Congratulations
We would like to congratulate you on having chosen a chronograph MIDO
®
, one of the most highly renowned Swiss brands in the world. Meticulously designed,
using only the highest quality materials and components, your chronograph is protected against shock loads, variations in temperature, water and dust.
When operating as a chronograph, this model is able to time events lasting up to 30 minutes, displaying the results to the 1/10th of a second, and also provides
you with the following functions:
– Standard START–STOP function
– ADD function (partial times)
– SPLIT function (intermediate times)
To ensure that your chronograph operates with perfect precision for many years to come, we advise you to pay very careful attention to the advice provided hereafter.
Important information
Mido has always been one of the pioneers of waterresistant watches.
Before changing any settings, please
read and follow the instructions given below :
If you have selected a
Commander Ocean Star model,
you have chosen a watch with a one-piece case
(monocoque) which ensures complete water-resistance. This concept comprises a two-section winding shaft. As a
consequence,
you must carefully pull the crown into setting positions II and III
because it can be pulled out
completely if too much force is applied. If this problem arises, please contact your sales agent who will reinstall the
crown for you and check over the water-resistance.
If you have selected a model with the
Aquadura
system, you have chosen a unique system capable of assuring complete water-resistance thanks to a gasket made
of cork which fully encircles the crown shaft.
Before pulling out the crown, rotate it by two or three turns.
Settings
Models with a screwed crown
To ensure that they remain water-resistant, some models are fitted with a screwed crown. Before proceeding to setting the time or date, you must first unscrew the
crown into position IB before pulling it out into position
II
or
III.
Important : After each operation, you must always screw the crown back down to ensure that your watch remains water-resistant.
Setting the time
Pull the crown out to position
III
and turn it clockwise or counterclockwise to set the desired time. Synchronize the small seconds-hand, located at 6 o’clock, to
an official time signal (radio/TV/Internet) by pulling out the crown to its second stop; the seconds hand stops at this point. As soon as the time setting has been
synchronized, push the crown back down into position
I
(and tighten it back down on models with a screwed crown).
Winding
Quartz chronographs never need to be wind.
Rapid correction of the date
Pull the crown out into position
II
and turn it forwards until the correct date is displayed. During this operation, only the hour hand rotates.
Setting the counters to zero
After changing the battery or, exceptionally, in the event of a malfunction, the counters need to be initialised
(i.e. zeroised) before starting to use the chronometer. If necessary, proceed as follows:
1
60 seconds counter hand (crown in position
III
, pusher
A
)
2
30 minutes counter hand or 12 hours counter (crown in position
II
, pusher
B
)
3
1/10 of a second counter hand (crown in position
III
, pusher
B
)
Simple chronograph (timing) operation
The simple « chronograph function » enables you to measure isolated events.

All the timing functions are available while the crown is pressed into position
