Solar powered watch

by David


At last no more winding, with the Citizen Alterna Eco Drive Watch, you need not worry about changing those batteries or winding it up every evening. Solar power has been a long coming to the watch market, and so because of this, the watch will go and go, no longer limited by the battery and it would appear to have some little extras added to make it a watch for life.

Using solar power on a watch does actually appear to be a logical step, though getting the technology right may have been why it has taken so long, this watch from Citizen will charge all of the time in sunlight and in also in artificial light and is accurate because it has a radio control feature which makes sure that the time is correct, no more excuses for being late then! Well not exactly, as this feature may not be available in all countries.

For a watch like this, the attention to detail and the technology is second to none, so why on earth have the put that cover on it with the words “Radio Controlled” across it, this totally spoils the look of the watch.

Specifications – Accuracy +/- 15 seconds/month (typically in single figures), Curved Sapphire Glass, Eco-Drive (Recharged by any light sources, no need to change battery ever), Eco-Drive – 5 years Running Time From Full Charge, Insufficient Charge Warning Function, Date Calendar, Power save, Thickness 10.2mm and Case 40mm.

The watch will cost you $319, quite expensive for just a watch, even though it is solar powered.

Not too keen on the design, concept is OK though. Having said that, my Seiko Kinetics watch has been running for 6+ years without batteries, solar power etc… Works just from the natural movement of the arm during everyday tasks.

I am the owner of a Casio MTG930DA 8V Wave Ceptor Solar Powered Atomic Watch. It very quickly lost all of it’s stored power and has been dead ever since.
Any ideas on how to revive it and keep it charged?

Why is this ‘new’?
I’ve had 2 solar power watches for 3 years now.

Casio makes MANY models.
(And they actually look good.)

Any ideas on how to revive a “dead” Casio MTG930DA 8V Wave Ceptor Solar Powered Atomic Watch after the Solar charge has depleted?

Look for the instructions or call Casio. Try direct sunlight. (Though I suspect your watch is dead.) If dead, it’s repair or replace.
