Kiwame Tokyo Iwao Sumi: A Japanese field watch that's too stylish to be in the mud

Japanese micro brand Kiwame Tokyo presents the Iwao Sumi. It's a field watch that blurs the line between tool and art with its 38mm diameter and rock-like dial texture. With a Miyota automatic movement and a price tag of under $700, it's a watch that seriously challenges established European competitors.

There's a neighborhood in Tokyo called Asakusa. It's a place where time moves a little slower. While the rest of the city is hurtling toward a cyber future, in Asakusa, artisans are still quietly and deliberately preserving tradition. And that's where it's at home. Kiwame Tokyo.

Founder of the brand, Masami Watanabe, is not a newcomer. The man has been importing luxury European watches for three decades Japan. He must have seen enough of the Swiss marketing gimmicks to say, “Enough. I can do this better.” And he did. His first models sold out faster than you can say “grand seiko.” Now he’s back with the Iwao Sumi, which is technically a field watch, but would be a sin to wear while digging trenches.

When the rock becomes a dial

The word “Iwao” means “massive rock” in Japanese. And it’s not just a poetic name that the marketing department slaps on the box. It’s the basis of the entire design.

The center of the dial has an embossed texture that actually resembles the rough surface of a stone. This gives the watch a depth that is rarely seen in this price range. However, the Japanese wouldn't be Japanese if they didn't counter this with something completely smooth. The rough center is surrounded by a satin ring, on which polished Arabic and baton indexes rest.

It's a play of light and shadow. The diamond-cut indexes catch the light with every movement of the wrist, while the textured background "swallows" reflections. The result? A watch that's legible but never boring.

Details you only notice with time

Most people expect a field watch to be boring. Army green and simple numbers. But Kiwame took a different approach.

The most interesting detail is the red-tipped seconds hand. Its shape is no coincidence; it mimics the roofline of the famous Kaminarimon gate in Asakusa. It’s the kind of subtle reference you love because it doesn’t scream “look at me,” but is only noticed by those who know where to look.

In addition, the designers used an interesting visual trick. The inner rim of the case (rehaut) is extremely low, and the minute scale is tilted. This gives the impression that the dial is floating just below the sapphire crystal. These are architectural details usually found in watches with a four-digit price tag.

Dimensions for the real world

Today, when watches seem to be getting bigger again, Kiwame remains sensible. The stainless steel case measures 38 millimeters. This is the “golden mean” for almost any wrist.

Even more important is the thickness – or lack thereof. The watch is just 9.5 millimeters thick. This means it will easily slip under a shirt, but it is also robust enough not to feel fragile. The lug-to-lug distance is 46 mm, which ensures a comfortable fit.

Despite its elegance, the case offers 100 meters of water resistance. The crown is not screw-down, but for most urban adventures and the occasional swim, this is more than enough.

Japanese engine under the hood

You won't find a Swiss movement inside the watch, and that's a good thing. The watch is powered by the Miyota 9039.

For those of you who aren’t watch geeks: this is the “premium” series from the Japanese manufacturer Citizen. The movement operates at 4 Hz (28,800 vibrations per hour), which ensures a smooth glide of the seconds hand. It has a 42-hour power reserve and, most importantly, it is a “no-date” movement. This means it doesn’t have a “phantom” position for the date on the crown, a detail that we purists greatly appreciate. It is reliable, thin and cheaper to service than its European cousins.

Price and availability

Kiwame Tokyo Iwao Sumi will be available from December 25th onwardse. Price? $690.

In a world where big brands charge thousands for basic models with plastic movement parts, this is a refreshingly fair deal. You get sapphire crystal with anti-reflective coating, excellent case finish, a reliable automatic movement, and a leather strap made from Italian calfskin.

If you're looking for a watch that has a story, looks more expensive than it is, and isn't another Rolex copy, this might be the best buy right now.
