GUARANTEE
Each HYT watch bears an individual identification number, which guarantees both its
authenticity, and that all the work involved in its creation has been supervised by a master
watchmaker.
Each HYT watch is equipped with a fluid module0. The fluid module is the device, which
enables to display time via the meniscus1. The meniscus1marks the boundary between
the two non-miscible fluids in the tube. The watch movement drives the module via the
bellows2fixed on the main plate. Only a professional watchmaker approved by HYT can
replace this fluidic system. It bears a unique serial number.
The smart card you received when you purchased your watch is the electronic guarantee
certificate for your HYT watch.
The highly secure digital information contained in the chip is unique and tamper-proof.
The guarantee is activated during the purchase in our network of approved HYT retailers.
You must present your activated guarantee card to benefit from the guarantee.
On the front, you can see the electronic chip, the reference, the serial number of the
watch and its individual number.
Your HYT smart card gives you access to information relating to your watch and proves
its authenticity. To check this, simply go to lounge.hytwatches.com/authenticate and
follow the instructions.
In addition to this, using the HYT smart card and the reader gives you access to the «HYT
lounge», your personalised customer space at lounge.hytwatches.com.
In this manual, you can find the basic instructions for using and maintaining your watch.
Your HYT watch is guaranteed against all manufacturing defects for two years from the
date it was purchased, if the watch was purchased from an approved HYT retailer. This
guarantee does not however cover damage caused by incorrect handling or improper use
of the watch.
If your watch requires a maintenance procedure during the guarantee period, please
provide your smart card activated by a HYT retailer.
For any service, repair or maintenance procedure, please ensure you only use retailers
approved by HYT or our after-sales service centre.
You can find the list of our network of approved retailers and our after-sales service on
our website www.hytwatches.com.
Any repair or maintenance work carried out by third parties who have not been approved
by HYT will automatically void the guarantee. Any damage caused will then have to be
repaired at your expense.

PRECAUTIONS FOR USEPRECAUTIONS FOR USE
Your HYT watch is set and ready to be worn.
The meniscus1in its capillary3and the time it displays will remain constant while the
watch is on your wrist, even if you wear it in extreme temperatures (0°C to +50°C).
Important : If you plan to not wear the watch for a
while, the green liquid has to be stored in its own
reservoir (on the left bellow2).
Therefore, when the watch is stopped (the power-
reserve is empty and the power reserve hand
indicates 00) you have to manually and slowly
move this colored liquid until the latter reaches
the «Zone I».
The capillary3is at that time fully filled with the
transparent liquid (there is no more or very little
green liquid visible in the tube). A special molecule
within this transparent liquid will maintain the
capillary in the optimized conditions.
Produced and tested to very stringent criteria, the constituent components of your HYT
watch together form an exceptionally watertight unit (to a depth of 100 metres). To
ensure these qualities are preserved, we recommend that you replace the gaskets and the
crown every 3 years. Temperature variations, moisture, perspiration or repeated impacts
may adversely aect its water resistance over the years.
With its sealed case and rubber strap, your HYT is fully washable. It should be cleaned
regularly in warm, soapy water, rinsed and then carefully dried with a soft cloth. After
exposure to sea water, rinse your HYT watch in fresh water.

0. Fluid module:
To create a liquid indication of time that is small, wearable and multi-purpose, HYT
embarked on a completely new idea, using two flexible reservoirs at each end of a
capillary tube. The system is sealed, with each reservoir containing a liquid of a dierent
colour and dierent density. The Fluid module represents this complete system.
1. Meniscus:
The two fluids are separated by the positive and negative polarities of the molecules of
each that keep them apart like magnetic repulsion. The meniscus marks the breaking
point with the other fluid in the tube, indicating the time.
2. Bellows:
The bellows are the two reservoirs (located at 6 o’clock) made of a highly resistant,
flexible electro-deposited alloy, each driven by a piston. This is where watchmaking
comes in to activate the system. When one is emptied, the other fillls, and vice-versa,
moving the liquid along the tube.
3. Capillary:
The round glass tube, milled to form a circle, the capillary, in which the two non-miscible
fluids flow.
4. Retrograde:
When the fluorescent liquid gets to 6pm hours; it flows black to its original position,
going backwards.

SCREW-DOWN CROWN
Pos A.
INTRODUCTION
This type of crown provides excellent protection to ensure the case is watertight.
The crown must be unscrewed before changing the watch settings and screwed back
down afterwards.
HOW TO USE
• Unscrew the crown before changing the watch settings
• Afterwards, push the crown back in against the case and screw it back down
• Check from time to time that the crown is fully screwed down.

SETTING THE TIME
Pos C.
Zone I Zone II
10 minutes = 1 crown movement
= 1 sec of manipulation
INTRODUCTION
This function allows the time shown on your watch to be set using the crown.
IMPORTANT
• To move nanofluids within a capillary3should require no less caution than setting a
perpetual calendar or a minute repeater
• We highly recommend to move the fluid by 10 minutes on each crown movement
• The «speed» of the minute hand covering 10 minutes each sequence is approximately
1-2 seconds
• It is not particulary slow, as you will move the fluid for a full hour in approximately
12 seconds in total.
HOW TO USE
• Unscrew the crown and pull it out to position C
• Then turn the crown in either direction until the coloured liquid (hour display) and the
minute hand is at the time required
• Push the crown in completely against the case
• Do not forget to screw in the crown completely to ensure its water resistance.
RETROGRADE
• The automatic return of the fluid (retrograde)4 is
allowed by the pressure of the two bellows2. The
speed is higher when the retrograde4starts at
6:00 in «Zone II» and is minimal when the liquid
approaches its starting point in «Zone I».

have nevertheless to also respect the speed limit when
handling your fluid.
It is however totally forbidden to continue the counter
clockwise handling if the coloured fluid is not visible

POWER RESERVE
INDICATOR
INTRODUCTION
This power reserve indicator function provides a real-time display of your watch’s
current power, thereby indicating how long it will continue to run without the spring
being rewound.
HOW TO USE
The display uses a small hand on the dial which travels in an arc from the «full» to
«empty» symbol.
To ensure optimal operation of the watch, we recommend that you check it is fully
wound (see WINDING).
