Oris introduces a technological beauty, a version of the ProPilot X Calibre 400 with a shimmering dial produced using an innovative lasering technique never applied in watchmaking before – Oris ProPilot X Calibre 400 Laser.

Going our own way

Independence is a gift. We use it to be more sustainable and more innovative, and to seek out technological beauty

At Oris, we’ve got a strong independent streak. We’re not publicly listed, which means we’re free to make our own choices and pursue ideas that make sense to us – and to our customers. That’s hard-wired into our psyche, and it’s what drives our sustainability, movement creation and design programmes.

In recent years, it’s led us to new collaborations. Often, that’s with highly visible partners in conservation or community action. Other times, it’s behind-the-scenes. We’re proud to work with some of Switzerland’s most pioneering ideas labs and engineering firms, pushing high-quality Swiss Made mechanical watches into the future.

This approach was behind the ProPilot Altimeter’s unique carbon-fibre case and the game-changing Calibre 400 Series of five-day automatic, anti-magnetic movements.

Always, these ideas are conceived and developed in-house by our teams of designers and engineers, who then oversee them right through to delivery. The partnerships we’ve developed have involved incredible knowledge sharing, and the watches we’ve been able to create because of them are loaded with innovation, useful functions and huge added value.

Now comes the ProPilot X Calibre 400 Laser, produced with a research lab affiliated to the prestigious ETH Zürich university. Our partnership gives some of the world’s brightest and most entrepreneurial students the opportunity to develop their ideas into real-world products.

The lasering process applied to the dial of the new watch elevates the benefits of this approach further still, bringing levels of technological beauty never seen in watchmaking before, as we’ll explain over the coming pages.

This unique way of working is only possible because of our independence. It’s who we are.

A dial like no other

The ProPilot X Calibre 400 Laser’s dial is produced using an innovative technique never seen before in Swiss mechanical watchmaking

It’s a pity we’re only working in two dimensions here. The titanium dial of the new Oris ProPilot X Calibre 400 Laser has to be seen to be appreciated. As it moves, it changes colour, from blue to green to violet, like the colouration in iridescent beetles.

Indeed, it’s based on the principles of biomimicry, specifically a phenomenon found in nature called optical interference. This means that red light waves are destroyed, while blue and green waves are reflected. It’s barely believable, but there is not one drop of colour pigment in this watch’s dial.

This inventive treatment is a surface manipulation that splits the light into its components, creating a stunning rainbow effect that changes depending on your viewing angle.

Everything on the dial has been created using laser technology. For the logo, indices, minutes track and dial text, we used another laser process that creates a three-dimensional effect, so that it almost looks as if these elements have been applied in the conventional style. The view through a loupe is spectacular.

The laser technique we used to create the dial’s unique colour is a watchmaking first. It was developed in partnership with a research lab affiliated to ETH Zürich and applied to the titanium dial under the guidance of our engineering department, led by Richard ‘Ipy’ Siegrist (see next page). It’s a fine example of technological beauty, harnessing state-of-the-art tech to create striking, memorable watches.

Beyond the dial, the watch carries the familiar, challenging form of the forward-looking ProPilot X Calibre 400, first introduced in 2022. It has a titanium 39 mm case, bezel and crown, and a three-link titanium bracelet.

Inside it is the mechanical Oris Calibre 400, our game-changing five-day automatic. It offers better-than-chronometer accuracy and class-leading levels of anti-magnetism and reliability, backed by a 10-year warranty and 10-year recommended service intervals. However, for the first time, we’ve removed the date, leaving the dial to tell its remarkable story.
