Casio Edifice EFS-S660D-1AEF
Product Information
This is the watch
The black, textured dial gathers the chronograph's three sub-dials, date display, and a blue central chronograph hand. The smaller dials display regular seconds, the chronograph's 1/20th of a second, and the chronograph's hours and minutes. Surrounding the dial is a tachymeter scale, used in conjunction with the stopwatch to calculate average speed. The analog design and motorsport focus give the model a sporty yet elegant character, while the central hand makes the chronograph measurement easy to follow.
Materials & fit
The case measures 45.3 mm in length, 38.3 mm in width, and 11.6 mm in height. The watch weighs 129 grams. Both the case and bracelet are made of stainless steel, and the bracelet closes with a one-handed triple-fold clasp. Casio specifies a wrist size of 150–205 mm. The dial is protected by sapphire crystal with an anti-reflective coating, which reduces distracting reflections when reading the information on the dial.
Highlights
- The solar power system is charged by light passing through the dial and has approximately five months of operating time from a full charge until the hands stop.
- The chronograph measures in 1/20th-second increments up to 59 minutes and 59.95 seconds, with modes for elapsed time, split time, and first and second place times.
- The tachymeter scale can be used to calculate average speed.
- Water resistance of 10 ATM is a level that allows for swimming.
Good to know
- Casio specifies an accuracy of ±20 seconds per month.
- A low battery warning indicates when the watch needs more light.
- The date is displayed in a separate window on the dial.
