GUARANTEE
In this manual, you can nd the basic instructions for using and maintaining your watch.
Each HYT watch bears an individual identication 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 uidic module1. This device enables the time to
be displayed via the meniscus2. The meniscus marks the boundary between the two
immiscible uids in the capillary4. The watch movement drives the module via the bellows3
xed on the main plate. Only a professional watchmaker approved by HYT can replace
this uidic system. It bears a unique serial number.
The card you received when you purchased your watch is the electronic guarantee
certicate for your HYT watch.
The QR Code on the front of your card gives you access to unique and interactive content,
once you have downloaded the app. This content explains the correct way to use your
watch, with specic videos and texts.
The guarantee is activated upon purchase in our network of approved HYT retailers. You
must present your activated guarantee card to be entitled to the guarantee.
If following your purchase you have not received a conrmation e-mail, please go to
www.hytwatches.com/lounge. Then select the market place corresponding to your mobile.
The app will ask you to scan the QR Code and enter your e-mail, in order to send you a
password. By downloading this app, you will be able to contact our customer services in a
single click in case of an incident or if you have any questions.
Your HYT watch is guaranteed against all manufacturing defects for ve 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.
For any service, repair or maintenance procedure, please ensure you only use retailers
approved by HYT or our customer services.
You can nd the list of our network of approved retailers 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.
A colored liquid documents the recent past; a transparent uid indicates the foreseeable
future. Their meeting point is a meniscus in the capillary, aka the now.
Important : If you plan to not wear the watch for
a while, the colored liquid has to be stored in its
own reservoir (on the left bellow).
To do this, pull the crown out to position C
(time setting). Allow the colored liquid to move
into “Zone II” until it starts rewinding. Once the
rewinding phase is complete (colored liquid in
“Zone I”), ensure that the crown remains in the
time setting position C. Your watch is now ready to
be stopped for an extended period.
The capillary is then filled with transparent liquid
(it is possible to still see some colored liquid in
“Zone I”).
Produced and tested to stringent criteria, the constituent components of your HYT
watch together form an exceptionally water resistant unit. To ensure these qualities are
preserved, we recommend that you have the gaskets replaced during a service at an
authorized retailer. Temperature variations, moisture, perspiration or repeated impacts
may adversely affect its water resistance over the years.
With its water resistant case, your HYT watch is fully washable. It should be cleaned
regularly in lukewarm, soapy water, rinsed and then carefully dried with a soft cloth. After
exposure to sea water, rinse your HYT watch in fresh water.

GLOSSARY
1. Fluidic module:
To create a liquid time indicator that is compact, and wearable, HYT has developed a
completely new high-tech concept, using two exible bellows at each end of a capillary
tube. The system is sealed in accordance with the most stringent standards used in
the aerospace industry, with each bellow containing immiscible liquids. The exclusive
patented uidic module represents this complete system.
2. Meniscus:
The two liquids are separated by their intrinsic repulsive properties. The meniscus marks
the surface separating the liquids in the tube, indicating the time.
3. Bellows:
The bellows are the two reservoirs located at 6 o’clock. They are made of a highly
resistant, exible alloy four times ner than a human hair. The movement compresses
the left-hand bellow which is emptied of its colored liquid. The other bellow then lls,
and vice versa, moving the liquid within the capillary, and with it the meniscus which
indicates the time.
4. Capillary:
This tube, made from the best quality glass as used in the medical industry, is circular in
shape and contains two immiscible liquids. A surface treatment is applied to the inside
of the capillary, which enables the two liquids to move smoothly without adhering to the
glass.
5. Rewind:
When the colored liquid gets to 6 o’clock (Zone II), it switches to rewind mode, owing
back to its original position (Zone I).

INTRODUCTION
This function ensures that the power required to drive your watch is stored by the
movement.
HOW TO USE
• Pull out the crown from “A” to “B” before changing the watch settings
• Wind the watch by turning the crown clockwise “B”
• Afterwards, push the crown back in against the case “A”.

SETTING THE TIME
Pos C.
Turning the crown for 1 second
represents one crown rotation,
equivalent to a time shift of
20 minutes.
INTRODUCTION
This function allows the time shown on your watch to be set using the crown.
IMPORTANT
• The microuids in the capillary are moved via the smooth turning of the crown.
• We recommend moving the fluid by a 20-minute interval per crown manipulation.
• This means it should take three manipulations of 1 second to move the fluid a
distance equivalent to 1 hour.
HOW TO USE
• Pull out the crown to position “C”
• Then turn the crown in either direction until the coloured liquid (hour display) and the
minutes hand is at the time required
REWIND
• The automatic return of the colored liquid (rewind)5
is allowed by the pressure of the two bellows. The
speed is higher when the rewind starts in “Zone
II” and is minimal when the liquid approaches its
starting point in “Zone I”.

POWER RESERVE INDICATOR
Empty Full
INTRODUCTION
The power reserve indicator function provides a real-time display of your watch’s power,
thereby indicating how long it will continue to run without the spring being rewound.
To observe this indication, you have to turn the watch over.
HOW TO USE
The two barrels use two different signals: “lOw”, located on the left barrel, and “hIgh”
on the right barrel (see the image above).
When the mainsprings are wound, the arrow points to the “hIgh” signal; the power
reserve is “full”, representing 8 days of power reserve.
When the mainsprings are unwound, the arrow points to the “LOW” signal; the power
reserve is “empty”, and the movement needs to be wound (see WINDING)
To ensure optimal operation of the watch, we recommend that you check the movement
is fully wound (see WINDING).

THERMAL INDICATOR
INTRODUCTION
This thermal indicator shows if the watch is in its optimal temperature range to be handled.
When the hand points to the area, the temperature of the watch is less than 15°C. In
this case, we recommended that handling of your watch is avoided - particularly any
rewind movement.
When the hand points to the area, the temperature of the watch is higher than 15°C.
The watch can be handled with care (see SETTING THE TIME).
The hand will move back to the white area after your watch is worn for 30-40 min.
