How to correctly wind your automatic watch

Functions of the crown

NORMAL POSITION

When wearing the watch, the crown should be in position 0, the winding position. The winding position is also the “off” position for the crown.

WINDING POSITION

With the crown in the winding position (position 0), you can wind the movement by hand. Around 10 to 20 revolutions of the crown in the winding direction are enough to start the movement. Once fully wound, the watch’s maximum running time will be available, ensuring the precision and maintaining the movement’s rate even after taking off the watch and up to a few hours before the power reserve is depleted.

Watches with a power reserve display should be wound up to the 3-day marking on the power reserve. When wound up to the last marking, the watch has a power reserve that corresponds to the maximum running time of the watch in days as shown on the display. Maximum precision is ensured when the watch is fully wound.

DATE AND DAY SETTING

Pull the crown out to position 1. In this position, you can use the direct-advance function to move the calendar forwards one step at a time by turning the crown slowly to the right. The calendar must not be adjusted between 9 p.m. and 3 a.m. This would result in damage to a component in the calendar mechanism which would require repair by a watchmaker. The same applies to turning the crown too rapidly when setting the calendar.

You must not move the calendar beyond the correct date. The complicated movement is mechanically programmed and cannot be moved back in time without making a professional adjustment to the movement. However, if you do move the date forwards beyond the correct date, you have two options: you can either pull out the crown to position 2 to stop the movement until the calendar setting matches the correct date once again – this makes sense if the date has been set only a few days ahead – or, you take your watch to your watchmaker, who will be able to adjust the movement to reset the calendar. This is recommended in the event of larger maladjustments.

How to set the date on your watch


TIME SETTING

Before pulling the crown out to its limit to set the time, you should ensure that the watch still has a few hours’ power reserve. Otherwise, the crown should be pushed into position 0, the winding position, and the watch should be wound.

If the crown is completely pulled out, the movement will be automatically stopped and the time can be set by turning the crown.

You can set the time by turning the crown and positioning the minute hand exactly above the minute stroke. When doing this, move the minute hand a few minute strokes beyond the time to be set. The minute hand can be positioned exactly above the correct minute stroke by moving it backwards gently. This ensures that the minute hand begins to move immediately when you restart the movement.

Moving the hands forwards past midnight causes the calendar to switch to the following day. When advancing the calendar, you can follow and observe the automatic switching sequence.

To start the seconds hand, push in the crown to position 0.

POWER RESERVE DISPLAY

The power reserve display is divided into at least 7 days with continuous display. The winding mechanism winds the watch continuously while you are wearing it, and you can follow the process on the power reserve indicator. The marking in the area of the last day signals that the power reserve is about to expire. The watch should then be wound by hand, if necessary, since the precision can be reduced in this area. To maximise the running time of your watch, we recommend winding the crown up to 8 additional revolutions beyond the marking of the full power reserve (at least 7 full days).

How to set Portugieser Perpetual Calendar


THE MOON PHASE DISPLAY

The moon phase display shows the moon in the northern hemisphere in the upper half and the moon in the southern hemisphere in the lower half. It is automatically set by the calendar. The moon phase display is therefore always correct. The transmission ratio is so precise that the display deviates by only a single day after 577 years.

Your watch features a moon phase display, which, with the help of a transmission, displays the time from one full moon to the next with 29 days, 12 hours and 44 minutes as precisely as possible. The moon phase display advances in whole-day increments together with the calendar. As a full moon can occur at any time of night or day, it may be that your watch displays the calendar date of the full or new moon but that the moon phase display has not reached this position due to the exact time of the full or new moon. IWC sets the moon phase display so that it displays the full and new moon precisely on as many dates in the year as possible.

The transmission ratio has been calculated and realised with such accuracy that, in theory, the display will only deviate by a single day after several hundreds of years.

The arrows to the left and right of the moon phase display are used to indicate the number of days until the next full moon. The time that elapses between one full moon and the next is always exactly 29.530588402 days, which are represented as 29.5 days on the rotating moon phase display, in conjunction with the extremely precise perpetual calendar.

MOON PHASE SETTING

You should not use the rapid-advance function between 9 p.m. and 3 a.m. because the movement automatically advances the moon phase during this period. If the watch stops at any point, the display will need to be adjusted to the current moon phase. To do this, pull the crown out to position 1 and set the moon phase by turning the crown.

Method: Consult the lunar calendar to find the current moon phase. Count the number of days from the current date to the next full moon. Move the moon phase to the “full moon” position and rotate the crown to the left to turn it back by the number of days until the next full moon.


CROSSING THE INTERNATIONAL DATE LINE

Setting when crossing the International Date Line: When crossing the International Date Line in a westerly direction (you enter the next day, regardless of the time of day), simply turn the time forwards to the new local time, and the date change will take place automatically. When crossing the International Date Line in an easterly direction (you enter the previous day, regardless of the time of day), you must likewise set your watch forwards to the new local time. However, your watch will now indicate the wrong date (1 day too many). This incorrect date indication can be corrected by resetting the hands twice, by 12 hours on each occasion: Setting the watch back by 12 hours during the afternoon between 2 p.m. and 8 p.m. will prevent the calendar from advancing at midnight. Setting the watch back another 12 hours the following morning between 2 a.m. and 11 a.m. will synchronize the date display with the local date.

Setting when crossing time zones: When crossing time zones in an easterly direction, you should simply set the time forwards to the new local time. When crossing time zones in a westerly direction, you can set the hands of your watch back to the actual time of day. When doing this, however, you must not move back into the calendar’s automatic switching phase, i.e. beyond 2 a.m. If this situation occurs when you are travelling west, you should set the local time of your destination before 8 p.m. You must not turn the hands back between 8 p.m. and 2 a.m. This is because the calendar does not move backwards by 1 day when the hands are turned back beyond midnight, but remains on the same day. If you go past the end of the calendar’s switching phase (i.e. beyond 2 a.m.) when turning the hands back, you run the risk of the calendar advancing by 1 day for a second time and thus indicating 1 day too many.


INFORMATION ABOUT MAGNETIC FIELDS

Extremely strong permanent magnets are increasingly found in everyday objects and are an integral part of items such as fasteners on handbags, jewellery cases and cupboards, headphones and magnetic toys. The magnetic fields produced by such permanent magnets can negatively influence the precision of mechanical watches. Mechanical watches should be kept away from such magnetic fields.

However, should there be a sudden change in the precision of your timepiece despite your having taken precautions, please contact an authorized IWC Official Agent or an IWC service centre so that your watch can be demagnetized and restored by a specialist.


WATER-RESISTANCE

The water-resistance of IWC watches is stated in bar and not in metres. Metres, which are often used elsewhere in the watch industry to indicate water-resistance, cannot be equated with the dive depth because of the test procedures that are frequently used. The following are some examples for explanation: an IWC watch with an indicated water-resistance of 1 bar is protected against splashing water. With water-resistance of 3 to 5 bar, the watch can be worn when swimming or skiing, and at 6 to 12 bar it will have no problem with water sports or snorkeling. Diver’s watches with an indicated water-resistance as of 12 bar are professional measuring instruments designed for scuba-diving. Special diver’s watches resistant to 100 bar or 200 bar are suitable even for deep-sea diving. The recommended uses for IWC watches, depending on the degree of water-resistance, are established on this basis and on the basis of empirical data, and are indicated in the inserted table here.

Remember that temperature fluctuations and external influences – due to solvents, cosmetics or dust, or caused by shocks, impacts or sudden movements – can fundamentally affect the watch’s water-resistance. Therefore, before engaging in activities that could be potentially damaging to your watch (team sports, high diving, etc.), you are advised to put it in a safe place. Please also bear in mind that not every strap or bracelet is suitable for use in or under water because of the materials used in its construction. Furthermore, with the exception of diver’s watches, the moving parts of the watch (crown, buttons, etc.) should not be operated under water. Before wearing the watch in or under water, you should also ensure that all moving parts are in the “off” position.

It should also be noted that the water-resistance of a watch is not a permanent characteristic. Seals and sealing systems in particular are subject to wear and tear and natural ageing. To care for your IWC watch, please read the operating instructions carefully. After use in or under water, your watch should be rinsed with clear, fresh and lukewarm water and then cleaned and dried. The watch’s water-resistance should be tested regularly, and at least annually, by an authorized IWC Official Agent. Further instructions for care can be found in the corresponding operating instructions.

All the Aquatimer models feature an external/internal rotating bezel that is used to set dive times. The IWC SafeDive® system ensures that the internal rotating bezel can only be adjusted when the external bezel is rotated in an anticlockwise direction. As a result, even if the external bezel is accidentally moved, zero hour – the time at which the diver can return to the surface without the need for decompression stops – cannot be exceeded. Further instructions can be found in the corresponding operating instructions.

IWC SafeDive® is a trademark of IWC Schaffhausen registered in many jurisdictions worldwide.


SERVICING YOUR WATCH

The optimal service cycle for your IWC timepiece is exclusive to your watch and unique lifestyle. The necessary interval between services will be determined by your individual wearing habits – such as the frequency of wear, the environment(s) you live in and the intensity of physical activity you engage in. Your watch is a finely tuned mechanical instrument. The more carefully you handle your watch, the longer it will continue to function flawlessly. We simply recommend that you continue wearing your watch for as long as you please and to only entrust it for a service if you notice a deviation from the regular performance, function or timekeeping. In this case, we will be happy to return your watch to its original performance level as part of servicing.
