Earthen Summit MKII: Ceramic Field Watch with Secret Glow

It’s not every day you see a salmon dial. It’s even rarer to see one that glows entirely in the dark. For $899, Earthen Company is offering exactly that, wrapped in a crisp white ceramic case with dimensions that look just about perfect on paper. The watch is the Summit Dawn Til Dusk MKII, an update to Earthen’s popular field watch platform. It’s part of a growing trend of microbrands and independents delivering serious material science and thoughtful design at a price that challenges the big players. This isn’t just another steel sports watch; it’s a purpose-built piece with a very distinct personality. Earthen Company has built a reputation for its nature-inspired designs and adventurous spirit. The Summit collection is their take on the modern field watch, blending rugged specs with clean, contemporary aesthetics. The Dawn Til Dusk MKII feels like the most confident expression of that idea yet.

The Earthen Company Summit Dawn Til Dusk MKII

The name “Dawn Til Dusk” isn’t just marketing copy; it’s the core concept of this watch. It’s designed to have two distinct characters. One for the day, and another for the night, perfectly capturing the changing light of a long day spent outdoors.

The Case: Ceramic and Compact

Let's start with the case material, because it’s a big part of the value here. The Summit uses a pristine white ceramic. Ceramic is incredibly difficult to work with, which is why it’s usually found on watches costing many thousands of dollars. Its key benefit is extreme scratch resistance. We’re talking a Vickers hardness number that leaves even hardened stainless steel in the dust. This means the case should look brand new for years, shrugging off the daily scrapes and bumps that would scar a metal watch. The dimensions are what really sell it for everyday wear. A 38mm diameter is a modern sweet spot that works for a huge range of wrists. The lug-to-lug is a compact 45mm, which is crucial for preventing overhang on smaller wrists. At just 10mm thick (and only 8.8mm if you don’t count the crystal), this watch should slide under a cuff with no problem. Earthen Company has given the familiar Summit silhouette more definition with beveled edges, but it retains a clean, lightweight character. Finishing it off is an oversized, screw-down crown that’s easy to grip, even with gloves on. This, along with a solid caseback, helps secure a very practical 100 meters of water resistance. That's more than enough for swimming, hiking, and any adventure you’d throw at a field watch.

The Dial: A Split Personality

This is where the magic happens. In daylight, the dial is a soft, warm salmon-orange color. It’s a classic, handsome look that has been associated with high-end watchmaking for decades. Here, Earthen gives it a modern, casual spin. The layout is a clean, inverted 3-6-9 explorer-style dial, a small update for the MKII platform. The printing for the indices is multi-layered and deep, which should give the dial some welcome texture and dimensionality. But the real show starts when the lights go down. The entire dial surface is coated in a custom-developed lume. Unlike typical watches where only the hands and markers glow, the whole face of the Dawn Til Dusk comes alive with a vivid orange light. This isn't just a gimmick; it creates an incredibly legible display in total darkness. Creating a colored, full-lume dial is technically challenging. The luminescent compound has to be perfectly mixed and applied to achieve a consistent color in both light and dark conditions. That Earthen Company developed this in-house for a sub-$1000 watch is impressive. Protecting that special dial is a flat sapphire crystal. Crucially, it has anti-reflective coating on both sides. Dual-sided AR makes a huge difference in clarity, making the crystal practically disappear at certain angles and reducing glare significantly.

The Movement: A Solid Workhorse

Inside the Summit MKII is the Miyota 9039 automatic movement. For watch nerds, this is a very welcome sight. The 9-series is Miyota’s premium line, a direct competitor to Swiss movements like the ETA 2824 and Sellita SW200. The 9039 is a "no-date" caliber. This is a smart choice, as it means there’s no phantom crown position for a date wheel that doesn’t exist, keeping the operation clean and simple. It beats at a modern 28,800 vibrations per hour (4Hz), which gives the seconds hand a smooth sweep. Power reserve is quoted at 42 hours. While not class-leading in an era of 70+ hour movements, it’s a reliable standard. It means you can take the watch off Friday evening and it should still be running Monday morning, provided it was fully wound. Ultimately, the Miyota 9039 is a thin, reliable, and highly serviceable movement. It's the right choice for a watch like this, allowing Earthen Company to focus the budget on the expensive case and dial production while ensuring rock-solid timekeeping.

Straps and Value

The watch comes with two included straps, which is another nice touch. Both are made from FKM rubber, a high-grade fluoroelastomer that’s softer, more durable, and more resistant to oils and chemicals than standard silicone. You get one in a vibrant orange that matches the dial’s glow and another in a contrasting baby blue. This gives you two very different looks right out of the box. The 20mm lug width also means you’ll have a nearly infinite number of third-party strap options. The Earthen Company Summit Dawn Til Dusk MKII is a compelling package. It combines high-tech materials and a truly unique dial concept with classic, wearable proportions. It’s a watch that clearly knows what it wants to be: a fun, durable, and distinctive companion for any adventure. For a pre-order price of $899, delivering at the end of August, it represents a strong value proposition in a crowded market. If you’re tired of the endless parade of steel divers and want something with a bit more color and character, this one is absolutely worth a look.
