subject: Review Of Seiko Premier Kinetic Perpetual Calendar Snp001 Snp001p Snp001p1 [print this page] Seiko premier watch SNP001 is an analogue quartz watch equipped with the Kinetic technology developed by Seiko. It generates the electric energy by using the movement of your body to charge the watch. This energy stored in the rechargeable battery which requires no periodical replacement unlike conventional button-type batteries. When the watch senses 24 hours of inactivity it puts itself into suspended animation (sleep mode) to conserve energy. In a sleep mode also the date continues to advance correctly. Wake it up with a few shakes of your wrist and it automatically resets itself to the correct time even if its been asleep for up to 4 years.
This watch has a Power save function and time relay function. In order to conserve the stored electrical energy, the watch automatically enters power save mode to stop the hands from moving approximately 24 hours after the watch is taken off the wrist. When you decide to wear the watch again, simply swinging the watch several times will awaken it and the hands will indicate the correct time to resume normal operation.
Its a amazing Seiko perpetual calendar watch Once set, the calendar automatically adjusts for odd and even months including February of leap years. It takes approximately two seconds for the calendar to change its display. However, it may take two minutes if the temperature is low or the stored electrical energy is being depleted. While the watch is in power save mode, the perpetual calendar continues to function. Even if the watch is completely stopped due to a shortage of stored electrical energy, the calendar can be manually adjusted by simple procedures.
Power Save Function This watch is powered by electrical energy generated and stored by the built-in Kinetic System. The watch also features the power save function, which automatically stops the hands from moving when the watch is not in use for a certain period of time to minimize the electrical energy consumption. When the watch is in power save mode, the hands stop moving but the built-in IC continues to calculate the time and calendar. When the watch is in power save mode, swinging the watch several times will activate the time relay function, which automatically resets the watch hands to the correct time that has been retained inside the watch.
Time Relay Function When the watch is in power save mode, the hands stop moving but the built-in IC continues to calculate the time. When a certain amount of electrical power is generated, the watch hands are adjusted automatically to the time retained inside the watch. The operable time of the time relay function varies depending on the electrical energy stored inside the watch. In a case that the fully charged watch enters the power save mode, the time relay function of the watch remains operable for approximately four years.
