Hands-On: The Citizen Eco-Drive Photon Keeps The Brand Ahead Of Their Light-Powered Competitors

A little over a month ago, Citizen celebrated the 50th anniversary of Eco-Drive with a massive bash in New York and a few new releases. The most striking, and unlike anything they had released in the past, was the new Photon. Aptly named, of course, because of the very particles—oh wait, or is it waves?—that power Eco-Drive movements. And before we get any further, these aren’t solar watches like most watch movements that could be considered a “competitor” on the market. They are powered by any light around you, whether it’s your office lights, home lights, or yes, the big bright ball in the sky that’s starting to peek out more and more in New York.

If you want to know more about Eco-Drive, our friend Griffin recently published a story about the technology (and its history) here. But this watch requires a slightly different history lesson. If you take a look at the dial below, you’ll see it has a very unusual design. It’s also out of the ordinary for Citizen, which prides itself on creating watches that can pass for any other watch aesthetically and don’t require slits in the dial to transmit light (a problem other brands have struggled to engineer around).

The new Citizen Eco-Drive Photons are two watches measuring 39.6mm by 9.9mm with integrated bracelets, all of which are made of Super Titanium with Duratect coating. One features a titanium carbide finish, while the other, with a two-tone dial and case band, uses a DLC finish. Each is limited to 5,000 pieces and available starting this fall for $995 (titanium carbide) or $1,195 (DLC). So you still have time to plan ahead if you like what you see.

As you can see, the case is one big draw, but the dial is hard to ignore. The dial uses a multi-layer construction that is meant to evoke the “double-slit experiment.” In short, that experiment, using two cuts in a surface and pointing a light source (like a laser) at it, shows that light creates an interference pattern and exhibits wave-like behavior. But they’re also a particle. As a commenter on our intro points out, Feynman believes they’re just a particle. Look, I’m no physicist. I can barely spell the word. But what I can talk about is the watch itself.

The brand is so good at its technology that they license it to other companies, like TAG Heuer. The dial starts with a ring (the dial cover) with luminous indices at 5-minute intervals and printed minute intervals, plus rounded dauphine hands, with the second hand coated in orange or purple/blue. 

The next layer is a metallic dial composed of three triangular layers, each nested within the other and converging at the center. Below that, another metal dial of concentric circles. Finally, a layer of structural color film filters the light. The effect results in a shifting pattern, one that almost seems to move as you look at it due to the moiré effect that gives an illusion of movement.

The watch, with its Super Titanium case, seems to lean more toward the tool-watch archetype based on material alone, but it offers only 50 meters of water resistance, and the lume, while present, isn’t particularly strong. Looking at the whole picture, you can see how it actually aligns with the use case for a Royal Oak or Nautilus, just at a much lower price point.

The watch features a solid caseback—unsurprising for an Eco-Drive watch with little to show inside—and will have the edition number on the caseback (out of 5000). The bracelet is structural but not too stiff, with a mix of brushed surfaces on the main structure and polished surfaces on the center links that hold it together.

On the wrist, the Photon is (unsurprisingly) comfortable. At first, I had a hard time believing that the watch (which was a non-working sample) actually had a movement inside. I checked with the brand, and it did, in fact, but because of the super titanium case and relatively lightweight movement (compared to an automatic movement in my other titanium divers), the watch was remarkably light. That did mean I wasn’t able to test the accuracy of the movement, but the new caliber E036 can run for one full year when fully charged, with the stated accuracy of ±15 seconds per month.

While the watch wasn’t perfectly sized to my wrist, you can see it fit quite well. Part of that was due to the built-in micro-adjust, which gave me a bit of extra flexibility. But there was no cheating here; no stuffing a glove behind the bracelet to make it fit tighter, hiding how it hung off the wrist. Just a comfortable watch on my 7.25″ wrist.

The last point that seemed to get people worked up was the design itself. I see the argument of similarities to the H. Moser Streamliner, but I don’t entirely agree. I mean, it looks more like a Streamliner than a Royal Oak or Nautilus, with a squared-off case, a round dial, and a sloping bracelet. But compare this to other recent offerings from other affordable brands (even Citizen themselves), and it’s far less derivative. Some brands have even gone so far as to make nearly one-for-one copies of a design made by the same designer for both watches. In that way, I think Citizen has done a great job, especially at a price of around $1,000.
