HELICON Master ULTRAMARINE x Master Diver, AMI

Helicon Master – One Year of Real-World Diving with Master Diver, Ami Helicon Watches, a small independent British brand, is proud to share an exclusive look at the Helicon Master after a full year of rigorous real-world testing. Unlike many brands that showcase only pristine,untouched timepieces, Helicon believe in true transparency—and there’s no better way to prove their watch’s capability than showing you one that has been in daily use, in the ocean, by a real diver. Meet Ami – Master Diver & Helicon Test Diver, Ami is no ordinary watch wearer. As a master diver, and lead researcher for the Seychelles Whale Shark Research Programme, she spends seven days a week working in one of the world’s most challenging yet breathtaking marine environments. Her role isn’t just about studying whale sharks—it involves overseeing dive safety,managing ecotourism programs, and advising local government and conservation partners. In these conditions, reliability is everything, and for the past year, Ami has relied on her Helicon Master – Ultramarine Edition, as her daily timekeeping tool.

One Year in the Ocean – No Cosmetic Refresh, No Gimmicks - Many brands would hesitate to show you a watch after a year of hard use, but Helicon believe in showing the real thing. Ami’s Helicon Master has endured: 

• Hundreds of hours underwater 

• Constant exposure to salt water, sun, and sand 

• Dives up to 60m deep • Daily wear—no babying, no desk diving 

Yet, after a year in one of the most demanding real-world environments, it’s still going strong. The 316L stainless steel case remains resilient, the bezel action is smooth and precise, and the SuperLumiNova dial still delivers outstanding legibility.

Inside, the automatic movement continues to run flawlessly, proving why Helicon chose this ultra-reliable caliber for their professional-grade dive watch. FKM Skin Diver Strap – Built for Comfort & Durability Ami’s daily life means constant exposure to salt water, strong sun, and extreme conditions.

While she primarily wears Helicon’s high-performance rubber dive strap, sometimes she needs a change—especially when her skin has been subjected to the elements. That’s why she also uses Helicon’s FKM Skin Diver strap, which provides: 

� Ultimate comfort after long hours in the water 

� Resistance to UV and salt exposure 

� A soft, flexible feel for all-day wear And just like the watch, after a year of wear, it still looks as good as new. 

Every Helicon Master Purchase Helps Support Whale Shark Conservation - Helicon Watches isn’t just about creating great dive instruments—they believe in supporting the people and causes that matter.

That’s why every purchase of a Helicon Master helps fund Ami’s ongoing conservation work, protecting one of the ocean’s most majestic species—the whale shark. In 2025,

Ami will continue her work tracking and monitoring whale sharks, managing sustainable ecotourism, and ensuring marine conservation remains a priority in the Seychelles and beyond. 

If you’re looking for a true dive instrument, tested in the ocean, by a real diver, this is it.

H2O Watch KALMAR 2 DEEP DIVER 25000M [unlocking the depths]

Brutalism is back baby! Hmm, perhaps it never went anywhere to start with. Panerai, Ulysses Nardin and to some extent even some of those more mainstream Swiss names like Omega, Oris and Rolex are still building big sturdy watches, watches for adventurers and explorers of the deep. Watches for hairy-chested, shark wrangling, bear-wrestling, monster-truck driving, muscle-car racing, beer drinking, meat-eating, red-blooded men - who just happen to have a keen eye for detail and more than a passing appreciation for technical engineering. But here's the thing I think a lot watch enthusiasts still misunderstand about diver's watches, they're supposed to be big, they're supposed to be bulky and why because diver's want highly legible dials to shine in the depths and they require solid build quality that can stand up to the rigors of the deep. When it comes to high legibility, scratch that, insane levels of legibility, and when it comes to tank-like and you can scratch that too, nuclear submarine-like case construction few do it better, none go deeper or burn quite as brightly, and for less than H2O Watch of Germany. For Spring 2025 the King of Customization, the Ruler of the Deep and the new Lord of Luminosity is back with a newly updated version of their record-breaking DEEP DIVER 25000M. Unfathomable levels of customization and water-resistance. The H2O Watch KALMAR 2 DEEP DIVER 25000M resurfaces from the depths owing to public demand and boasting H2O’s stunning NEW “porthole bezel”. An unfathomable level of customization. Customization is king, it's what sets H2O Watch apart from its contemporaries. It's what allows their loyal following of customers to create the perfect configuration every time they invest in one of our highly engineered creations, allowing them to become a part of the creative process. And it's why H2O Watch believe customization is everything! With the H2O Watch KALMAR 2 DEEP DIVER 25000M you can create your dream watch with a plethora of customization options. Interchangeable crown guards and bezels, closed or display case-backs, in addition to 21 different dials to choose from. And it doesn't stop there, case-finishing, straps and more allow for almost 1.5 million combinations that are yours for the taking. An unfathomable level of water-resistance. From the depth of design to the depth of emotion experienced when you wear one of their depth-defying creations on your wrist and gaze in awe at this marvel of modern dive-watch engineering. H2O Watch has become one of the most important names in extreme water-resistance. From the outset, they have strived to reach the plummeting depths of the ocean. From their humble beginnings in 2010 when we debuted our inaugural deep diver, the Kalmar, tested to 600 bars of pressure, the equivalent of 6000 meters under the sea. To their record-breaking H2O Watch KALMAR 2 DEEP DIVER 25000M which we are proud to announce is back by public demand and boasting even more customization than ever. The H2O Watch KALMAR 2 DEEP DIVER 25000M is the final word in mechanical watch water-resistance, not only leaving the competition floundering in the relative shallows. But smashing any pre-existing records by some considerable margin. Thus establishing the H2O Watch KALMAR 2 DEEP DIVER 25000M as the deepest mechanical diver's watch to have ever been produced both commercially or as an experimental project. The H2O KALMAR 2 DEEP DIVER 25000M was tested and officially certified by an established German institute to withstand a pressure of more than 2500 bar.

ZRC MN64 HETERIUM [dive watch of distinction]

A new era of ZRC diver’s watches has begun! Last year was year was significant year for ZRC who celebrated their 120th Anniversary, propelling themselves into a new era of discovery with the release of the PHÉNIX in addition to the launch a new model line based on the SECURICODE from 1960s. For 2025 ZRC continue to improve and update their flagship MN64 collection which now boasts several new references, including a NEW Titanium model and this beauty! Introducing ZRC’s NEW range-topping diver’s model, the ZRC MN64 HETERIUM, based on their iconic diver’s watch, developed for the French Navy in 1964. But ZRC say of the new HETERIUM that it is more than a diver's watch, rather a multi-purpose watch that's just as at home in extreme conditions as it is in everyday life. Its elegant design and cutting-edge engineering should make it an ideal choice for adventurers, divers and lovers of luxury watchmaking. Its gradient dial, from navy blue to black, recalls the wild beauty of the ocean, while its 41.5 mm case in 316L in anti-magnetic Stainless steel bears witness to its robustness and refinement. Equipped with the elaborate Swiss Automatic SELLITA SW300-1 movement, the HETERIUM offers a precision of +/- 5 seconds per day and a 56-hour power reserve. Its specially engineered deformation case-back system allows for and impressive water-resistant to 1000 metres, tested to 1500 meters. The HETERIUM is available in 2 versions, with a choice of a black rubber strap (GF421618) or a metal ‘Diver’ bracelet (GF421613).

AQUASTAR Airstar Chronograph 60th anniversary Re-Edition STEEL [versatility is its middle name]

Introducing the NEW Aquastar Airstar Chronograph 60th anniversary Re-Edition in Stainless steel, the pilot’s watch that likes to get wet! While the Airstar with its classic syringe-style hands, tachymetric scale and bidirectional timing bezel allude to the model’s true designation as that of a pilot’s watch. It’s features like its old school skindiver case, water-resistance to 200 meters and screw-down case-back and crown that make it one of the more versatile models in Aquastar’s modern-day lineup. And while the Airstar is indeed a proud pilot, it was produced by Aquastar, a company largely focused on nautical watches, specifically diver’s and regatta watches, those made as traditional tool-watches. Like the ones that accompanied some of the diving and horological industries’ most celebrated divers and aquanauts, Jacques Mayol and Phillipe Cousteau to name but a few. So it is not surprising that the Airstar’s design and build was heavily influenced by and ultimately benefited from the kind of robust construction techniques employed in the world of traditional Swiss diver’s watches. Much like any other modern-day Aquastar model reimagined from their catalog of models, gleaned from their historic archives, it is an almost perfect one-for-one likeness safe for the inclusion of the most up-to-date watchmaking materials and perhaps a tweak here and there in its dimensions. Thus offering the wearer a truly authentic experience along with the peace of mind that only comes from wearing a contemporary tool watch. While the original Airstar’s 38mm in diameter case housed the venerable Valjoux 72, its modern-day successor, the Airstar Re-edition in Stainless steel’s 39mm skindiver case is home to a reliable Valjoux 7753 automatic mechanical movement. And just like any other pilot’s watch, the Airstar is destined for the skies but will likely take to the seas like a duck takes to water. Perhaps as few as just 200 examples of the vintage Airstar were produced. Likewise today’s Airstar STEEL has been produced in a Limited Run of only 300 pieces. The Airstar Black Edition is already SOLD OUT. The NEW Aquastar Airstar Chronograph 60th anniversary Re-Edition in Stainless steel is available for PRE-ORDER now. Please follow the link for more on the Airstar and other models from Aquastar.

A few words from Aquastar: “Among many of the innovations pioneered by Aquastar founder Frederic Robert, the Airstar Chronograph from 1964 was a departure from the traditional tool dive watch” says Rick Marei, Aquastar’s modern helmsman. 

“The Airstar features a depth rating of 200 meters, a screw down crown and many attributes essential for serious water resistance, yet combined with aviation grade capabilities”.
