WATCHES

SETTINGS

SCREWED-DOWN POSITION [position A]

Your TUDOR watch is equipped with a screw-down crown.
Once this is fully screwed down against the case, your
watch is guaranteed waterproof.

MANUAL WINDING [position B]

A watch equipped with a self-winding mechanical
movement is wound automatically by wrist movements
alone. To ensure optimum winding, wear your watch
daily.

Before you rst use the watch or if it has stopped, you will
need to wind it manually by unscrewing the crown and
then turning it clockwise; the other direction is inactive.

SETTING THE REFERENCE TIME [position D]

To set the reference time, unscrew the crown and then pull
it out to the second notch. The seconds hand is stopped,
allowing you to set the time to the precise second.

Put the bezel in the neutral position (align the triangle
onthebezel with the 12 o’clock marker on the dial).

Set the reference time using the 24-hour hand (against the
graduations on the bezel) and the minute hand (against
the graduations on the dial) by turning the crown in either
direction.

Setting the reference time also moves the conventional hour
hand (local time). For this reason, the reference time must be
set before setting the local time.

REFERENCE TIME
Geneva: 10:10 a.m.

A B C D

SETTING THE DATE AND THE LOCAL TIME [position C]

To set the date and the local time, pull the crown out to the rst
notch.

Set the date by turning the crown in either direction. The hour
hand moves in increments of one hour. The date changes when
the hour hand passes midnight, in either direction, aer two
complete turns around the dial.

Set the local time by turning the crown in either direction. The
hour hand moves in increments of one hour. Be aware of the
dierence between noon and midnight (the date changes as
the hour hand passes midnight).

Push in and then screw down the crown.

REFERENCE TIME
Geneva: 10:10 a.m.

LOCAL TIME

New York: 4:10 a.m.

The local time is identical to the reference time (24-hour hand)
if the wearer is currently located in his reference zone. It can be
easily adjusted when travelling.

ADJUSTING THE LOCAL TIME [position C]

When travelling, to adjust local time only (without aecting the
24-hour reference time display), unscrew the crown and then
pull it out to the rst notch.

Set the local time by turning the crown in either direction. The
hour hand moves in increments of one hour. The date is linked
to local time and changes automatically when the hour hand
passes midnight.

Push in and then screw down the crown.
The 24-hour hand indicates the time in the reference time zone

and allows the wearer to distinguish daytime hours from night­time hours.

THIRD TIME ZONE DISPLAY
[setting via the bezel only]

A third time zone can be displayed by using the rotatable bezel
and the 24-hour hand. It is based on the reference time.

To display the third time zone, turn the bezel clockwise (for
anegative time dierence) or anticlockwise (for a positive
time dierence) according to the time dierence between the
reference time (24-hour hand) and the time in the desired time
zone.

The 24-hour hand read against the bezel indicates the time in
the third time zone. The minutes are shown on the dial by the
minute hand.

REFERENCE TIME
Geneva: 10:10 a.m.

LOCAL TIME

New York: 4:10 a.m.

TIME IN THE THIRD

TIME ZONE

Tokyo: 6:10 p.m.

To return to the reference time display, turn the bezel in
either direction to place the triangle on the bezel opposite
the12o’clock marker on the dial.

Bronze: Your Black Bay Bronze is designed in bronze, in
this case a high-performance aluminium bronze alloy,
which guarantees the development of a subtle and unique
patina to match its user’s habits.

Cleaning: Use a microbre cloth and wash the metal,
rubber, fabric bracelets and waterproof cases from time
to time with a so brush and soapy water. We recommend
that you do not use abrasive or corrosive products
(solvents, detergents, perfume, etc.).

Guarantee: Refer to the guarantee manual supplied
with your watch.

Leather: To preserve your leather strap, we recommend
protecting it from water and moisture.

PVD: Your Black Bay Dark is nished with a black coating
obtained using a Physical Vapour Deposition (PVD)
process. Although the coating is extremely resistant,
regular wear and tear can cause this decorative layer to
deteriorate over time. The warranty does not cover
this type of aesthetic wear.

RECOMMENDATIONS

Salt water: Always rinse your watch with fresh water.
Screw-down winding crown: Aer each operation,

remember to push the crown back in and screw it back
down carefully against the case, in order to preserve
your watch’s waterproofness.

Service: Each TUDOR watch is a complex precision
mechanism and, as such, requires periodic servicing and
maintenance to guarantee optimum performance. Expert
TUDOR servicing can be carried out via any of the Ocial
Retailers and Service Centres in the extensive ROLEX or
TUDOR service network. Visit TUDORWATCH.COM to view
the list of Ocial TUDOR Retailers and Service Centres in
