Casio Edifice – Solar-Powered Chronograph with Sapphire Crystal

The Casio Edifice EFS-S510D-1A is a versatile men’s watch designed for both everyday wear and sports activities, combining refined style with practical functionality.

Its transparent black dial features a date display at 3 o’clock, a 24-hour sub-dial, and a chronograph capable of measuring up to 30 minutes. Timing is controlled via the side pushers—top to start/stop, bottom to reset—while the sub-dials track minutes and seconds with precision.

Constructed from stainless steel, the 46 mm case and matching bracelet offer durability and presence on the wrist. The sapphire crystal provides excellent scratch resistance, and the luminous hands and indices ensure legibility in low light. With 100 m water resistance, the watch is suitable for swimming and other water activities.

Powered by solar technology, the EFS-S510D-1A recharges from natural or artificial light, eliminating the need for frequent battery replacements and offering a longer lifespan than conventional quartz models.
