Aquastar Deepstar II Polarstar Limited Edition
The Aquastar Deepstar II Polarstar is a Limited Edition of the Deepstar II Swiss automatic wrist watch with no-decompression bezel and panda dial layout.
Presenting a highly sought-after variant of the Deepstar II line, which marries this handsome white sunburst dial with the signature Deepstar aesthetic in a pared-back three-hand format: hours, minutes, and small seconds.
Complete with a running seconds indicator at 9:00 in our distinctive “cyclops” totalizer, it retains the unmistakable design language of the Deepstar line, just as founder Frederic Robert might have once envisioned it.
Indeed, the Deepstar II ‘Polarstar’ is just what many Aquastar fans have been asking for, and like the other limited editions that have preceded this one, we fully expect this Deepstar II to sell out in short order, so we’d highly recommend a prompt reservation to guarantee yours.

DEEPSTAR II, UNMISTAKABLY AN AQUASTAR
Where Original Design Meets Modern Mastery
AQUASTAR DEEPSTAR II
The Second Gen Deepstar operates using the same bezel patent for multiple dives
Defining the Diver’s Watch Legacy
Like its predecessor from 2020, the new Deepstar II reflects a fully modern vision of the Aquastar brand, and its enigmatic, innovative founder who shaped a pivotal moment in mechanical watch history. This moment in timekeeping history represented a conscious shift from wrist watches as time-telling devices, to purpose-built tools designed for very specific fields, like diving and exploration. Aquastar didn’t invent the dive watch, but the brand crystallized its purpose in a singular vision, influencing an entire industry with category-defining innovations.

La Deepstar II Polarstar Limited Edition a dépassé mes attentes. Les finitions sont excellentes, le cadran est magnifique et très lisible, et la montre possède un caractère vintage unique tout en restant très moderne au poignet. Elle est extrêmement confortable grâce à ses dimensions contenues et ses proportions équilibrées. La lunette est précise et la qualité de fabrication inspire confiance. On sent que chaque détail a été particulièrement soigné. C'est une montre qui procure un vrai plaisir à chaque fois que je la porte. Je la recommande vivement à tous ceux qui apprécient les montres de plongée originales avec un véritable héritage.
★★★★★
This is my fourth Aquastar and to be honest my favorite. Simply because of its presence on my 7” wrist and contrasting black and white dial. I literally have 5 different straps and bands dedicated to this watch. Perfect size and dial design to make it my favorite Aquastar. So fortunate to have secured mine.
★★★★★
Years later, this is still one of my favorites to pull out of the watch box. The pink dial is truly a summer classic. Definitely will remain part of my permanent collection.

What a gem! The Deepstar ll just oozes fun, summer and adventure, along with anything else you can hope for, from a reimaged brilliant model like this. as someone who truly appreciates the golden age of watchmaking, and the brilliance of simpler, yet robust and beautiful designs that were more about pushing boundaries, taking risks, and going forward (both design and technical wise) - the Deepstar ll is simply perfect - It’s that model that wasn't part of the old catalog but the one that truly belong there according to minds of Rick and the team and Marc Jasinski himself. It's a true compact and comfortable tank on the wrist with a ton of character and energy embedded in it. The build quality and finishing are truly great for the price point, with close attention to detail, both from the perspective of period-corrected details and technical decisions that have been made by the team. I truly recommend it to anyone who appreciates something that can feel both like a time machine from a different era with its unapologetic charm and character in a modern package. Packaging is beautiful as well. Needless to say, it would be truly great to put a tropic strap on it like they used to back then ;).
Questions
Before you order.
What is the Deepstar II?
The Deepstar II is described as 'the Deepstar that could have been back in 1967', an imagined successor to the original that strips out the chronograph complication while retaining the iconic Deepstar case shape, the patented decompression bezel, and the signature mono sub-dial. It is a 3-hand dive watch at 37mm, making it one of the most wearable watches in the lineup.
How does the sub-dial work without a chronograph?
In the Deepstar II, the distinctive cyclops-style mono sub-dial at 9:00 now houses the running seconds indicator rather than a chronograph counter. This preserves the immediately recognizable Deepstar visual identity while simplifying the mechanics to a reliable 3-hand automatic movement.
What color variants are available for the Deepstar II?
The Deepstar II is available in Blue Ray, Steel Grey, Vintage Black, a limited Silverstar edition (silver sunburst dial), a limited Greenwich edition (green sunburst dial), and a limited Polarstar edition (white sunburst dial). The non-BOR versions are on Seatbelt NATO or Tropic straps, and BOR bracelet variants are also offered.
What is the Deepstar II Polarstar?
The Polarstar is a limited-edition variant of the Deepstar II featuring a striking white sunburst dial, combined with the standard Deepstar asymmetric case design. It maintains the time-only 3-hand format with the running seconds at 9:00.
Is every Deepstar II individually numbered?
Yes. Each Deepstar II is numbered and engraved on the case back.
How often does the Deepstar II need servicing, and what does it cost?
A full service every 5 to 10 years is plenty, depending on how often you wear and dive it. There is no annual service requirement. It runs a Swiss automatic movement built for reliability and easy long-term maintenance. For a current service quote, reach us through the Aquastar service page.
How water resistant is the Deepstar II?
It is rated to 200 metres (20 ATM) with a screw-down crown, so it is a genuine dive watch, not a desk diver. Ample for recreational scuba diving, snorkelling, swimming and everyday wear.
How does the bezel work, and can I use it underwater with gloves?
It carries Aquastar's no-decompression bezel, the first and only dive bezel that lets you plan and track repetitive no-decompression dives directly from the wrist, not just a single descent. It turns firmly and grips cleanly even with thick neoprene diving gloves, in or out of the water.
Is the Deepstar II comfortable on a smaller wrist?
Very. At 37mm it is one of the most wearable watches in the Aquastar lineup, sitting neatly on slimmer wrists while keeping its vintage dive-watch character. A genuinely versatile, unisex size.
