have been a week later but I’d did show up one day before the week was up. Shouldn’t be allowed to post a date and then just change it.
