Edifice Chronograph 100M Quartz

The Casio Edifice EFV-640D-2BV is a new men's wristwatch with a stainless steel case and bracelet. Blue dial markers and a date window sit beneath mineral crystal. Quartz calibre 5345 drives the analog chronograph display. Water resistance is rated to 100 metres.

Suited For Daily Wear Not Deep Dive

This watch suits buyers wanting a stainless steel chronograph for everyday use and recreational swimming. The 44.30 mm case thickness and fixed bezel may feel bulky on smaller wrists. It is not for buyers who need ISO-rated dive timing or a screw-down crown.

Quartz Calibre 5345 Movement

The single specification that decides fit is the quartz calibre 5345 movement. It delivers battery-powered chronograph function without manual winding. Buyers who prefer mechanical automatic movements should look at a different watch.

Questions about this item

How often will the quartz movement in the EFV-640D-2BV need a battery replacement?

The quartz movement powered by Caliber 5345 typically requires a battery change every two to three years depending on chronograph use.

What is the first limit reached when the chronograph runs continuously on this watch?

Continuous chronograph operation draws more current from the battery, so the power reserve is the first limit reached under sustained use.

Does the stainless steel case and mineral crystal of the EFV-640D-2BV become noticeably warm during all-day wear?

The quartz Caliber 5345 produces negligible heat and the 44.30 mm stainless steel case stays at skin temperature during all-day wear.
