From design to production.

As Outrider moves through prototyping, our original CAD is being translated into the engineering drawings and specifications the factory will use to manufacture each component.

This is where dimensions are finalised, tolerances are checked, and the details that turn a design into a physical watch are worked through.

A little look at some of the factory engineering work happening behind the scenes as Outrider gets closer to becoming a reality.

39 mm case. 45.5 mm lug-to-lug. 20 mm lug width. 7 mm screw-down crown.

REEF

Australia’s reefs are a landscape of their own. Shallow turquoise waters, shifting currents and darker formations beneath the surface.

Reef draws from those layers of colour and movement. The turquoise dial uses a flowing texture through the centre, while the fumé outer section deepens towards the edge, creating a sense of depth across the dial.

Reef completes the six Outrider colourways.

What do you think of the final addition to the collection?

AURORA

The Aurora Australis is one of the more elusive sights in Australia’s southern skies. When conditions align, the darkness comes alive with shifting displays of green, pink, red, violet and blue.

Aurora takes its inspiration from that contrast between the dark night sky and bursts of colour. The deep purple dial features a fine radial texture through the centre, surrounded by a fumé outer section that gradually darkens towards the edge.

In lower light it can appear dark and understated, while brighter light brings out a much richer, more vibrant purple.

COAST

Australia’s coastline can look completely different from one stretch to the next. Golden sand, pale dunes, weathered rock and clear blue-green water, all shaped by the same meeting of land and sea.

Coast takes its inspiration from those lighter, more natural tones. The warm off-white dial is paired with dark furniture for contrast, while the centre carries an organic texture inspired by patterns formed in sand by wind and water.

It’s a quieter colourway than some of the Outrider range, but perhaps the one that most captures the textures we wanted the collection to be about.

Australia’s interior is shaped by some of the oldest landscapes on Earth, with iron-rich earth, weathered rock and vast stretches of red defining much of the country’s centre. That unmistakable landscape became the starting point for Outback.

The dial combines a vivid red with an organic, flowing texture through the centre, drawing from the patterns formed across the land by wind and time. A darker outer section frames the texture and gives the red different character as the light moves across it.

Outback is our interpretation of Australia’s red centre: bold, warm and distinctly Australian.
