R.O.1 space®

The first Dutch watch in space.

T-0 — scroll for the report

The R.O.1 space® is no ordinary watch. It is an instrument that has proven its worth in the most extreme environment imaginable: space.

Precision

The movement

In spaceflight, precision is not a luxury — it is vital

The beating heart of the R.O.1 space® is the renowned Valjoux 7750. This calibre is modified in R.O. Watches’ own atelier to meet strict chronometer standards.

Of course, this mechanical precision work is protected by the patented R.O. Watches Shock-System®.

Carbon fibre

The weight

During a launch, every gram counts

That is why the case of the R.O.1 space® is made from high-tech carbon fibre. This material combines extreme lightness with unmatched strength and stability under large temperature swings.

This material choice brought the weight down from 140 to just 72 grams, without sacrificing robustness or reliability.

The Shock-System®

The ultimate guarantee of shock resistance

Launches and landings unleash immense vibrations and G-forces. To protect the delicate movement against this violence, the R.O.1 space® is equipped with Roland Oostwegel’s worldwide patented shock system.

It offers the ultimate guarantee of shock resistance; better protection for a mechanical movement does not currently exist.

Personalisation

Your own design

Your signature in space

Although developed for space, every R.O.1 space® can be tuned to your personal aesthetic.

You can choose from various dials, ranging from deep anthracite to bright silver-white, combined with hands in different colourways. The day and date display can also be customised in language (NL, DE, EN) and colour.

This way you create a unique instrument that carries your signature.

Limited and unlimited variants

Of the limited editions (gold, ceramic, steel and titanium) with a carbon fibre case, only 53 pieces per variant were made. The unlimited variants (black and white) have a steel or steel PVD case.

The number 53 is a tribute to André Kuipers, who was that age during his historic mission.

Experiences of André Kuipers

Two R.O.1 space® watches accompanied André Kuipers on his mission to the International Space Station. This is his story.

In space

During the space journey

On the International Space Station (ISS), time is more than a given; it is a crucial instrument. During my daily work, the R.O.1 space® quickly became indispensable. The Orbit-Time counter proved its value time and again, so I knew to the second when a new orbit around Earth began.

At the same time, the Mission-Time counter gave me an instant overview of the total duration of my mission; days and weeks slipped by on the dial.

Living in weightlessness brings unique challenges. Because floating meant I moved my arms less intensively than on Earth, I occasionally had to wind the watches by hand. A moment of interaction between human and mechanism.

The ultimate test

The true character of the R.O.1 space® showed itself during an emergency. When we received a warning of approaching space debris, we had to take our seats in the Soyuz capsule as a precaution.

While the digital displays of our official mission watches sometimes faltered due to radiation, the analogue perfection of my R.O.1 space® kept ticking undisturbed.

“It was self-evident for me to take these along.”

The return

The ultimate trial by fire

The return to Earth was the ultimate trial by fire. The brutal deceleration from 28,000 km/h to 900 km/h, G-forces up to 6G and unimaginable vibrations are an assault on both people and materials.

It is an experience you would not wish on anyone, but both I and the watches came through this ordeal with flying colours.

Special moments of the R.O.1 space® in space

6 October 2012

After the space journey

On 6 October 2012 I visited Roland’s atelier in Heerlen for a special moment: the Post Mission Inspection. Together we thoroughly analysed the two watches and signed the certificates of these unique “Special Editions”.

The results were nothing short of astonishing. Even after the extreme conditions in space, the movements performed better than many unused top watches.

The future of the space watches

I am often asked what will happen to these space watches now. One thing is certain: they will not go to the highest bidder. For now they remain in our possession.

Roland and I will brainstorm about the future at our leisure, but above all we enjoy the fact that together we have written a unique chapter of Dutch watchmaking history.
