Product Description
The Casio Edifice EF527D-1AV is a pilot-style chronograph that fuses technical precision with a robust build, drawing influence from classic aviation instruments. Known among enthusiasts for its slide rule bezel and multi-dial layout, the EF527D-1AV offers professional-grade functionality at a highly accessible tier.
At its core is a quartz movement that drives a 1/20-second chronograph, capable of measuring elapsed time up to 12 hours. The inner rotating slide rule bezel operated via the crown at 8 o’clock enables a variety of aviation and engineering calculations, a rare inclusion in this price category. This technical element makes the watch especially popular among pilot watch fans and those who appreciate functional wristwear.
The stainless steel case measures 45.5mm in diameter and 11.4mm in thickness, giving it solid wrist presence without feeling overbuilt. It’s paired with a matching stainless steel bracelet, equipped with a double-locking fold-over clasp for secure wear. A black dial houses three sub-dials one each for 60-second, 60-minute, and 24-hour indicators while luminous hands and markers ensure visibility in low light.
Water-resistant up to 100 meters, the EF527D-1AV balances sport readiness with everyday versatility. Its mineral crystal adds a layer of durability, while the tachymeter and date display at 3 o’clock round out its utilitarian edge.
Often compared to higher-priced pilot chronographs, the Casio EF527D-1AV Edifice has earned a reputation as a value-driven timepiece that delivers technical aesthetics and function without compromise. Whether for aviation use or everyday wear, it’s a standout within the Edifice lineup.
