    Watch functions and handling


    MechanicalQuartz
    power A mechanical wristwatch (self-winding wristwatch and hand-wound wristwatch) is powered by the power to unwind the mainspring, and the general model keeps moving for about 35 to 45 hours. (Varies by manufacturer and model.) Power is a battery. At the time of purchase, the battery for the monitor is about six months to one year. After replacement, the battery runs out in about two to three years, depending on the type of battery.
    Winding crown In the case of a self-winding wristwatch, moving the arm rotates the built-in rotor and winds up the mainspring.If the amount of movement of the arm is small and the winding is insufficient, it may stop or the accuracy may be disrupted, so it is recommended that you wear it on your arm for at least 8 to 10 hours a day.Or we recommend turning the crown once a day at the same time and the same number of times.-
    Durability A mechanical watch with a complicated structure made by meshing many gears has a precise, delicate, and fragile part that is resistant to impact.Examples such as "dropping" and "hitting" are examples of direct impact.However, in some cases, the impact is transmitted indirectly. There are things that come off.(Example: The impact of the ball hitting during a swing such as golf, baseball, or tennis is transmitted to the watch through the arm.)Are better
    accuracy
    (Advance / delay)
    Even mechanical wristwatches equipped with a chronometer have a daily difference of less than -4 seconds to plus 6 seconds.Accuracy also depends on the orientation of the watch when it is worn.This is because gravity and friction between parts affect the operation of the watch.Accuracy also varies with temperature.This is because the metal expands and contracts with changes in temperature.(If it's hot, it's late, if it's cold, it's going) The time accuracy of general quartz watches is about ± 20 seconds per month.
    Magnetic Under the influence of magnetism, the watch can be delayed or advanced, and sometimes stopped, causing time skew.Once a mechanical wrist watch is affected by magnetism, it will always affect its accuracy.In order to be demagnetized, you must send it for repair.At least 5 to 10 cm away from products that generate magnetism, it is almost unaffected.
    <Peripheral magnetic products> Speaker parts of mobile phones, smartphones, portable radios, portable audio devices, notebook PCs / AC adapters / Tablet terminals / Magnet parts of bags, furniture, fittings, etc. / Dryers / Electric razors / Magnetic necklaces / IH cookers ... etc.
    waterproof The waterproof watch has a packing used on the case back, crown and glass to prevent the ingress of moisture and dust from the outside and protect the watch's function.If this packing deteriorates, the waterproof function will be impaired, so periodic replacement is required.
    Please note the following points even with a waterproof watch.
    • Do not operate the crown or chronograph buttons while underwater or wet. Water will penetrate inside.
    • Do not leave with seawater. Be sure to rinse the seawater with fresh water and dry it thoroughly. It may cause rust.
    • Do not use in hot springs. Hot spring ingredients accelerate the damage of metal parts and deterioration of packing.
    • Please refrain from using in the bath / sauna, hot water, soap and shampoo. It will accelerate the deterioration of the packing.
    • Due to the temperature difference between the outside air and the inside of the watch, the moisture originally inside the watch may condense. Temporary clouding does not cause any problems with the watch function.
    * If you think that the watch has been flooded, send it out for repair immediately.
    List of waterproof functions
    Non-waterproof No waterproof treatment is applied. Keep away from water.
    Waterproof everyday
    [ 3 ATM water resistant ]
    Water-resistant depth: 3atm 3bar 100ft (30m)
    Waterproof enough to splash water as expected in everyday life. There is no problem if you are slightly wet with face washing and rain.
    Enhanced waterproofing in everyday life
    [ 5 to 20 ATM water resistant ]
    Water resistance depth: 5atm 5bar 165ft (50m) ~ 20atm 20bar 660ft (200m)
    Waterproof enough to withstand water work-waterproof enough to withstand swimming and swimming.
    Waterproof for diving and saturation diving
    [ Water resistant over 20 bar ]
    Water depth: 20atm 20bar 660ft (200m) or more. Depends on each model
    You can dive in earnest with a watch called "Divers Watch".
    * Periodic waterproofing tests are required to maintain waterproofness.

    What you need to be careful about for a long time with a mechanical watch


    [Date adjustment]
    There are points to note regarding date adjustment.Do not adjust the date between 8pm and 4am the following morning .It depends on the type of movement you have, but first of all you should be concerned with the time above.
    From 8:00 pm to 4:00 the next morning, it is not the real time, but the time on the watch.
    If the watch is pointing to the above time, if you can adjust the time other than above, around 6 o'clock before adjusting the date, there is no problem with date operation.
    The gear that ticks the time and the gear that sends the calendar mesh with each other for four hours before and after the date changes, that is, from 8:00 pm to 4:00 the next morning.
    If artificial force is applied during that time, the internal parts will be overwhelmed, and in the worst case, it will lead to failure.

    [Forgot to lock the screw-down crown]
    After adjusting the time and date, winding the mainspring, etc., always lock the crown while pushing it in.
    If you forget to screw in and water gets inside the machine, it may cause a malfunction.The same goes for divers' watches with waterproof performance.For divers' watches, lock the escape valve as well as the crown.
    Watches with waterproof performance are packed with parts.Since this packing deteriorates over time, regular maintenance is recommended.

    [Fault due to impact]
    The mechanism inside the watch is very precise and very delicate.
    If you give a shock to the watch, such as hitting it strongly or dropping it, it may cause a malfunction.In sports such as baseball, golf and tennis, which use your arms, a very large shock is transmitted to your wristwatch.Be sure to remove it to avoid trouble.

    [Spring out]
    One of the causes of the watch stuck is the mainspring.
    If the mainspring has run out, hold the watch in your hand and shake the watch, the second hand will advance and then reverse rotation for a few seconds.In addition, even if you wind the crown, it will run idle and there will be no response from winding up You.
    Hand-wound and self-winding watches have a stop when winding up the mainspring.Do not wind beyond this stop.
    The mainspring is a consumable item.Even if used correctly, it may be cut by aging.Exchange repair is possible in our shop, please feel free to contact us.
