Device of a French Army
Compass capsule concealed inside a pocket watch case. The
watch is only a mock-up made of a dial and hands soldered inside the
crystal frame but without any clock mechanism. The hands can't rotate.
The crown rotates freely. It's only a push-button giving way to the
compass visible under the snap lid.
The compass is stuck inside a
wooden frame. Its owner had the lid engraved —probably after
war— with his name and the number of the Stalag*
he had been
emprisoned. If it was made inside a camp, the maker must have
had access a good workshop.
* German abbrev. for Stammlager
i.e. prisoners camp for soldiers and petty officers

, the Department 9 of
the British Directorate of
Military Intelligence (M.I.9 - Escaped British Prisoners of War/POW,
Debriefing, Escape and Evasion) developed a great number of secret
means to conceal tools and instruments in harmless looking objects for
everyday use. The means the pilots carried with them during the air
raid were called pre-capture
These comprised many items like uniforms or shoes, that could easily be
converted in civilian plain clothes but also see saws, food, etc. This
department also sent to the POW's in the Offizierslager
About one in 5 parcel contained such materiel concealed in
tooth-brushes, pencils, playing cards, etc. The "empty" ones were

were several types of
escape compasses used by British Airmen to help them to escape capture,
and to aid POW's ‘on the run’. They were just one
of many in the escape packs issued by the Sqd Intelligence Officer
before each raid. (left: an early WWII RAF escape ration and survival
pack containing a compass. Because of the value attached to them
(especially the money packs), they were collected on the crew members
return. They also had to be up-dated with light-weight maps printed on
silk for the relevant mission areas (right: map of France and Italy,
FI). They apparently were issued to Army Special Forces as well.

The different types of escape compasses could be:
1. A small compass (in one piece) that was concealed in the hollow-out
heel of a flying boot (see picture 1).
2. One that formed the bottom half of a standard RAF Brass Button for a
no. 1 uniform (see note).
This button had a screw top with a reverse thread (i.e. unscrewed by
turning clockwise - see picture 2).
There were several manufacturers of these buttons: B'Ham Buttons Ltd.,
FIRMIN and J. R. Gaunt. The first one used smaller compasses which left
a space between the rim and the compass.
Nowadays, many fakes are being offered, BEWARE!
3. A compass consisting of 2 trouser fly buttons: the lower one had a
pivot and the upper one was magnetised.
4. A button made of bakelite with a magnetic element in it.
5. A compass concealed in the belt buckle.
6. A razor blade type used by sailors of the Royal Navy.
7. The magnetised tags of the flying
NOTE: The R.A.F. No. 1 (Home Dress) uniform was for parades and smart
occasions; it comprised a belted jacket with brass buttons for breast
and patch pockets, and a brass buckle for the belt. Strangely, this was
used by both bomber and fighter air crews in the early part of the war.
It was later replaced by battledress (No. 2 dress) that had a waisted
jacket that buttoned on to the back of the trousers, and had black
plastic buttons. The escape compass for battledress was hidden in 2
buttons (i.e. it had no crystal); one for the base and pivot, and the
other had the needle. Airmen and aircrew serving in hot climates had KD
uniforms with black buttons and belts. No. 5 Dress was the Mess Kit.

This razor blade was a magnetic needle. It had to be laid on the
surface of a liquid (like water in a glass) and would then turn around
so that the War Department arrows pointed north. Date : World War Two

When India became independent in 1947 the Royal Indian Artillery was
split with one part becoming the Royal Pakistan Artillery (RPA) which
lasted until 1956 when Pakistan became a republic and dropped the

Blouse Buckle Compass
The above mentioned website THE PARACHUTIST writes about this device:
"Early RAF uniform blouses used a toothed buckle for securing the belt
section on the bottom of the blouse. (...) The buckle was made of a
non-ferrous metal. The compass element was an arrow shaped piece of
magnetized material concealed on the back portion of the buckle. The
compass pivot was staked on a small swivel joint and when not in use
was folded flat against a cross bar. The compass portion was stored on
the opposite side of the same cross bar. A slider mounted on the same
cross bar retains both the pivot pin and the compass needle assembly.
To use as a compass, the slider is moved to release the compass element
and the pivots swung to a vertical position. The buckle is placed on a
stable horizontal surface and the compass needle assembly placed on the
pivot. The pointed end of the compass points toward the North Magnetic

grandfather gave me
these before he died in 1990. He was in the 8th
Army Air Force in 1944. He said he kept them between his toes. I'm
pretty sure he said they were tiny compasses. They have a needle pivot

This could be a compass case like the one displayed above

KONG EVACUATION AFTER THE JAPS
ATTACKED IN 1941 - JUST A HOAX?
the Japanese attacked Hong Kong in 1941, the pilots of
National Aviation Corporation
made many flying trips back and
forth, evacuating refugees from HK to the safety of Chongqing. One of
the pilots, Captain Hugh Chen, was obliged to make his evacuation in a
derelict old Vultee that was scarcely airworthy and had been stripped
of most of its instrumentation. After he took off, the few remaining
instruments ceased to function, but even though it was dark and he was
helpless, it was too dangerous to return to Hong Kong. Suddenly he
remembered a small 10-cent compass he had in his pocket, and it was
this that he used to fly 700 miles into the heart of China! At least,
this is how the story was reported in the Daily

compass, surrounded by the metal and electrical systems in an aircraft
compass, simply will not
work. The other thing is that
small warplanes in WW2 had propeller engines directly in front of the
cockpit, which would have driven a compass just 1.5 metres or less
away, completely wild. It's
a challenge to fly an a/c on an accurate heading using only the
calibrated, high quality magnetic compass, with crosswinds
etc…. 700 miles at night across unknown territory, without
visual reference to the land below, even with a high quality
magnetic compass, would be impossible… but with a toy*?
No… it's a hoax :-)
