Seiko has released two new solar radio chronographs from the Seiko Brightz series at a suggested retail price of 105,000 yen each (including tax).
The Seiko Brightz Solar radio-controlled chronograph receives standard radio waves that transmit highly accurate time signal with an error of only 1 second per 100,000 years, and maintains precise time. In addition, since it is a solar type that converts light (including sunlight and fluorescent lamp light) into electric energy and drives it, regular battery replacement is not required.
Both SAGA051 and SAGA053 models feature stainless steel cases. The 43.4mm diameter case is enhanced with a beautiful luster by applying “Zaratsu polishing. Both versions have black pinstripe pattern dials featuring three counters (seconds, chronograph 60 minute and 24-H) and a date window at 4.30H.
The movement used in the Brightz Solar Radio Chronograph is Seiko Caliber 8B82. The small sub-dial positioned at 9 o’ clock has a small-hand for displaying multiple functions. Firstly, it displays the second. It also indicates the energy level of the solar cell of the watch with its varying revolution. It moves at one-second interval when the watch has sufficient charge.
Whenever the energy depletion forewarning function is activated, the second hand will move slowly (at two-second or five-second intervals). As soon as the watch switches over to power save function, the hand will stop rotating. This hand also displays radio wave reception level when the manual reception mode is activated.
The chronograph function can be used immediately as it does not require complicated operations like mode switching. If you press the start button at 2 o’clock, the stopwatch will start measuring immediately. The watch has a central chronograph hand for 1/5 second measurement and a sub-counter at 6 o’clock for 60 minutes. It allows a maximum measurement up to 6 hours. The Seiko SAGA051 Brightz Solar Radio Chronograph version has a pink chapter ring on the chronograph 60 minutes register.
For second time-zone function, the watch features a 24-H sub-dial at 3 o’clock. The Brightz Solar Radio Chronograph is equipped with a “time difference correction function” that allows you to move only the hour-hand to set the local time without stopping the watch.
This timepiece is magnetically resistant (JIS magnetically resistant watch type 1). In addition, in the unlikely event that the hands shift due to an external impact, the automatic hand position correction function rectifies the hands to the correct position every minute for the second hand and every 12 hours for the hour and minute hands.
