The Citizen Tsuyosa Automatic Watch NJ0150-81X is designed for consistent and reliable timekeeping. Its automatic movement means that as long as you wear it regularly, your natural arm movements will keep it wound and running accurately. This makes it a convenient choice for daily wear, removing the hassle of battery replacements.
The sapphire glass provides exceptional protection against scratches from everyday bumps and scrapes, maintaining the watch's pristine appearance over time. This is particularly beneficial for those with active lifestyles or desk jobs where accidental contact is common. The luminous hands and numbers are a practical feature, especially useful when checking the time in dimly lit environments, such as a movie theater or at night.
With its 40 mm case diameter and silver stainless steel finish, the watch strikes a balance between a noticeable presence and comfortable wearability. The green dial adds a distinctive touch, allowing it to stand out subtly whether you're at the office, a social event, or simply running errands. The date calendar function offers a quick reference for the day, enhancing its utility. Its 5 ATM water resistance rating confirms its suitability for daily life, handling splashes and light rain with ease, making it a reliable companion for most urban and casual settings.
Unboxing: Carefully remove the watch from its original gift box. Inspect for any transit damage.
Initial Winding (if stopped): If the watch has stopped, gently turn the crown clockwise about 20-30 times. This provides an initial power reserve to start the movement.
Setting the Time: Pull the crown out to the furthest position. Turn the crown to adjust the hour and minute hands to the correct time. Ensure you distinguish between AM and PM when setting the date.
Setting the Date: Push the crown in one step from the outermost position. Turn the crown to set the correct date. Avoid adjusting the date between 9 PM and 3 AM as this can damage the movement during the date change mechanism cycle. Set the date to the previous day, then advance the time past midnight to automatically roll to the correct date. This ensures the date changes at noon, not midnight.
Securing the Crown: Push the crown fully back into the case to ensure water resistance and to start the watch.
This watch is designed for standard wrist wear. The 21 mm wide stainless steel bracelet is adjustable to fit most wrist sizes up to 21 cm in circumference. Professional adjustment by removing links may be required for optimal fit.
Cleaning: Wipe the watch regularly with a soft, dry, lint-free cloth to remove dirt, sweat, and oils. For the stainless steel components, a slightly damp cloth can be used, followed by a dry one. Avoid harsh chemicals or abrasive materials.
Water Resistance: The 5 ATM (50 meters/165 feet) rating means the watch is resistant to splashes, rain, and brief immersion. Do not operate the crown or pushers underwater. Avoid wearing it while showering, swimming, diving, or engaging in water sports, as steam, hot water, or direct water pressure can compromise the seals.
Magnetic Fields: Keep the watch away from strong magnetic fields (e.g., speakers, MRI machines, strong magnets), as these can affect the accuracy of the automatic movement.
Impacts: While durable, avoid dropping the watch or subjecting it to severe impacts, which can damage the internal mechanism or crystal.
Servicing: Automatic watches benefit from periodic professional servicing (typically every 3-5 years) to ensure lubrication, seal integrity, and overall accuracy. Refer to the warranty information for authorized service centers.
Storage: When not wearing the watch, store it in its original box or a watch box to protect it from dust and scratches. If you don't wear it for several days, it will stop and need to be reset when you wear it again; a watch winder can keep it running if preferred.
