Casio’s First Automatic Sports Watch Is a Slick, Seiko-Powered Showstopper

If watchmaking was a simple matter of timekeeping accuracy, the people who make them could have stopped trying a long time ago.

Which is to say, the fact that Casio’s latest release is probably the least accurate watch across its vast, ever-expanding catalog should do little to dampen enthusiast intrigue.

That’s because the EFK-100D is Casio’s first automatic watch and one that promises to appeal to both die-hard Casio-heads and seasoned watch nerds that can recite movements on demand.

Making moves

Speaking of movements, Casio turned to Seiko to supply its dependable NH35A workhorse widely used across the industry, especially among microbrands to keep their prices competitive.

Of course, it pales in accuracy compared to Seiko’s other legendary calibers. However, the NH35A is reliable enough and gives the watch a 40-hour power reserve with a daily rate of -35 to +45 seconds.

Of course, accuracy can only get you so far and thankfully, there’s more to the EFK-100D than its guts — which, for the record, are showcased through an exhibition caseback.

Dialed in

The watch comes in four unique dial treatments, including a premium black carbon variant, with the other three treated with something called electroforming to resemble forged carbon.

All in all, the subtle texture gives the EFK-100D an air of subtle refinement, complemented by the mirrored bezel and brushed case and bracelet — both of which are stainless steel.

Availability and pricing

In the long run, how the EFK-100D is ultimately received will come down to the final asking price.

Casio has yet to reveal US figures, however, the watch starts at 49,500 Japanese yen, suggestive of something around $350.

Nonetheless, an automatic timepiece shows some spine from Casio to stretch beyond its various comfort zones, with the promise of much higher-end watches in the future.
