Comparison Casio G-Shock GW-M5610U-1B vs Casio G-Shock GW-M5610U-1E

The amount of time that the watch is able to operate normally without winding the spring or changing/recharging the battery (for more details, see "Power source"). Modern mechanical watches (see “Movement type”) have a standard power reserve of 40+/-5 hours. However, this parameter is usually indicated for the simplest mode of operation, without the use of additional functions such as a chronograph(see “Functions / Capabilities” ), which also “eat up” the plant. Thus, such a watch is supposed to be wound every day, but nothing will happen if you miss the usual time and remember to wind it a few hours later than usual.

In turn, for quartz watches, the power reserve is often not indicated in the specifications. This is due to the fact that this parameter, firstly, is quite large compared to mechanical models (it would be measured in tens of days rather than hours), and secondly, it strongly depends on a number of external factors (for example, the quality of the next batteries). Therefore, it is very difficult, if not impossible, to reliably determine the power reserve in such cases.

Clock face background colour. Indicated for models with pointer or combination dials (see "Dial type"); in purely electronic models, usually, either a grey substrate (for conventional LCDs) or a dark base (for LEDs) is used.

The most popular in modern watches are black, white, silver and blue dials. However, in addition to this, other shades can be found on the market — in particular, beige, yellow, green, golden, brown, red, orange, pink, grey and purple. A special case are watches with chameleon glasses (see below).

Some models are available in several colour options, in such cases these options are listed separated by commas — for example, "white, red, silver." If the dial is painted simultaneously in 2 or 3 colours, they are indicated as a combination — for example, "white with red" or "white with yellow and red". And multi-coloured models include models in which more than 3 colours are used for the dial.
