In-Depth Review of Casio B640

Size & weight

The watch weighs only 58 g, so you will barely feel anything on your wrist. Also, with dimensions of 3.39 x 3.62 x 3.46 inches, it will come in handy when choosing the type of clothes for business occasions.

Other Casio models like G-Shocks with sporting styles seem to be a burden for people with small wrists. However, with Casio B640, this unisex device will be your choice in this case.

Case

This item case size is also quite reasonable, with the case thickness of 1 millimeter and the case diameter of 35 millimeters. Moreover, the case is designed after classic Casio models and comfortably sized like previous timepieces. The case is made of solid resin and has an appealing applied finish that matches the steel bracelet.

However, you should know that the watch might not survive some beatings since this is not the kind of watch with a high level of shock resistance. So if you want to maintain the case properly, make sure to avoid some high-intense activities.

Water resistance

Although the water-resistance level of the watch is only 50 meters, you can wear it when taking a shower or swimming. It is known as one of the typical features of these Casio lines. However, you should consider not bringing this timepiece with you for diving or other water activities in a deeper level of water.

Movement

Quartz movement often goes with many Casio line products. And this Casio B640 is not an exception. Therefore, the accuracy is improved remarkably for +/-30 seconds per month.

Another advantage is convenience. A watch with quartz movement, along with battery change every couple of years, will continue to function without the need to wear or wind it. Finally, you can save some money since quartz watches are less expensive than mechanical watches, especially for luxury timepieces.

Crystal

The type of crystal that the watch employs is mineral glass. Mineral glass is a glass-based substance. Nowadays, tempered mineral glass is used in almost all mineral glass timepieces. It means that the glass’s surface has been heat-hardened or heated to a high temperature, which makes it barely break or scratch.

Mineral glass is generally robust and resilient. However, it shatters rather than giving up in the event of a collision. If the mineral glass becomes scratched, it cannot be polished and must be replaced. However, it withstands everyday use quite well and requires a strong force to break.

Dial

Like any other Casio model with a classic style, this watch’s face allows you to easily read the time. Also, the digits are pretty clear, and the backlight is enough to see in the dark.

There are three buttons around the watch’s face. One is a button to turn on the light; another button used to enter the mode that changes the time or alarm is flat, so it is not accidentally pressed. And the last one is for setting the stopwatch. On the front face, the writing is pretty simplistic.

Strap/bracelet

Lots of customers have different opinions on the strap. Some people say that they like how down-to-earth the strap is, while others think it doesn’t give them a luxurious vibe. So if you want to look expensive yet classic, this timepiece might not be the best choice.

Regardless, almost all feedback from customers states that the strap is easily adjustable. So even if the watch is a bit loose or tight to you, it should be no problem wearing it.

Other special features

The primary time display is well-organized, easy to see, and includes a valid calendar for the rest of the century. Furthermore, the alarm can be set in various ways, and it is worthwhile to read the instructions. Timer and chronograph functions are similar to those found on other watches, with the added benefit of displaying the current time simultaneously.

Overall, this is a reasonably sized, well-designed watch with functions that most owners can use.
