I know most of you old timers (excuse pun) wear a half hunter in your waistcoat pocket and check it by the grandfather clock in the hall so perhaps you should look away now… And you Wenchy...
I was looking into watches today – I love watches and have loads but there is always room for just one more…
I was looking at the Seiko web site and was drawn to their Kinetic range (I have one already). Kinetic means that a moving weight charges a little battery which drives the watch – like a traditional ‘automatic’ watch but no springs and stuff...
Check out the specification on the latest Kinetic Perpetual tho!
The Kinetic Perpetual combines the beauty of a classic mechanical perpetual calendar, correct until February 28, 2100, with the advantage of Kinetic – no battery change, perpetual quartz accuracy, and up to 4 years autonomy when not worn.
The Kinetic Perpetual is a triumph of classical watch-making and modern microelectronics. With 232 parts, which is almost the same number as other high-class mechanical chronograph watches, and the world's smallest ultra-sonic motor, just 0.4 mm thick, the Kinetic Perpetual caliber sets a new standard in Perpetual Calendar watches. This 0.4 mm thick ultra-sonic motor is the only motive energy for the 101 parts in the mechanical gear trains of the Perpetual Calendar which correctly displays not only date and day, but also months, including February in a leap year. This remarkable calendar is also checked by a photo sensor. This sensor recognizes a certain mark on each gear and judges, and corrects, the date, day, month and year; including February in a leap year.
The caliber also incorporates SEIKO's unique Kinetic Auto-Relay technology. No battery change is ever required, and yet Kinetic Perpetual offers quartz accuracy and reliability. With Auto-Relay, the watch will, when not worn for 24 hours, go into "sleep" mode for up to four years. The accuracy remains and the calendar continues to show the correct date, month and year, but the hands stop, conserving energy, until, once the watch is put on again, the hands automatically reset to the correct time.
SourceSo you put the thing on after four years and it resets itself, time, date and everything!
