One surefire way to design a great homage watch is to borrow bits and pieces from a collection of iconic influences with a common thread, creating a mosaic dedicated to a certain time period or genre, rather than a specific watch.

Héron nailed this exercise in 2023 with the Marinor dive watch, a well-balanced and enthusiast-pleasing ode to 1950s aquatic tool watches. After being out of stock for more than a year, the Quebecois watch brand unveils a new-and-improved version of its best-seller.

The Marinor II is streamlined in both size and appearance, with the most obvious visual update being the removal of Héron’s flying bird logo from the dial. It creates a cleaner look, more in tune with its influences.

Classic diver fans will spot those influences right away, but the Canadian watchmaker cites its sources on a detailed product page. The Marinor collection draws from 1950s examples of the Rolex Submariner, Omega Seamaster 300, and Blancpain Fifty Fathoms.

The second generation of the Marinor, developed by tinkering with the original design for over a year, is available in four dial colors with matching bezels topped with curved sapphire crystal inserts.

There are three fumé dials in the grayish Atlantic Blue, the teal Caribbean Blue and the minty Menthol Green. But the option that comes closest to its vintage inspiration is the black-and-gilt dial.

Only copy the best

Any successful artist or creative will tell you that you shouldn’t be afraid to copy others with restraint, but only copy the best. Héron did an excellent job of pulling notable features from each of those three horological icons listed above and stitching them together in harmony.

The curved sapphire bezel is from the Fifty Fathoms, and the steel bezel frame even features a similar coin-edge. Even the dive track, with numerals at 15, 30 and 45, is spot-on, except for a triangle at 12:00 instead of a diamond.

Rolex’s dash-dot-triangle hour track is so influential that it is the default for dive watches. Naturally, Héron used a customized version with a North Star icon replacing the triangle at 12:00. The surrounding discrete minutes track also comes courtesy of The Crown.

As for the hands, they are a loose interpretation of Omega’s Seamaster 300 set. The proportions are a bit different, and Héron added a beveled shape. Additionally, the lume dot on the seconds hand, which is either not there or at the tip on vintage Seamaster references, is closer to a Rolex lollipop.

The dial is topped with an AR-coated box sapphire crystal, offering more durability than vintage acrylic examples. The hour markers, hands and bezel track are all filled with a green-glowing Super-LumiNova that is stronger than the first generation.

The 39mm brushed stainless steel case has been slimmed down to 12mm and treated with a hardening process that the brand claims makes it 10 times more scratch-resistant than standard steel. Additionally, the matching three-link steel bracelet features a thinner clasp with a new tool-less micro-adjustment system.

The Marinor II runs on a dependable Miyota Caliber 9039 automatic movement, which beats at 4Hz and has a 42-hour power reserve. It is capped by a screw-in stainless steel caseback engraved with a profile of a salty old sea captain.

Availability and price

The Héron Marinor II is available now for preorder from Héron for $640, with orders shipping out in June 2026. In a nice touch by the brand, the watch comes in a compact decorative box that doubles as a travel case.
