Greetings. I'm Tim of Govberg and welcome to the world of Zenith. Today I'll be your guide to the proper operation, care and maintenance of your Zenith El Primero Tourbillon. It's important to note that, at any point, you can refer to our experts at our website, Govbergwatches.com, text, all or email for step by step instructions in the proper handling of this timepiece.

To wind the watch, this automatic winding timepiece can nevertheless be manually energized should it run down by turning the crown in its first position flush to the case in a clockwise direction. Approximately 20 to 30 turns will be sufficient to start the oscillator and you'll note the advance of the Tourbillon cage once the watch has sufficient energy to begin keeping time. Now at this point, you can put the watch on your wrist and the natural course of kinetic action on the wrist will turn the winding rotor, fully energizing the power reserve of approximately 50 hours. Should you wish to wind the watch to its full rated power reserve, simply continue turning the crown. This automatic winding watch cannot be accidentally manually or automatically over wound as the bridal-style mainspring will simply slip and relieve any excess tension.

When setting the watch, it's important to note that an El Primero sets time and date differently than conventional calibers. In the first position, the watch's time is set. This is different from most movements, which use the first position out from flush with the case to set the date. Simply advance to the desired time and once the proper hour and minute are set, you'll note seconds continue to advance, even while you're setting. Simply replace the crown to the position flush to the case.

Now in the outermost position, the date is set. The date should only be advanced using the quick-set mechanism between hours exclusive of 8PM and 4AM, as this is the period during which the automatic jumper mechanism of the date is engaged. You'll note the date is a circumferential ring surrounding the Tourbillon. It does have its own automatic changeover during the wee hours of the night. Be careful. Never attempt to use the quick-set for the date during the hours between 8PM and 4AM as attempting to do so will severely damage the movement. Always be cautious if you are setting the time between the hours of 8PM and 4AM that you don't accidentally pull the crown out to extremity and start to turn it as though this were conventional caliber. Remember, that is the date-setting position.

Now it's also important to note with respect to the chronograph operation that there is a proper sequence to be followed. Always start and stop the chronograph with the pusher at 2 o'clock and always reset the pusher at 4. However, never attempt to reset the mechanism while the chronograph is running, as attempting to reset out of sequence without stopping the mechanism will severely damage the chronograph.

There are three primary hazards that need to be considered with respect to the longevity and care of your watch. First and foremost is water resistance. Now this is a robust timepiece rated to 100 meters' water resistance, which Zenith describes as sufficient for shallow diving, snorkeling and submergence. However, it should be noted that while the watch is 100 meters' water resistant, no leather strap is water resistant. Leather is a natural, porous material that will degrade rapidly in the presence of moisture or submergence so always swap out to a rubber or textile strap or bracelet before submerging or wetting the timepiece.

The magnetism is another significant risk to your watch and it is, in a lot of ways, a silent killer. While it won't permanently damage your timepiece, magnetism affects the movement in a sidious fashion by magnetizing the hairspring within the balance wheel. A magnet will cause erratic timing of your watch. Magnets are more common in daily life than many suspect, being used in the closure of certain packages, purses as well as wallets, speakers, subwoofers, high-powered home and office wiring looms, refrigerator doors and, of course, magnetic resonance imaging equipment. If you suspect, due to erratic timing, that your watch has become magnetized, take it to an authorized dealer where equipment is available to quickly and easily demagnetize your hairspring.
