CASIO EDIFICE ECB-2000D-1ADF SOSPENSIONE MEN WATCH

How does Tough Solar work, and how long does it run?

The watch charges from light through the dial and stores that charge internally, so normal daily wear keeps it topped up and there is no routine battery replacement. Note what it is not: this is light charging, with no winding or shaking involved — wrist movement does nothing for it, unlike an automatic mechanical watch. From a full charge it runs approximately seven months in normal use without further light, or around 18 months left in the dark with power saving active. How quickly it recharges depends on the light it gets. The rechargeable cell has a finite service life over many years, and replacing it is a service-centre job.

Why has the display gone blank?

That is the power saving function doing its job. When the watch is left in the dark, the display switches off to conserve charge while timekeeping carries on underneath. Move it into the light or press a button and the display returns with the correct time. Nothing is lost and no reset is needed.

What does the phone connection add?

It pairs with the free CASIO WATCHES app and corrects the time automatically four times a day, which is the main benefit — no adjustment when you travel or when a time zone shifts. The app also opens up around 300 world time cities against the 38 zones held on the watch, makes the settings easier to change on a screen than through the buttons, logs time and place, and can ring your phone to help you find it. Left unsynced, the watch holds ±15 seconds per month on its own.

How good is the stopwatch for timing laps?

It measures to 1/100 of a second for the first 60 minutes, then in 1-second units, with elapsed, lap and split timing. The part that matters at a track day is the memory: it holds 200 laps, and the app transfers them to your phone afterwards, so you can review a full session rather than scribbling times between runs.

What is the dial at 9 o'clock, and why does the minute hand move in steps?

That dial counts down to your next alarm or to the end of a running timer, giving you the remaining time as a glance at a hand rather than a number to read. It beeps 30 minutes ahead as a warning, and the timer and alarms have the same progress beeper. The minute hand advances every 20 seconds rather than sweeping, which is normal for this movement and conserves charge; running seconds appear digitally. A hand shift feature swings both hands clear of the digital window when you need to read it unobstructed.

What is the carbon case, and how does 10.8mm wear?

The case is carbon fibre-reinforced resin — the first EDIFICE built this way — with the four-arm lug layout drawn from race-car suspension, also carbon-reinforced. The practical result is the one you notice on the wrist: a 51 × 47.8mm watch carrying solar charging, Bluetooth and two LED systems at 10.8mm thick and 125 grams. It is wide, so it reads as a substantial watch from above, but slim enough to sit under a cuff rather than fight it.

Will it fit my wrist, and can I swim with it?

Casio lists a compatible band size of 150mm to 205mm. The bracelet is sized by removing links, which can be done in store at City Chain, and it closes on a one-touch three-fold clasp. As for water, 100-metre (10 BAR) resistance covers swimming, snorkelling and showering. It is not a diving watch — the rating is a laboratory pressure measurement, not a depth you should swim to — so avoid scuba diving and do not press the buttons while the watch is wet.

What warranty does this watch come with?

The ECB-2000D-1ADF comes with Casio's official 1-year warranty when purchased from City Chain Singapore, an authorised Casio retailer.
