USER INSTRUCTIONS
GRANT
You have just adopted Grant, one of the most
advanced timepieces born from a partnership
between La Manufacture L’Epée 1839 and MB&F.
Grant has been developed with passion and care
by the Master Watchmakers of L’Epée 1839 in Delémont,
Switzerland.

Please, be very careful to never touch the movement of
Grant either on the front, on the sides or on the back of the
movement, except for the time adjustment and winding
tips that can be touched with the winding key.
Furthermore, the movement should never be in contact
with any liquids – even in vaporized form. If this occurs, the
clock should be serviced immediately.
A simple contact with certain pieces can generate delays in
timekeeping, which can only be solved by servicing.
Fingerprints will also damage the coating so always wear
gloves when manipulating the clock. Accidental nger-
prints should be wiped off immediately.
On the following illustrations, the only parts which can be
cleaned and touched with precaution are those outside of
the zone coloured in red; in case of intrusions, a service
will be needed.
IMPORTANT INFORMATION
7
Use only a soft and dry cloth to clean the clock. Dust and
particles contained in the cloth could scratch parts. Do not
use any kind of cleaning products to clean the clock. It is
recommended to keep the clock distant from any source of
heat or vibrations. To preserve the longevity and function-
ality of Grant, do not permanently expose the clock to di-
rect sunlight or in a humid/dusty place.
Our clocks are developed to ensure optimal accuracy and
reliability. It is well accepted for a ne mechanical clock to
have a few seconds’ variation per day and our clocks are
set so as not to delay. However if you should notice a big-
ger variation, please contact an authorised dealer who will
advise you, or a L’Epée 1839 technical support centre
which will proceed with the necessary adjustment.
As for all Horological pieces of art, it is recommended to
periodically service your clock. A mechanical masterpiece
requires ne oils for the lubrication of the movement.
These oils deteriorate over the years. We therefore advise
having the movement serviced every 3 to 5 years. Be aware
that the optimal period between servicing times can vary
depending on the surrounding environmental conditions.
It is recommended not to hold Grant only by one “arm”, or
by the top parts, but from underneath, with gloves – and
with the thumb on the shield to hold it in place and ensure
that it does not open accidentally while handling.
Do not roll Grant too quickly forward or backward; this
could result in the caterpillar tracks disengaging from the
rollers.
CARE AND MAINTENANCE
8
Grant can transform into one of three different modes:
lying horizontally over his chassis for a low prole; crouch-
ing at 45 degrees; or sitting up 90 degrees. In this way
Grant’s time shield can always be set to a comfortable and
optimal viewing angle.
OPENING
How to transform Grant from one position to another:
Hold the shield and lift it until you hear and see the pin of
his left arm (the arm with the spinning disk) lock into its
slot.
First slot: Grant’s torso locks securely into place at 45
degrees.
Second slot: Grant’s torso sits up straight at 90 degrees to
his chassis, with his shield now lying vertically along his
back.
CLOSING
How to place Grant back into the at position:
Hold the shield, lift his left arm (with the spinning disk) to
unlock the position, and gently let the shield down.
Release the arm for the intermediate position or continue
to lift it until the at position. In any case, when transform-
ing Grant, never let go of the shield and allow it to drop:
this could damage the balance wheel.
A KINETIC SCULPTURE

10
The double-depth square socket key is located on Grant’s
right hand. When you need the key to set the time or wind
the movement, pull it out gently from its resting position.
When putting it back into place, be careful to not place it
vertically: it could hit the movement when you move Grant
since the key is not locked into place.
THE WINDING AND TIME-SETTING KEY
11
Winding the movement can only be done when Grant is in
the fully horizontal position.
After placing Grant in the horizontal position, turn him
over very carefully and insert the key in Point A. Wind the
movement with anti-clockwise rotations.
The movement should be fully wound once a week (the
clock’s power reserve is 8 days). Be sure to wind up the
spring completely: you will notice that the necessary force
increases signicantly, but do not wind further as this is the
sign that the movement is fully wound. Excessive winding
beyond this point will damage the spring, requiring
servicing.

READING THE TIME
The hours and minutes are indicated by two hands on the
shield:
In this example it is 02:50
In this example it is 08:25

SETTING THE TIME
Place Grant in the fully upright position. Insert the key in
point B on the diagram and turn the key anti-clockwise in
order to set the time.

THE THREE CATERPILLAR TRACKS
Do not push too hard or too fast on the top or back of Grant
to move him forward or backward. A sharp turn could force
the rear caterpillar tracks off the rollers.
If this happens, gently push Grant forward in a straight line
and the caterpillar tracks should automatically return to their
normal position on the rollers.
15
CLEANING THE CATERPILLAR TRACKS
To clean the caterpillar tracks always use gloves. Remove
the rear caterpillar tracks by placing your nger between
the roller and the caterpillar track, and then gently pull it
off. Clean it with soapy water and let it air dry.
To put it back on, stretch the caterpillar track between the
two biggest rollers to place it approximately, and gently
push Grant forward in a straight line; the caterpillar track
should automatically return to its normal position on the
rollers. Be aware that you can’t remove the front caterpillar
track. It is therefore recommended to clean it gently with
just a small amount of soapy water.
