In physical stores, there is a tendency for scratches to occur during trial wear, oxidation under spotlight exposure, etc. Generally, watches are protected with a film.In the watch market, there are hundreds of stickers for a few bucks per pack. To determine if a watch is brand new, it's not about whether there are stickers or not.If a watch has been worn for a few days, it will generate many scratches that cannot be repaired.Our watches are only sold online, there are no issues with physical store sales. They come with a film when leaving the factory; if there isn't a film, it means there isn't one. All products are brand new and genuine, please rest assured to use them. Why is there a color difference in the picture? All products in our store are genuine and we do not sell counterfeit goods.Pictures may vary due to lighting or monitor differences; even the same image can have color variations on different monitors.For example, the white steel strip in the same image may appear white, gray, or even black in different positions.It is recommended that all buyers check the actual product in-store before purchasing. Buyers who cannot accept any color difference or size discrepancy from what they imagined should consider carefully before buying and check the actual product in-store before making a purchase. Why does the watch need a battery change as soon as it's purchased? Explanation 1: The battery of a quartz watch is already installed in the case at the factory, so even if it hasn't been purchased by the customer after leaving the factory, the battery may still wear out. Therefore, it's possible that the customer might need to replace the battery soon after purchase. Explanation 2: When the watch produces the movement, the battery is inserted and it starts running, then it is assembled into a watch. During this process, it goes through various distribution channels, continuously consuming electricity.The watch does not start ticking as soon as the customer decides to buy it; it's natural for the battery to run out in advance.The watch does not have a factory date marked on it, and we are not aware of the time required for intermediate distribution channels. Why is the watch I received not working? Generally, the chronograph hands of a three-eye watch usually don't move except when timing. Just like when our physical education teacher asked us to press start at the starting point and stop at the finishing point during a race, and then calculate the speed based on the distance of 50m meters and the time taken.This pointer refers to the stopwatch function. It operates by pressing a button to start counting time. Normally, there's no need to keep moving it as it consumes more battery power.The small dial among the three eyes that moves every second is the time second hand Why does an automatic mechanical watch still need to be wound? Fully automatic mechanical watches wind themselves through the movement of a gravity hammer inside the watch. However, when the wrist doesn't move enough or the watch hasn't been used for a long time, it's necessary to manually wind it to give the watch enough energy. Why do some automatic watches still have a hand-winding mechanism? This mainly serves two functions: 1) If the wearer of the automatic watch has little activity for the day, especially for some ladies, they can quickly use the winding mechanism on their wrist to wind the watch without difficulty This may cause the watch to stop due to insufficient power. 2) When the automatic mechanism fails and affects winding, you can use manual winding to continue using the watch. What should I do if the watch strap is too long? The watch strap can be adjusted at any watch store for a fee How to adjust the 12-hour calendar? Explanation 1: First adjust the calendar to the previous day, use the hands to move the calendar to the current day, then adjust the time to distinguish between morning and afternoon, so that the calendar does not jump at noon. Explanation 2: 1. Adjust the date to yesterday.2. Then rotate the timeline by 24 hours, adjust the date to today, and then set it to today's time What could be causing the second hand to be misaligned? The hour hand is mounted on the hour wheel tube, and the minute hand is mounted on the minute wheel tube. They are interconnected through a cross-wheel to maintain a fixed transmission ratio. Therefore, when the hour hand is at the hour mark, the minute hand needs to be at the minute mark.The second hand is installed on the second wheel shaft and belongs to the transmission system. It has no direct connection with the minute hand (meaning that when the minute hand points to the hour mark, the second hand may not necessarily point at the 60 mark). All time adjustments can only be made to the hour and minute hands, not the second hand. Even if the second hand is adjusted after the minute hand points to the hour mark, there will still be some inconsistency. In daily life, the minute scale is sufficient and the second scale has no practical significance. Therefore, when assembling the second hand, it can be installed at any position A simpler explanation: This situation is quite normal for regular quartz watches.The problem lies in installing the second hand; it wasn't fully aligned with the dial scale. Even if it were aligned, there is a gap in the second hand transmission gear that causes the second hand to jump out of alignment with the dial scale.But these do not affect the accuracy of the quartz watch moving 60 seconds per minute Is an excessive time deviation in a clock considered a malfunction? Both mechanical watches and quartz watches have corresponding quality standards, and there are certain errors in timekeeping. The accuracy of a watch is relative; an absolutely accurate watch is impossible. However, as long as it meets the timekeeping quality standards of the watch, it is considered a qualified watch. Watches are calibrated according to regulations before leaving the factory. Those that can be calibrated during sales should be calibrated again and sold if they meet the standards. If some are out of tolerance, they should be adjusted and calibrated before sale. Due to different users and conditions, some watches may show deviations after use (i.e., the timekeeping error exceeds the standard), which is a phenomenon that occurs during use and is not considered a malfunction. After adjustment, it can reach normal. However, if the timekeeping error is too large and cannot be adjusted to normal standards, it is considered a performance failure and requires maintenance How to correctly adjust the date and time 1. Please do not adjust the date between 22:00 and 2:00 (some watches between 20:00 and 4:00), as this can easily cause damage to the watch and incorrect calendar jumps. 2. In order to extend the lifespan of the watch, many watches use a slow jump method, which means they gradually advance around midnight. Generally, it is normal for the jump to be completed by 2 AM, and some watches complete it by 4 AM. 3. If you notice that the calendar jumps during the day, you can adjust it --- If you find that the calendar jumps around noon during the day, it's usually because the watch time is off by 12 hours. For example, if it's actually 11 a.m., but the watch shows 11 p.m. of the previous day, you just need to turn the watch's hour hand one full circle to change from afternoon to morning. 4.One Generally, when adjusting the time on a watch, you need to turn it clockwise, not counterclockwise.Counterclockwise winding can easily cause deviation in the watch's needle direction (quartz two-hand type should be wound counterclockwise). 5. Different watch styles require different adjustment methods, but when adjusting watches with a calendar function, factors such as morning and afternoon need to be considered. Why does a watch that is waterproof still get water inside? The waterproof test of watches is usually conducted under normal temperature pressure tests. Therefore, in daily life, try to avoid using them in environments with large temperature changes and humidity.The waterproof components of the watch are composed of metal and non-metal materials.At normal temperature, they work well together. However, when encountering environments with large temperature differences, due to the different coefficients of thermal expansion and contraction of the two materials, their deformation amounts are also different.At this time, there might be issues with coordination.If you encounter soapy water with a higher permeability at the same time, water will enter.After returning to normal temperature, the waterproof components will resume their function and continue to be waterproof.But the water has already entered and cannot be drained out anymore.Once moisture enters the watch during use, it needs to be cleaned and maintained at a professional repair center or dehumidified with waterproofing What should be noted when using waterproof watches? (1) Waterproof rubber rings are prone to aging and deterioration, so they should be replaced regularly or during each repair. (2) Damage to the watch glass can affect the waterproof performance of the watch, so it should be replaced promptly if it becomes damaged. (3) Do not operate the watch crown in water or when the watch is wet to prevent water from entering the watch movement. (4) After using the handle, push it to the end. Make sure to tighten the screw lock handle onto the watch without leaving any gaps. (5) If the watch gets wet, wipe it dry immediately. (6) Prevent chemical substances from contacting the watch, as this can affect the watch case and waterproof gasket, reducing its performance. (7) Do not leave the watch in high temperatures for extended periods (over 60 degrees)℃) and low temperature (-10℃In the environment. (8) If there are water mist spots inside the watch, they should be promptly removed to prevent rusting of the mechanical parts.
