Comparison Casio Edifice EQB-510D-1A vs Casio Edifice EQB-500D-1A

A function found in quartz watches (see "Movement type") with an arrow dial. In fact, End Of Life is an indicator that signals a critically low battery. It works as follows: when the charge is running out, the second hand begins to “jump” immediately through 2 or 4 divisions, moving not once a second, but once every 2 or 4 seconds, respectively. Such a warning is clearly visible to the user, and the slow movement of the arrow additionally saves battery power, increasing the time to find and replace the battery.

The nominal size of a watch case in diameter (for round cases) or width (for other options, see "Case Shape"). In the most miniature modern models, this size is 21 – 25 mm or even less, among the largest there are cases of 46 – 50 mm and even larger.

Larger watches are more convenient in the sense that the dial readings are better visible on them, and it is easier to provide various additional functions in the design. On the other hand, small watches look neater and create less discomfort directly when worn. In addition, female models (see "Gender") are traditionally made more miniature than male ones. So the choice for this indicator depends mainly on the intended specifics of the application: for example, large cases are best suited for outdoor activities and tourism, about 41 – 45 mm in size, for household wear (regardless of gender) — about 31 – 35 mm, and as an accessory to an evening dress, a small watch of 30 mm or less would be more appropriate.

Also note that the size of a compatible strap/bracelet is associated with this indicator — see "Strap Width" for details.
