Swatch x Blancpain Green Abyss

In 2023, Swatch and Blancpain surprised the watch world with their collaborative Bioceramic Scuba Fifty Fathoms collection — an accessible tribute to Blancpain’s iconic dive watch legacy. Since then, the series has seen several colorful releases, each inspired by different oceanic themes. Now, the collection expands with what might be its most distinctive model yet: the Green Abyss.

This new edition surfaces just in time for summer 2025, offering a striking green design with an added technical touch pulled straight from Blancpain’s deep-sea heritage.

A New Colorway with an Old-School Feature

The most eye-catching update here is the rich matte green bioceramic case, complemented by sandy beige and black elements. It’s a look that blends modern Swatch styling with vintage dive watch cues, designed to evoke the feeling of descending into unexplored depths.

But beyond the aesthetics, the Green Abyss introduces a historically significant feature: a water contact indicator at 6 o’clock. This small yet clever complication will change color if water enters the case — a nod to the version Blancpain used in its Mil-Spec models all the way back in 1954. It’s not just a cool visual detail; it connects this playful Swatch version directly to the tool-watch roots of the Fifty Fathoms.

Under the Surface: Movement and Caseback

Inside the Green Abyss beats the SISTEM51, Swatch’s proprietary automatic movement known for being fully machine-assembled and offering an impressive 90-hour power reserve. While it doesn’t aim to compete with Swiss haute horlogerie, SISTEM51 keeps things accurate, anti-magnetic (thanks to the Nivachron hairspring), and maintenance-free.

Flipping the watch over, you’ll find a colorful digital print on the transparent caseback — a Felimare picta nudibranch (a species of sea slug) resting against a seabed backdrop. It’s a fitting, vibrant homage to the biodiversity of the ocean, tying in the environmental awareness that’s been a consistent theme in this collection.

Designed to Be Worn, Not Just Collected

The case size is familiar to those who’ve followed the series — just over 42mm wide and around 14mm thick, with a comfortable wrist presence that wears better than the numbers suggest. It’s paired with a NATO-style strap made from recycled fishing nets, continuing Swatch’s push toward sustainability.

The unidirectional bezel features a black resin insert and is filled with Grade A Super-LumiNova for strong underwater visibility. Together, the build and finishing give the Green Abyss a slightly more toolish look than some of its more colorful siblings.

Final Thoughts

The Green Abyss blends storytelling, function, and fun in a way that Swatch has mastered in recent years. It’s not trying to be a hardcore dive watch — but with its heritage-inspired indicator and thoughtful caseback, it’s more than just a fashion piece. If you’ve been holding out on this collab series, this might be the most compelling entry yet.

Weather you’re picking it up as a summer daily or as a conversation piece, the Green Abyss is a strong contender in the growing Swatch x Blancpain universe.
