Our review
The Edifice EF-527D-1AVEF is a Casio chronograph with a black dial on a steel bracelet, in a 45 mm case. It is a sporty, busy-looking watch with a decent water rating and a battery that runs for years. The catches are its large size and a look that is more fashion than function.
What it is
Edifice is Casio's line of smart-looking metal sports watches, aimed at drivers and people who like a technical style. The EF-527D is a three-sub-dial chronograph with a black dial and steel bracelet. It sits between the plastic G-Shocks and the dressier Casio models.
The EF-527D is a long-running reference in the Edifice range, which gives it a good record of availability of spares and straps.
The movement
It is a quartz chronograph powered by a battery, with a stopwatch function and a date window. Quartz accuracy is better than any mechanical watch, within about 20 seconds a month. There is no solar charging, so a battery change is needed every few years. The chronograph subdials track elapsed time, and the layout is easy to learn.
Chronograph hands sometimes need resetting to zero after a shock or a battery change. This is a documented procedure in the manual and takes a few minutes. The stopwatch is useful for timing events up to a certain limit; check the listing for the maximum.
On the wrist
The case is about 45 mm across, so it is large and can look chunky on slim wrists. It is made of steel with a bezel that gives it a technical feel. The steel bracelet is reasonably solid, with a folding clasp. It is a heavier watch than the resin models in the catalogue.
The bracelet is a good length for most wrists but can be fiddly to resize without proper pins, so a jeweller may be needed. The black dial with white subdials gives good contrast.
Water and everyday wear
Casio lists a 100 m rating for this style, which allows swimming; check the listing to confirm. The crystal is mineral glass. Hands carry lume. Chronograph pushers should not be pressed under water. It is robust enough for everyday use.
Because it is quartz, there is no winding to worry about, and the watch is shock resistant enough for ordinary knocks, but not designed to survive abuse in the way a G-Shock is.
Against the alternatives
The Casio Edifice EFR-539D-1A2VUEF and Casio Edifice EFR-552D-1AVUEF are similar chronographs with different dials. The Bulova Lunar Pilot 96B258 is a premium quartz chronograph. The Seiko Prospex Speedtimer SSC915P1 is a solar one. The Sekonda Velocity Chronograph 45mm is a more affordable British brand alternative.
For people who want a bit of a motorsport feel, the busy dial layout is the main attraction.
Who it's for, and who should skip it
It suits someone who wants a sporty steel chronograph without paying much and does not mind a big case. Skip it if you want solar power, a small case or a dressy look.
If you like the idea of a robust, no-nonsense daily watch with a dressier look than a G-Shock, it fits well, but look elsewhere if you want a refined finish.
