Λογικό να αντιγράφουν τον γεννήτορα της κατηγορίας. Όπως, πολύ σωστά έγραψε και ο ggli, τα χαρακτηριστικά μετράνε.

Ετσι και ετσι..
Τετοιου ειδους ρολογια δεν μου πολυαρεσουν.
Φαινετε ποιοτικο ομως οπως μας εχει συνηθισει η εταιρεια.

The secret behind Citizen Eco-Drive technology

Producing energy from light may eventually provide sufficient power for our daytime domestic and Industrial energy needs, but for watch enthusiasts, the demands of powering quartz timepieces has long been solvable by simply harnessing the light from our star.
Eco-Drive technology



The modern variation of Eco-Drive technology has been embedded in most Citizen Watches since 1995, although earlier varieties of the technology were first seen in the 1970’s and indeed even made it in to a series of children’s watches featuring cartoon characters during the mid-1980’s.
Eco-Drive watches




Most Eco-Drive type watches are equipped with a rechargeable battery known in the trade as secondary battery. This is due to their ability to reverse their electrochemical reactions to store new power. The basic technology in use in the charging system is rarely of watches is similar to that found in domestic battery charge.
The battery type in use is constructed from a mix of titanium and lithium ions. An amorphous silicon solar cell that is located behind the dial delivers the charge to the battery. The mix of metals in the battery protects it to a large degree from ‘memory effect’ where the continual charging and discharging of the battery causes a battery to lose capacity.
Lithium batteries



Batteries removed after a 10-year lifecycle from damaged watches have still been found to be able to hold around 80% of their optimum charge. As a fully charged battery can run with no further charging for around 30 days, a loss of 20% is unlikely to have a significant effect on the day-to-day wearer of the watch.
There are many movements used in watch making and few are manufactured in house. In the case of Citizen watches the timepieces are usually fitted with Japanese made movements from the company’s Miyota subsidiary.
In common with most user-powered timepieces, these watches go in to hibernation mode when they sense that their power supply is nearing its end. This enables the timepiece to conserve its power for its internal quartz mechanism rather than exerting this power on using the hands to display the time. Before entering the power saving mode, Citizen Watches will also switch to a mode where it moves the second hand every other second to indicate the problem of low charge.
It is not just the time keeping functions that can be operated from the rechargeable battery. Many models include chronographs; with other models, offering radio controlled atomic timekeeping. In those instances a small radio receiver is found nestled inside the watch and this is used to pick up the Long Wave signals of the time signal stations. This receiver is powered from the same battery and charging system as the rest of the movement.
Through the years, Citizen Watches have tried other methods of power generation, including exploiting the thermal difference between the air temperature and the body temperature of the wearer. The watch was unpopular with consumers and later withdrawn.
With few other methods of power generation for quartz watches, the Eco-Drive will be around for a number of years yet.

Φοβερο το eco drive,αλλα ακομη να βρω ενα Citizen που να με ''τρελλανει'' οπως η Seiko!

επειδή φοράς τα ρολόγια στον δεξί καρπό...αλλιώς το autozilla θα ήταν εδώ και καιρό στα αγαπημένα

Το Autozilla ανεκαθεν μου αρεσε!
Και σιγουρα θα γινει συλλεκτικο στο μελλον.
Βεβαια ειναι λιγο ''δυσκολο'' ρολοι,αλλα ειναι ρολογαρα.
Αλλα ρε φιλε ενα-δυο ειναι τα Citizen,η Seiko εχει ολοκληρο ''στρατο''.Για να μη βαλουμε και τα βινταζ,εκει χανεται η μπαλα...

[stavros_ch]

Συμφωνω απολυτα με το Θοδωρη.
Πολυ καλη η Citizen το εχω πει πολλες φορες ειναι η εταιρεια που με εκανε να ασχοληθω με τα ρολογια.
Η Seiko ομως ειναι αλλιως.. Ειδικα στα divers ειναι απιστευτη.
Οσο για τα βινταζ λεφτα και ορεξη να εχεις!

Του citizen γινεται.......
