ORIS – Big Crown ProPilot Altimeter NEW
The new Oris Big Crown ProPilot Altimeter
More than 75 years after Oris made its first pilot’s watch, the company is proud to announce the launch of the most innovative pilot’s watch in its history – the Oris Big Crown ProPilot Altimeter, the world’s first automatic mechanical watch with a mechanical altimeter.
It’s the latest in a long line of Oris pilot’s watches, stretching back to 1938. Oris has a proud tradition of making accurate, reliable, industrially manufactured and sensibly priced wristwatches, which is why Oris has become the pilot’s choice.
The Oris Big Crown ProPilot Altimeter has been developed entirely by Oris to serve as a high-performance instrument for pilots.

The altimeter of the Oris Big Crown ProPilot
Altimeter is activated by unscrewing the crown into ‘Position 1’,
indicated by a red ring. Once set, the watch shows the current altitude
via a yellow indicator, and the corresponding air pressure via a red
indicator.
Watchmaking takes to the skies
The histories of watchmaking and aviation are inextricably linked. Developments in aviation during the first four decades of the
20th century had transformed the notion of heavier-than-air flight from an impossible dream into a commercial, industrial and military reality. Flying was the future – it was fast, exciting, dangerous, and the men and women who took to the skies became heroic figures.
Like the aircraft themselves, early navigational flying aids were very basic. It quickly became clear that pilots needed quality timekeeping instruments they could depend on when planning routes and manoeuvres, and undertaking airborne missions.

Pocket watches were still the trend during the early flight years at the beginning of the
20th century. But for pilots, who would be gloved to protect them from the elements, fumbling around in a pocket for an important reading was impractical.
The practical alternative was a watch worn on the wrist. No longer hidden from view, wristwatches meant pilots could quickly and easily reference the time without a great deal of movement. Wristwatches were quickly adopted by pilots around the world.

Accurate wristwatches played a vital role in the war effort. Here, US pilots synchronise their timepieces before take-off.
A period of innovation
But they weren’t perfect, and improvements followed. Movements became smaller, because few pilots could wear a pocket watch on their wrist without it being an obstruction in the confined space of a cockpit. Dials became more legible, stripped back to the essentials, with luminescent materials applied to the hands and hour markers so the watch could be read during night flying. And crowns became larger so pilots could operate a watch while wearing gloves.
As aircraft and the men and women who flew them became more and more popular, so the pilot’s watch aesthetic grew in influence. Those returning from wartime operations were heroes – and their standard-issue watches became symbols of their heroic deeds. Aviation made wristwatches both better and more fashionable.
The pilot’s choice
Oris was at the heart of this sea change. The original
1938 Big Crown Pointer Date watch
was pioneering, not just because of its oversized crown, but because of
its pointer date function, a design that would become the
Oris signature.
In
the decades since,
Oris has produced legion pilot’s watches. Over the
last 20 years, many have been produced in honour of
Oris partnerships;
others have been limited editions, created to mark significant landmarks
in aviation history or the achievements of contemporary pilots.

Produced in 1938, the Oris Pointer Date had a central hand indicating the date and an oversized crown. Today it has become th brand’s signature design.
The
Oris Flight Timer 1945 LE marked
60 years since the end of the
Second World War; the
Oris
Polly Vacher Limited Edition celebrated the remarkable British
aviatrix, who in
2003 became the first woman to fly solo around the
globe via the North and South Poles; and this year, the
Oris Royal
Flying Doctor Service Limited Edition embodies the company’s partnership
with the iconic Australian aeromedical service.

Mainstays of the
Oris aviation
collection include the
Big Crown (continuing the story started
76 years
ago), the
BC3 and the
BC4. The
BC3 was introduced in
1999 and is a
classic pilot’s watch, with a robust round case, and black or white
dials with simple, highly legible detailing. The
BC4 design first
appeared in
2008. Its design was based on high-functioning cockpit
instruments, and it came loaded with functionality – current models
carry chronographs, retrograde dates, regulator dials and a world timer
that shows three time zones simultaneously, one of which can be adjusted
forwards or backwards in one-hour jumps via plus and minus pushbuttons
on either side of the case. In
2009, the
BC4 won a prestigious
Red Dot
Design award.
The story continues…
Aviation
continues to play a significant role in the
Oris line-up. In
2014,
Oris
introduced the
Big Crown ProPilot collection, a series of mechanical
watches designed to cope with life in the cockpit. Initially, there were
three models – a date, a day/date, both with an enlarged font size, and
a chronograph. Now, the Swiss watch company is unveiling the most
complicated pilot’s watch it has ever made – the
Oris Big Crown ProPilot
Altimeter. The new watch is an innovation pioneered by
Oris in its Höl
stein factory, and the world’s first and patented automatic mechanical
watch with a mechanical altimeter.

It demonstrates
Oris’s exceptional watchmaking know-how and horological ambition, both
of which have been built up over
110 years of watchmaking history.

time and date. The second crown at 4 o’clock operates the altimeter.

The new Oris Big Crown ProPilot Altimeter
An instrument designed for altitude workers
The
Oris Big Crown ProPilot Altimeter
has been developed entirely by
Oris to serve as a high-performance
instrument for pilots, mountaineers, explorers and research scientists,
who work at altitude. Its sturdy 47mm multi-piece stainless steel case
houses an
Oris automatic movement, and a Swiss mechanical barometric
altimeter and barometer movement.
One of the biggest
challenges facing
Oris engineers was the design of the altimeter hand
itself. Making the altimeter mechanism small enough to fit inside a
wristwatch meant the hand had to be extremely lightweight, but stiff
enough to avoid tolerances and therefore inaccurate readings. The
solution was to create it from laminated carbon fibre, making the hand
seven times lighter, but 10 times stiffer than the average watch hand.

The Oris Big Crown ProPilot Altimeter is available in three different textile straps: grey, green and black. Here shown with the grey textile strap and feet scale.
Another challenge was how to protect the inner workings of the watch from moisture when the altimeter is activated.
Oris patented a new altimeter adjustment and venting crown, which prevents moisture from entering the watch using a membrane made of
PTFE, which creates a vapour barrier.
The above mentioned aspects are covered by an
Oris patent i.e. the multi-function adjustment venting crown, the co-axial layout of the watch and altimeter movements, including a skeletonised movement holder, and the carbon fibre altimeter hand.
How the patented Oris Big Crown ProPilot Altimeter works
The
Oris Big Crown ProPilot Altimeter has two crowns. The crown at 2 o’clock is a conventional crown to adjust the time and date, and to wind the watch as necessary (the automatic movement has a 38-hour power reserve).
A second screw-down crown at 4 o’clock operates the altimeter. When screwed down into ‘Position 0’, the altimeter is inactive and the watch is water-resistant to 10 bar. The altimeter is activated by unscrewing the crown into ‘Position 1’, indicated by a red ring.

The Oris Big Crown ProPilot Altimeter is also available with a metre scale. Alternatively, the timepiece can be equipped with a leather strap or a metal bracelet.
When the crown is pulled out into ‘
Position 2’, thealtimeter can be
calibrated. Once set, the watch shows the current altitude via the
yellow indicator, and the corresponding air pressure via the red
indicator. The altitude scale is around the outer dial ring; it can
measure altitude up to
15,000 feet or
4,500 metres (two models have been
produced, one with a scale in feet, one in metres). The air pressure
scale is recessed between the altimeter scale and the central dial. Once
the altimeter is no longer required, the crown can be returned to
Position 0 by screwing it down, resealing the watch case and ensuring it
is once again water-resistant to 10 bar.
