Update Gruvebus Green: 2025 delivery sold out. Pre-orders for the 2026 delivery are now open.
Deep inside the Arctic archipelago of Svalbard, Norwegian miners have worked seams of ultra-pure anthracite for over a century. Gruvebus takes its name—and its toughness—from that legacy.
Quenched mining-grade steel – the 40 mm case is fired with high-carbon anthracite from Svalbard’s Mine 7, then salt-quenched, boosting hardness from about 192 HV to 224 HV (≈ 17 % harder than standard 316 L) for better scratch and impact resistance.
Always-on glow – Swiss Trigalight GTLS tubes in the hands and hour markers emit a steady green-blue light for 25 years, backed up by a burst of Swiss Super-LumiNova when you step from sun to shaft.
Coal-textured dial – an exact 3D impression of raw coal is pressed into the brass dial, sealed under three layers of clear lacquer so it feels smooth but looks rugged.
Case-back tribute – a deep relief of the load-bearing miner from Longyearbyen’s iconic Gruvebus statue—reproduced with permission from sculptor Tore Bjørn Skjølsvik—honours the men and women who move mountains underground.
Only 175 pieces of the green dial will ever be made – each with an individually numbered caseback. A unique piece of Arctic industrial history – captured in a timepiece.

We are a Norwegian watch brand that was started in 2017 by three Norwegian watch enthusiasts.
For us, Norway is defined in many ways by the presence or absence of light in spectacular nature. Many of our dials and designs are therefore inspired by the many and unique lighting conditions you can experience above the arctic circle, and we allow ourselves to be fascinated by how these in their own way create an experience of time.
We combine quality components and design in watches that we hope will be with you for a long time to come. Our goal is to make watches in quality materials at an unbeatable price that have a finish normally only found in higher price ranges. We design and do all the development in Norway, while the production takes place abroad. We only source high-quality components and can mention, among other things, surgical grade stainless steel and scratch-resistant sapphire glass with anti-reflection coating on the inside. Miyota, Seiko or Sellita movements respectively from Japan or Switzerland. Swiss Super-LumiNova® and full-grain leather from Italy or Horween leather from Chicago in the USA.
The Gruvebus watch is an Arctic monument in time-piece form, engineered to withstand the very darkness that inspired it. Swiss GTLS tritium tubes in the hands and hour markers emit a constant glow, while Swiss Super-LumiNova bursts to life when you move from light to shadow.
The dial bears a pattern taken from a coal fragment we found in Mine 3—an exact impression pressed into the plate to capture the raw texture of the bedrock beneath Longyearbyen—then sealed under three layers of clear lacquer to give a perfectly smooth surface for the markers and luminous tubes
The caseback carries a deep relief depicting an interpretation of the Gruvebus statue in Longyearbyen – reproduced with permission from the artist Tore Bjørn Skjølsvik – as a tribute to the miners who shaped the town. Each model is individually numbered and produced in strictly limited quantities: 350 pieces with a black dial, 300 with white, and only 175 with blue and green dials.
At its core beats an swiss automatic Sellita SW200 movement, ensuring reliable precision.
Arctic anthracite is sought after for its ultra-low sulphur, high energy output and near-pure carbon content. Its steady, oxygen-lean flame is perfect for steelmaking, casting moulds and any application that needs scale-free heat and a clean finish.
For the Gruvebus watch we fire our forge with coal from Mine 7—up to 98 % fixed carbon, the same fuel that chemical giant Clariant has trusted for four decades in premium pigments and automotive catalysts. We use it in both the casting moulds and the forge itself. The stable, low-oxygen flame lets us heat 316 L steel to about 870 °C without creating surface scale, then snap-quench it in a salt bath. Hardness climbs from roughly 192 HV to 224 HV—about 17 % harder—delivering noticeably better scratch and impact resistance than ordinary 316 L stainless steel.

The Gruvebus is powered by the Swiss automatic Sellita SW200-1 calibre. Beating at 28,800 vibrations per hour (4 Hz), it delivers a smooth, exact seconds sweep. Twenty-six jewels reduce friction, while a power reserve of up to 41 hours keeps the watch running even when it’s off the wrist.
Between the sporty cases, dials inspired by cutting-edge scientific technology and great value, there’s a lot to fall in love with here.

"The Gruvebus may be tied to coal, but it is closer to eye candy with its shimmering dial with an integrated bracelet that is well crafted and beautifully finished this is a watch that will be a daily feature on my wrist!"
"Received mine a week and a half ago and haven't been able to rotate it out. Love the look, the feel, and the lume is amazing! I have many watches at various price points, this is worth every penny!"
"Beautiful watch, intend to keep in display case & wear in rotation w/ rest of automatic divers as uneven light grey watch face caught my eye, then checked out rest of AIGI GRUVEBUS specs."
"Like color, bracelet, feel - the whole experience. Hope in the future you’ll consider a larger watch face. All good. Thanks!"
"Beautiful and very high quality watch. Its my go-to for daily wear. I love everything about it."
"The watch is an absolute stunner! Love the dial, the size and everything about it. It would have been perfect if the paper work that usually comes with watches (especially limited edition) would have been complete - there was no card"
"Classic style, executed in a unique way that makes it stand out among all others. Simply wonderful, the images online do not show this watches true beauty. Based on some of the company photos, do not expect a matte green. The dial and bezel in its forest green is the superior of the color choices available for this watch! The dial color shifts in the light, altering from dark (forest) to light (almost metallic lime) on the Norwegian bedrock stamped surface - catching the eye, providing a unique experience throught the day's changing light and angle observed. Bezel rotation is crisp and gratifying. The combination of tritium tubes and super LumiNova have been criticized in some reviews I have seen. I, however, am proud to say it is executed to perfection - in fact - it is an additional selling point that drew me to its design. Thank you Aigi for making this design choice! The tritium hour markers catch the distortion of the raised saphire crystal and are a joy to see in the dark. Teardrop hour markers paired with the tear drop second hand are also excellent - a unique touch I have yet to find on any other watch. Details like these have drawn admiring attention from other watch enthusiasts I have encountered. The bracelet and clasp provide perfect fit and feel. The alternating brush and polish is classy but not overly bold. This bracelet brilliantly elevates this watch beyond others. On the fly adjustment is quick and easy whenever needed. My brothers and I are the proud owners of 3 of the 175 green Gruvebus. It is safe to say - we made the right decision; classic and timeless style, steeped in unique purposeful design - reflecting its and our Norwegian heritage."
