Greetings and welcome to the world of IWC. Today we're discussing the proper usage, care, and maintenance of the IWC Pilot's watch chronograph edition Le Petit Prince, reference 3777-14. This automatic winding time piece can, nevertheless, be wound manually by screwing the crown out from its position flush with the case, and should the watch run down, simply turn the crown clockwise until the seconds hand can be seen moving across the dial. Either chronograph seconds or the constant seconds indicator can let you know that the watch is no functioning.

You can put the watch on the wrist at this point and via the kinetic energy of the wrist, the automatic winding system will continue to energize the 44 hour power reserve up to capacity. It's important to note that should you wish to wind the watch to capacity, this automatic time piece cannot be over wound. At the limit, the bridal main spring will slip preventing damage.

Once the watch is wound, two additional refinements assist in setting the time as well as the day and the date. When pulled to extremity, the crown activates a hacking function, such that the balance stops, the march of the seconds halts, and now the watch can be set to a known accurate reference time. In the second position, the watch features a quick set date function, such that the day and the date can be cycled by moving the crown in opposite directions. It's important to note that the quick set day/date function should never be engaged during the hours of 9p.m. and 3a.m., as this is the period that the movements automatic date jumper is engaged and you can cause damage to the movement.

Once watch has been wound, set, and the day and date corrected, it's important to always screw the crown back in to protect it from damage from abrasion or impact. Once the crown is screwed in, the watch achieves it's factory rated 60 meters of water tight hermeticity. Now it's important to remember that there's several caveats relating to water resistance. First, when the watch has been serviced, it's important to recognize that it does have high limits than some time pieces, such that IWC approves the water resistance for swimming and most water sports, but this can only be obtained by annually testing the watch at an authorized IWC retailer to ensure that that six ATM of hermeticity is retained. Water resistance is not a static property of a time piece, and it's important on an annual basis to acknowledge that lubricants dry and seals age. Have the seals for the crown, gasket, and case back checked using equipment onsite at your IWC authorized retailer to protect the integrity of your time piece. If you wish to use your watch in the water, have it fitted with a textile strap or metal bracelet, both available from IWC.

Finally, with respect to functions of the time piece, such as the chronograph, water resistance is compromised should the crown be screwed out and used for any of its setting functions, or should the chronograph pushers start, stop, and reset be actuated while the watch is either wet or submerged. Should you suspect that the water tight integrity of your watch has been bypassed, for instance due to condensation under the crystal, immediately take it to an IWC authorized retailer or service center for rapid correction of a condition that can cause both cosmetic and mechanical damage to your watch.

With respect to chronograph functions, there are certain limitations that must be observed, specifically start, stop, and reset must always be in sequence. The crown at 2'oclock is the chronograph pusher that starts and stops the chronograph. The pusher at 4'oclock, which should only be actuated with the chronograph stopped and the chronograph seconds hand not moving, resets the time piece's stop watch function. Always remember start, stop, and reset in precisely that order. All IWC's Pilot's watches feature a soft iron para-magnetic cage around the movement. This is designed to channel magnetic field lines around the sensitive hair spring of the watch. Should you suspect, however, that a powerful magnetic flux, such as that created by an MRI, has magnetized your time piece, take it to an authorized dealer or service center where specialized equipment is available onsite to demagnetize your watch.

Service is important for every mechanical watch, both for performance and for the integrity of your investment. Only service your watch with IWC authorized retailers, such as independent dealers authorized by the factory and factory owned boutiques. These alone have access to the trained personnel, specialized equipment, and original factory replacement parts necessary to preserve the value and functional integrity of your IWC.
