The Casio Edifice ECB-2000D-1A is a solar-powered analog-digital watch with a stainless-steel bracelet, Bluetooth smartphone linking and a design motif drawn from formula-car suspension. The motorsport connection is an inspiration for its four-arm lug arrangement—not evidence that the watch was used or tested by racing teams. Here are the exact model’s materials, dimensions and functions, as listed by Casio.
What makes the ECB-2000D-1A race-car inspired?
Casio says the ECB-2000 line’s four-arm lug arrangement takes its motif from formula-car suspension. The lugs are the structures that connect the case to the band, so the inspiration appears in the watch’s case design rather than in a claim about racing performance. Casio also describes the line as the first EDIFICE with a carbon-fibre-reinforced resin case; for the D-1A specifically, its product listing identifies the case and bezel as carbon and stainless steel. Casio’s official ECB-2000D-1A product page is the source for both the design description and the model specifications.

ECB-2000D-1A specifications
| Specification | Casio listing |
|---|---|
| Case and bezel | Carbon / stainless steel |
| Band | Stainless steel, one-touch 3-fold clasp |
| Dimensions (length × width × height) | 51 × 47.8 × 10.8 mm |

These are manufacturer specifications, not independent measurements. The D-1A’s stainless-steel band and carbon/stainless-steel case and bezel identify this variant; do not assume another ECB-2000 reference has the same materials or finish.
Solar power and estimated runtime
Casio estimates approximately seven months of operation after a full charge with normal use and no further light exposure. Its estimate rises to approximately 18 months when the watch is kept in total darkness with power saving enabled after a full charge. These are conditional manufacturer estimates, not independent battery-life test results. The watch uses Tough Solar power.

Bluetooth and phone-linked features
When linked through the CASIO WATCHES app, the ECB-2000D-1A can use automatic time adjustment, settings, app-based world time, stopwatch-data transfer, Time & Place and phone finder. Casio lists the app’s world-time selection as approximately 300 cities. Phone compatibility depends on the device and software; check Casio’s current guidance for a specific phone before relying on these functions.
Timing, alarms and display functions
- Stopwatch: measures to 1/100 second and stores up to 200 laps. Lap data can transfer to a smartphone, where Casio says times can be displayed to the millisecond.
- Countdown timer: included for timed intervals.
- Daily alarms: five.
- World time on the watch: 38 cities plus UTC. This is distinct from the approximately 300-city selection in the app.
- Visibility and hand control: double LED Super Illuminator and a hand-shift feature.
- Phone finder: a linked-phone convenience function.
Water resistance and practical ownership details
Casio rates the ECB-2000D-1A at 10 bar (100 metres on its product page). That rating is the manufacturer’s specification; it should not be expanded into a promise about a particular activity without activity-specific guidance from Casio.
