THE FOLLOWING TIPS WILL HELP YOU TO ADJUST YOUR WATCH AND TO CARE FOR AND PROTECT IT OPTIMALLY.

Timepieces are highly developed precision instruments that work continuously and under often difficult conditions. On this page you will find important information on how to handle and care for your watch.

HANDLING IN EVERYDAY LIFE

Even though most manufacturers affirm that you can wear your own timepieces while doing sports or gardening, this does not really make sense in the case of a valuable precision instrument.
Even the most robust calibers and cases can be subjected to severe shocks and vibrations and the sensitive mechanics of the movement can be damaged. In case of doubt, it is therefore better to take the watch off or leave it at home once more than to be annoyed by scratches on the case or damage to the movement afterwards.

AUTOMATIC WATCHES

The movement of an automatic watch is wound up by the movements of your wrist. Therefore, we recommend that you wear your automatic watch every day so that it is wound up automatically as you move your wrist.
If your watch stops, it should be wound manually before you wear it again. To do this, wind the movement by turning the crown a few turns and restart it.
If your daily activity is not sufficient to wind the movement automatically, you can easily compensate for the insufficient tension of the spring by winding it manually via the crown.

MANUAL WINDING WATCHES

A hand-wound watch must be wound by hand.
Wind your watch by turning the crown clockwise until you feel a noticeable resistance. Do not attempt to wind your watch beyond this resistance as this will damage the mainspring.
When fully wound, your watch usually has a power reserve of 35 hours or more. Sufficient tension of the mainspring has a beneficial effect on the accuracy of the watch. If you are not wearing your mechanical watch, you should wind it once a month.

QUARTZ WATCHES

Watches with quartz movements are powered by a battery and therefore do not need to be wound.
The battery of a quartz watch must be changed when the second hand starts moving at 5-second intervals. In watches without a second hand, an empty battery only becomes noticeable when the hands come to a complete standstill. To prevent the battery from leaking and thus damaging the movement, it should be replaced as soon as possible.
The battery, which is due for replacement every 1-2 years, should only be replaced by Rent a Box or another specialist store.

SETTING THE DATE

The date of many mechanical watches is set as follows:

1.  If necessary, loosen the screw-down crown and pull it to position 2.
2. You can now adjust the date by turning the crown clockwise.
3. You should never correct the date between 8 p.m. and 2 a.m., as the date is automatically advanced by the movement during this time and serious damage to the movement may occur.
4. Now push the crown back to position 1 and secure it by simultaneously pushing and turning it to the right.

To prevent the date from advancing at noon instead of midnight, the date should be set BEFORE the time:

1. Set the date to 1 day before the current date.
2. Use the time setting function to move the date one day further.
3. Now set the current time.

SETTING THE TIME

The following positions are valid in most cases for setting the time. If the time setting of your watch is different from the one described here, we have pointed this out to you when you purchased your watch.

1.    If your watch has a screw-down crown, unlock the crown by turning it counterclockwise.
2. Pull the crown out to position 3.
3. Turn clockwise to set the desired time.
4. Now push the crown back into position 1 and secure it by pressing and turning it to the right at the same time if necessary.

CHRONOGRAPHS

Chronographs are time recorders. They measure time, give it a frame and record the duration of an activity. The additional function of short time measurement allows the second hand to be started, stopped and then returned to its starting position independently.

Start / Stopp: You start and stop the chronograph by pressing the start/stop button (upper button).
Reset: Press the Reset and Flyback Pusher to reset all chronograph hands to zero (lower pusher). Note: If your chronograph does not have a flyback function, it is very important to stop the chronograph before resetting, otherwise there is a risk of damaging the mechanism.
Second counter: The large seconds counter in the center of the dial is the stop-seconds hand. On the edge of the dial is the division for reading the stopped seconds.
Minute counter: The minutes are read on a subdial with 30 or 60 minute divisions. The minute counter can be read like the normal analog time display, i.e. one revolution of the minute counter corresponds to 30 or 60 minutes.
Flyback: When the chronograph is running, a new measurement can be started immediately. To do this, press the reset and flyback push-button fully to the stop while the chronograph is running. Both chronograph hands are reset and a new measurement is started immediately when the push button is released.
Addition time measurement: You can add the stop times by pressing the start/stop button again after the first measurement instead of the reset and flyback button.
Rattrapante: In chronographs with rattrapante or split-seconds function, an intermediate or lap time can be measured by pressing the additional push-piece.

LEATHER STRAPS

Leather is a natural product that requires special care:

  • - Avoid contact with water. Even high humidity and sweat can deform and fade the material. Only leather straps that are explicitly marked as waterproof can be cleaned under running water.
  • - Cosmetics, cleaning agents and oily substances can leave stains.
  • - Excessive exposure to sunlight can have a damaging effect on color and quality.
  • - If used daily, leather straps should be changed after one year, also for hygienic reasons.

METAL AND RUBBER STRAPS

For watches worn daily, we recommend cleaning the strap every six months as follows

  • - Clean the bracelet with a soft brush or toothbrush soaked in soapy water.
  • - Rinse it carefully with tap water.
  • - Dry it with a soft, dry cloth.
  • - Clean your bracelet in the same way after a swim in the sea or swimming pool.

GENERAL USE OF THE WATCH

  • - Avoid direct contact of the watch and bracelet with cleaning products, cosmetics, perfumes, etc. These products can damage the case, strap and seals.
  • - Do not place the watch on devices that emit strong magnetic fields. E.g. clock radios, loudspeakers, refrigerators, etc.
  • - Do not expose the watch to extreme temperatures of more than 60° C and less than -5° C. Avoid shock-like temperature fluctuations, such as those that occur in saunas.
  • - Timepieces, like any device with mechanical parts, require maintenance from time to time. However, the need for maintenance depends greatly on the individual use and care of the watch. With normal, careful use, we recommend an inspection every 4 - 5 years.
