When Swatch and Blancpain first unveiled their joint take on the Fifty Fathoms back in 2023, the watch world was stunned. One of the most iconic dive watches of all time, made accessible to the masses through Swatch’s innovative Bioceramic material and SISTEM51 automatic movement? That was a big deal. The launch proved wildly successful, and it wasn’t long before collectors — serious horologists and casual fans alike — were clamoring to get their hands on each new variant.
Fast forward nearly two years, and Swatch has released a total of eight different Bioceramic Scuba Fifty Fathoms models, each inspired by a different ocean and featuring its own unique sea creature. They’ve ranged from the playful and colorful to the quietly sophisticated. But the ninth release, coming June 7th, takes a very different approach — one that leans less into marine tropics and more into military grit.
Enter the Swatch x Blancpain Bioceramic Scuba Fifty Fathoms Green Abyss — a name that hints at darkness, depth, and something a little more serious than your average beach-ready diver. With a muted olive-green colorway and tan accents, it’s a watch that trades the coral reef for combat boots — and in doing so, it might just be the most compelling version yet.
Tactical Elegance: A Colorway with History
While most previous entries in the collection embraced oceanic themes and bright hues — think deep blues, turquoise, sunset orange — the Green Abyss is notably subdued. Its earthy color palette isn’t merely a stylistic shift; it’s steeped in symbolism and historical weight.
The main shade, officially dubbed “Green Abyss” by Swatch, is unmistakably Olive Drab (OD) Green — a tone synonymous with military uniforms, gear, and utilitarian function. From 1952 through 1989, OD Green was the standard color for U.S. military utility uniforms across all branches. It was a color born of pragmatism: easy to manufacture, easy to blend in with the environment, and hard to forget.
Its use in this diver is a nod to those years of service history — not in a heavy-handed way, but in a way that will resonate with military buffs and style purists alike. Alongside this, the watch features field tan accents on the dial markers, hands, bezel detailing, and strap stitching — a classic pairing that’s often seen on field gear, backpacks, boots, and other tactical essentials.
It’s rare to see this kind of colorway on a diver, a genre of watch typically dominated by nautical blues, high-visibility oranges, or sleek monochromes. And that’s what makes the Green Abyss so fascinating: it bridges the gap between two worlds — the deep sea and the battlefield — in a way that feels effortless.
Function Meets Style: Familiar Framework, Fresh Identity
In terms of construction, the Green Abyss maintains the same DNA that made the rest of the Fifty Fathoms collaboration such a sensation. The case and bezel are crafted from Swatch’s proprietary Bioceramic material, a composite made from two-thirds ceramic and one-third castor oil-derived bio-sourced plastic. The result? A watch that’s ultra-lightweight, surprisingly durable, and undeniably unique in hand.
The 42.3mm case wears comfortably on most wrists, and the domed crystal gives it just the right vintage feel. The matte green Bioceramic case lends a tactile softness to the touch, yet remains tough enough to handle everyday knocks.
The real showpiece — quite literally — is on the back. Like its predecessors, the Green Abyss features an exhibition caseback that displays the whimsical, ocean-themed artwork Swatch has made a trademark of this collection. In this case, a nudibranch (a type of sea slug) glides playfully across the transparent back, as if patrolling its own underwater battlefield. It’s a reminder that, while this model may look military, it hasn’t forgotten its aquatic roots.
Beneath the artwork lies the engine powering the watch: the SISTEM51 automatic movement. Assembled entirely by machines, this revolutionary movement consists of just 51 components, held together by a single central screw. It offers an impressive 90-hour power reserve, meaning you can wear it Friday through Sunday — or leave it off for a few days — without worrying about it stopping.
Eco-Conscious Construction
Continuing a theme from previous models, the Green Abyss comes fitted with a two-piece NATO-style strap made from recycled fishing nets — a move that speaks to the watch’s sustainable ethos. It’s fitted with a Bioceramic buckle and loops, ensuring visual harmony with the case.
Swatch’s decision to use marine waste for the strap is more than a design gimmick. It’s a subtle nod to Blancpain’s longstanding commitment to ocean preservation — from its support of scientific expeditions to its funding of marine biodiversity documentaries.
Not Just a Watch — A Statement
The Green Abyss is priced at $400 USD, staying true to the accessible luxury spirit that defines the collaboration. That’s right: a Swiss-made, automatic dive watch — with a storied name like Blancpain on the dial — for under $500. Even with the one-per-customer policy that will accompany the in-store launch, demand is expected to be fierce.
While some purists may scoff at the Swatchified version of the Fifty Fathoms, others see this series as an entry point — a way for younger collectors or budget-conscious enthusiasts to participate in the high-end world of Swiss horology. With its military-inspired look, the Green Abyss also opens the door to new audiences: tactical gear fans, field watch collectors, and even veterans looking for something with a personal connection.
The Verdict
So, is the Green Abyss the best version of the Swatch x Blancpain Scuba Fifty Fathoms yet? That’s always going to be a matter of taste. But in terms of sheer design cohesion, cultural resonance, and wearable versatility, it’s hard to argue against it.
This watch isn’t just about diving, and it’s not just about fashion. It’s about storytelling — of service, of utility, of innovation, and yes, of style. It’s the kind of piece that can spark a conversation or quietly complement an outfit, depending on how you wear it.
Whether you’re a seasoned collector or someone who’s just been waiting for the right Fifty Fathoms to come along, the Green Abyss is worth a closer look.
Just don’t wait too long — come June 7th, you might find yourself in line behind a dozen others who already know what this watch represents.
