The crown in Vostok watches is intentionally designed to be wobbly. This might seem strange, but it's normal. So don't worry if you notice some movement in the crown - that's just how it's supposed to be. Winding.If you wear a watch on your hand every day there's no need to wind it up, but remember to wind your watch up if you haven't worn it for more than a day. This will ensure that it keeps accurate time and functions properly.Unscrew the crown counterclockwise and then set it to position 2. Start winding by turning the crown by 25-30 turns. Screw the crown back. Adjusting the time.Set the crown to position 3. Turning the crown counterclockwise to set the correct time. Please, don't forget to screw the crown back.Adjusting the date.The Vostok watch does not have a “Quick Set” date system, however, you can adjust the date faster. Set the crown to position 3, move the hands just past midnight (00 hrs.), then backward to about 8 pm (20-00 hrs.), and again advance the hands forward past midnight (00 hrs.). The date will change each time the hands advance past midnight.It's important to take care of your watch to ensure it lasts as long as possible. Here are a few tips to keep in mind:- It's important to keep your watch safe and in good condition. To do so, make sure to protect it from any sudden shocks, exposure to chemical products, and magnetic fields. This will help to ensure that your watch lasts as long as possible and continues to keep accurate time. Be sure to handle it with care and store it in a safe place when not in use;- To prevent the glass from getting misted over, it's important to make sure that the crown is screwed on tightly. So be sure to check the crown regularly and tighten it up as needed to prevent any fogging or misting.- Remember to always check that the crown is screwed in tightly before submerging your watch in water. This will help prevent water damage and ensure that your watch continues to function properly.SHIPPINGYour item will be carefully packed and dispatched from New Castle, Delaware, USA within 48 hours (Mon.-Fri.) of receiving payment.International buyers, please keep in mind that import duties, import taxes, and charges are not included in the item price, and will be the responsibility of the buyer.Thank you for your purchase!
