Héron’s Marinor MkII: A Montréal Diver That Masters the Details
From a pandemic-born idea to a standout Canadian microbrand, Héron refines its craft until perfection is achieved.

Héron emerged from Montréal in 2021, one of the many ventures that began during the pandemic’s quieter times. Unlike many startups that faded as normalcy returned, Héron thrived. The founders embraced a neo-vintage aesthetic, pairing it with modern materials. This successful blend has allowed Héron to open a physical showroom in Montréal and expand its team — a notable achievement in the competitive microbrand market.
Héron offers a compelling proposition: create watches with the charm of vintage pieces but the durability for everyday wear. This means using hardness-coated stainless steel, sapphire crystals, and reliable Miyota automatic movements, all sold directly to consumers. The brand’s journey reflects a commitment to listening and evolving — starting with the Gladiateur, a dress-diver hybrid, before finding its stride with the Marinor dive watch. The Marinor’s popularity, including collaborations and limited editions, has been instrumental in funding the showroom and team growth.
When it was time to update the Marinor, Héron took nearly a year to refine it — demonstrating a deep understanding of its brand identity and a refusal to rush what matters.
The Marinor MkII
The Marinor MkII is Héron’s flagship model. It retains the compact 39mm case but enhances wearability in every measurable way: lug-to-lug distance is reduced from 47mm to 46mm, and thickness is trimmed from 12.9mm to 12.2mm with the boxed sapphire crystal — just 10.6mm without. The case, now rated to 250m of water resistance, is crafted from 1200HV hardness-coated steel, a considered trade-off that delivers a slimmer, more comfortable diver.
Attention to detail is evident throughout. A domed sapphire crystal covers the 120-click unidirectional lumed bezel. The caseback features an engraved captain, and the crown displays a ship’s wheel and north-star logo — small touches that speak to a brand with genuine character. The MkII dial is cleaner and brighter, available in five color options including a playful Menthol Green and a Rainbow variant with a vintage-inspired sandwich dial construction.

The redesigned flat-link steel bracelet is slimmer, coated for hardness, and includes a push-and-glide micro-adjust clasp with screwed links and quick-release spring bars — the kind of bracelet refinement that elevates a watch from good to genuinely great on the wrist.
Also New: The Mirabel GMT
For those seeking a dressier complication, Héron’s new Mirabel GMT brings a GMT function to four colorways — Cigar Club, White, Brown, and Blue — priced at USD $690. It rounds out a lineup that now speaks confidently to both dive watch enthusiasts and the travel-minded collector.
Héron sells directly through its official website, and visitors to Montréal can explore the full collection in person at the brand’s showroom. For a microbrand that began during a pandemic, the trajectory is nothing short of remarkable.
Why this watch, on this wrist?
