Most watch complications tell you about elapsed time — a chronograph, a GMT, a countdown bezel. The Sinn 308 Hunting Watch tells you something else entirely: how much natural moonlight you'll actually have to see by. Unveiled at Watches & Wonders Geneva 2026, it's a stripped-down, 40 mm take on Sinn's existing Hunting Watch chronograph (known in German as the Jagduhr), built around a single, genuinely unusual feature — a moonlight display calibrated for people working outdoors after dark.
It's a smaller, simpler, three-hand version of that original concept, and arguably the more interesting watch for it. Here's a full breakdown of what the 308 is, what the moonlight display actually does, what it costs, and who it's realistically for.

What Is the Sinn 308 Hunting Watch?
Sinn already made a Hunting Watch — a chronograph with an olive dial, a pointer date, and a moon-phase-style display, aimed squarely at the outdoor and hunting crowd. The 308 takes that core idea and simplifies it: no chronograph, no sub-dials, a more wrist-friendly 40 mm case, and a clean three-hand layout built around the one feature that actually matters for the use case. It sits apart from Sinn's EZM mission-timer watches, which are designed for professional operators; the 308 is aimed more at hikers, hunters, and outdoor enthusiasts who want genuine functionality without a tool-watch-sized case.
The Moonlight Display: What It Actually Does
This is the reason the 308 exists. At 6 o'clock sits what Sinn calls a moonlight display — visually similar to a conventional moon-phase complication, but functionally different. Rather than just tracking the lunar cycle for its own sake, it's calibrated to show when natural moonlight is bright enough to see by outdoors, without artificial light. That matters in contexts — hunting among them — where using a flashlight or headlamp isn't practical or permitted, and the only light available is whatever the moon provides.
Both the moonlight display and the hour markers use hybrid-ceramic luminous elements, applied by hand, which Sinn says delivers notably strong luminous intensity and legibility after dark — the one condition this watch is explicitly designed around.
Design and Dial
The dial is a deep, dark green — a clear departure from the black dials of Sinn's EZM line, and a deliberate nod to the outdoor, hunting-adjacent character of the watch. A centre-mounted pointer date hand keeps the layout clean rather than adding a date window that would interrupt the dial. Combined with the 40 mm case, the overall effect reads closer to a refined field watch than a rugged instrument piece — distinct from most of Sinn's catalog, where oversized cases and tool-watch proportions are the norm.
Notably, the 308 skips a rotating bezel entirely. Where most Sinn watches — including the EZM series — build around a bezel as a core functional element, the 308 keeps the bezel-free dial as the whole story, reinforcing that this watch is built around one complication rather than several.
Case, Build Quality, and Water Resistance
The case is 40 mm across and 12 mm thick, in satin-finished stainless steel, with a sapphire crystal up front, anti-reflective coated on both sides. Unlike many Sinn tool watches with solid casebacks, the 308 uses a transparent sapphire case back — also anti-reflective on the interior — so the Sellita movement is visible, which is a clear signal this watch is positioned closer to an everyday, display-worthy piece than a purely utilitarian tool.
Water resistance is rated to 20 bar (200 m) to DIN 8310, with a screw-down crown and case back. Sinn also specifically notes the case is low-pressure resistant — relevant for anyone taking it into the mountains, where reduced atmospheric pressure at altitude can be a real engineering consideration that pure dive-watch pressure ratings don't always account for.
Movement: Sellita SW382-1
Power comes from a Sellita SW382-1, a self-winding movement with 25 jewels, running at 28,800 vph (4 Hz), with a stop-seconds (hacking) function and an estimated power reserve of around 56 hours.
It's modified to drive the moonlight display and pointer date, and meets DIN 8309 anti-magnetic resistance — a solid, well-regarded workhorse base rather than an exotic in-house caliber, consistent with how Sinn typically allocates engineering budget toward case and functional features over movement decoration.
Ar-Dehumidifying Technology
The 308 carries Sinn's Ar-Dehumidifying Technology, a drying-capsule system built into the case that reduces internal humidity and helps prevent the crystal from fogging and the movement from corroding when the watch moves between temperatures and environments — exactly the kind of swing you'd expect from a dawn-to-dusk day outdoors.
It's the same underlying technology family found across much of Sinn's tool-watch lineup, here applied to a watch built for weather exposure rather than depth.
Straps, Bracelet, and Pricing
The 308 Hunting Watch costs around $3,340 on a nubuck wild boar leather strap, with a notably broad range of options for a Sinn tool watch: leather, metal (steel bracelet), silicone, textile, and Alcantara, plus alligator leather upgrades at an additional cost. When configured on Sinn's satin-finished solid stainless steel bracelet, the price rises to $3,770.
Pricing is set by Sinn in euros and will vary once converted and marked up through dealers outside Europe, so it's worth confirming current regional pricing directly with Sinn or an authorized dealer before buying.
Who Is the Sinn 308 Hunting Watch For?
Hunters and outdoor enthusiasts who actually use a moonlight gauge. This isn't a decorative moon-phase complication — it's built around a specific, practical use case, and it's most valuable to people who genuinely operate outdoors after dark.
Sinn fans who want something smaller and more wearable than the EZM lineup. At 40 mm and 12 mm thick, with a dressier dial and display case back, the 308 is a noticeably easier daily wear than most of Sinn's professional tool watches.
Buyers who want a distinctive story without an oversized case. Few watches at this price do anything as specific as the 308's moonlight display.
Less of a fit if you want a rotating bezel, a chronograph, or the maximum-robustness feel of Sinn's EZM watches — the 308 trades some of that ruggedness for a more refined, everyday-wearable package.
Sinn 308 vs. the 3006 Chronograph
The line between a purpose-built tool watch and a complex mechanical display is where Sinn operates best, and nowhere is that focus clearer than in their Jagduhr (hunting watch) lineage. While both the Sinn 308 and the Jagduhr 3006 share a specialized heritage designed around German hunting laws—where artificial lights are forbidden at night, requiring hunters to rely on ambient moonlight ("Sauensonne")—the two timepieces approach this functional brief with fundamentally different mechanical scope and wrist presence.
The Sinn 3006 Chronograph is the maximalist, heavy-duty origin point for the brand’s modern hunting display. Measuring a substantial 44 mm in diameter and 15.5 mm thick, it combines a full chronograph (powered by a Concepto movement) with a triple calendar and a 24-hour day/night indicator alongside its signature moonlight display. Built as an uncompromising piece of gear, the 3006 features a fully TEGIMENT-hardened, satinized stainless steel case, Ar-Dehumidifying Technology, D3-System pushers, and 200 meters of water resistance. It packs virtually every high-spec technology in Frankfurt's arsenal into a sprawling, olive-green dial layout engineered for maximum utility.
In contrast, the Sinn 308 distills the hunting concept down to a leaner, everyday-wearable layout. Stripping away the chronograph pushers, sub-dials, and triple-calendar windows, the 308 isolates the core functions: hours, minutes, central sweep seconds, a pointer date, and the moonlight display at 6 o'clock. By shifting to a Sellita SW382-1 architecture, Sinn reduced the case dimensions to a versatile 40 mm diameter with a slim 12 mm profile. While it omits the TEGIMENT case hardening of the 3006, it retains the 20 bar water resistance, sapphire crystal, Ar-Dehumidifying capsule, and high-contrast hybrid-ceramic luminous elements on the dark green dial.
Ultimately, the choice between the two comes down to whether you prefer a feature-packed wrist instrument or a refined daily field watch. The 3006 remains a tactical flex—a massive, ultra-hardened chronograph built for those who want the full suite of mechanical tracking complications on the wrist. The 308 offers the exact same specialized lunar utility in a cleaner, significantly lighter package that wears like a traditional three-hander while retaining Sinn's signature Teutonic durability.
Verdict
The Sinn 308 Hunting Watch is a rare case of a niche complication that's actually built for its stated purpose rather than existing as a conversation piece. The moonlight display is genuinely functional, the 40 mm case solves the main wearability complaint against Sinn's larger tool watches, and the display case back and expanded strap options signal a brand comfortable letting a watch be good-looking as well as purposeful. It won't appeal to buyers who want a rotating bezel or chronograph, and the Sellita SW382-1 inside is a sensible rather than exciting choice of movement — but as a distinctive outdoor watch with real substance behind its headline feature, the 308 is one of the more quietly compelling releases in Sinn's current lineup.
