We at Clockfever were incredibly proud to have been among the first in Sweden and Scandinavia to handle the Oris ProPilot X Calibre 400 when it launched at Watches and Wonders in Geneva. We spent a full week with the watch in the blue colourway, and it was a genuine pleasure.
This was the moment the ProPilot X stepped up: a full-titanium pilot watch carrying Oris’s in-house Calibre 400 movement. Here are our impressions from time spent with it on the wrist.
A week on the wrist
After a week of daily wear it was clear that the ProPilot X is a standout from Oris. The classic cues of the standard ProPilot are all here, including the ribbed, turbine-style bezel that has become the model’s signature, but everything has been elevated a couple of levels, from the dial texture to the hands and especially the bracelet, which is something else entirely.
The thing you notice immediately is that the ProPilot X is built entirely from titanium. The lightness of a titanium watch transforms the wearing experience, and that goes double when the bracelet is made from the same material. Oris has managed to keep a robust, solid feel despite the low weight, which is a tricky balance to strike. A lot of that comes down to the bracelet design, which feels remarkably stable on the wrist.
It sits at the more expensive end of the Oris range, but you are getting a fully titanium watch with one of the most talked-about movements in the industry, so we still think it offers a lot for the money. As always, check current pricing with an Oris retailer, as it varies by market and over time.
The ProPilot X up close
We were lucky enough to have perfect weather during our week with the first Swedish ProPilot X. Below are some of our own photos and a few details that caught our eye when we looked closer.

The dial of the ProPilot X has a lovely texture, not perfectly smooth but finely speckled, so it reveals more the closer you look. The applied indices and logo give it a tasteful, premium feel despite all that surface detail.
The hands are beautifully brushed with a fine pattern visible up close, tying in neatly with the rest of the watch.

The full-titanium bracelet is robust and stable, with neatly screwed pins.
Most importantly, it is genuinely comfortable to wear all day.

The clasp on the ProPilot models is completely unique and one of the coolest on the market right now.
It is designed to mimic an aircraft seatbelt buckle, an idea Oris has pulled off while keeping the function simple and secure.

The caseback, like the bezel, features a turbine-shaped outer ring, an aviation reference that appears in three places across the watch in total. The Calibre 400 movement is on display here too, and it looks superb with its large rotor.
The watch launched in three colours: grey, blue, and a salmon, almost pink, shade. The grey was always likely to be the main, most classic option, blending beautifully with the natural tone of the titanium, though all three have their fans. See the photos below.



We tried the blue, and we were delighted with it. What we love is that Oris skipped the obvious black and white and instead offered these three more characterful colours.
The blue felt like the most anticipated of the trio. The grey suits the model superbly and melts into the natural titanium tone. Best of all, Oris kept working with more adventurous colours, including bringing back a pink watch, even if it is officially called Salmon.
Oris Calibre 400

Oris has long done excellent work with exhibition casebacks, and that has become even more rewarding since the arrival of the in-house Calibre 400, a movement with genuinely impressive performance.
The headline figure is the power reserve: a full five days. That is remarkable when many brands are still working to reach three. The Calibre 400 also brings strong anti-magnetic resistance and a recommended service interval of around ten years, backed by a ten-year warranty, which is a serious statement of confidence.

Final verdict
The Oris ProPilot X Calibre 400 was a landmark release for the brand and it still holds up. A featherweight yet solid titanium case and bracelet, a brilliantly engineered clasp, a textured dial that rewards close inspection, and a five-day in-house movement on display through the caseback add up to a watch that feels special every time you put it on. If you want a distinctive, high-spec titanium pilot watch with real character, the ProPilot X remains an easy one to recommend.
What is special about the Oris Calibre 400?
It is an in-house automatic movement with around five days (120 hours) of power reserve, strong anti-magnetic resistance, and a ten-year recommended service interval backed by a ten-year warranty.
Is the ProPilot X really all titanium?
Yes. Both the case and the bracelet are titanium, which makes the watch very light while still feeling robust and comfortable on the wrist.
What colours does the ProPilot X come in?
The Calibre 400 version launched in grey, blue, and a salmon (pink) dial, with grey being the most classic, titanium-matching choice.
