The most precise light-powered watch in the world*
with annual accuracy of ±1 second.
The crystallisation of CITIZEN’s technology,
craftsmanship and philosophy of watchmaking, all refined into the Caliber 0100.


Everything…
powered by nothing but light
Our mission was to keep telling the time with accuracy of ±1 second per year. We achieved this by using light-powered Eco-Drive, a core CITIZEN technology with over 40 years of history. We reduced electricity consumption to power the whole movement—the power-hungry AT cut crystal oscillator, the temperature correction function, the heavy brass second hand—with only light. A single full charge keeps the watch running for eight months.

Seriously cool. As well as seriously Japanese in why it’s cool.

It’s literally a set and forget watch with zero user intervention.

 

$7,400 for the AQ6021-51E (5oo pieces) and AQ6020-53X (200 pieces).

$16,800 for AQ6010-06A in white gold (100 pieces).

I'm a big fan of my Omegas and Rolex watches but my Citizen is the real everyday beater. It's the second one
I've had.....in 40 years

 

My daily beater is a Citizen Airwave Titanium solar powered GPS synchronised timekeeper so I don't really need another almost identical watch (Citizen, solar, well, that's "almost" identical).

But I like the look of it, and appreciate the technology behind it.

But!

FFS!

Who writes the stuff on the website?

"Every second marked by this watch is like a single line of poetry.
There you can discover time in all its profundity: the moment and the eternal; the rigour that forbids even a second’s deviation; a clear borderline between past, present and future; and quality like a finely polished crystal."

"The expression of this watch is one of extreme simplicity: Simplicity that reflects the mechanism’s intention to mark the individual seconds in all their perfect purity."

 

Nice looking piece and obviously super accurate, I've come to admire Citizen.
Acquired this solar model a couple of weeks ago for (I thought) a bargain £70, nicely put together.

Reminds me of a Red Dwarf quote

Kryten:
"Pub." Ah, yes: a meeting place where people attempt to achieve advanced states of mental incompetence by the repeated consumption of fermented vegetable drinks.

 

Pretty cool!

 

I've got 3 Eco-Drive watches and I wore one of them to work and generally abused it every day for over 10 years and it's still going strong. Nothing but respect for the brand

 

This was a pick up same day as the omega f300 pretty cool watch

 

"Tools can be measured by the effectiveness with which they fulfill their purpose. A tool is in good company when it is compared to the hammer; the most effective of all tools at fulfilling its purpose. These classics, these tools that perform a single function and perform it extremely well - so well in fact that there is no tool better for the intended purpose than this tool - these classics are the ones that attract... that stir the heart."

...that's not to say I dislike the watch, i quite like it, rather what I mean is: that it pleases me that there are people who continue to try to improve upon a classic. Call it windmills, call it chairs on the deck, call it what you will. I love finding those examples that make you pause and ask if finally, someone has found a way to "make the thing better".



Edit: whoa, I think the copy @JimInOz posted did something to my brain. What I meant to post was: @STANDY , Red Dwarf? Really? I have *ALL* the episodes. We should have a Red Dwarf and Dark Rum party next time I'm in AU, or you're in CA!

 

Think the episode when Dave is doing the dot to dot and he can’t work it out to he gets the last bit is hilarious

Ahh, a bucket and spade

 

Forgot the pic


This one is a Royal Marines 350 year celebration LTD ED 763/1000

 

Future Echoes was the one that hooked me. 1988. Awesome year for me. I surfed a big wave that year and still managed to swim to shore with no major injuries. That's a metaphor. or is it a simile? analogy? I can never remember.

Edit to add: I'm being ironic (i think. I am, right? *this* is irony? No, wait... Serendipity. It's Serendipituous, right? not ironic. I wish I'd paid more attention in school.)

 

Nice looking watches, pushing the technology envelope. I think they've done a good job.
The brass second hand gets mentioned over & over in the blurb, as if it were harder to achieve than the movt. itself.

 

I'm partial to the black one, but other options available. pretty cool that thermo-compensation is included.

I bet it would look good on smooth black leather.

 

I can see how a 1 sec/yr solar powered watch with no date could truly be a set it and forget it watch. It's always nice to have one like that laying around.

This is where my Atomic controlled Casio Pro-trek Solar, or GPS controlled Seiko Astron Solar come in handy, because I never have to set them as long as I make sure they get enough sunlight to keep on trucking.

I also have a couple of Citizen perpetual calendar ECO-drive chronographs that I don't have to worry about the date as they count the actual month and leap years. But since they gain about 0.3 sec/day (108 sec/yr) I'd still have to hack them for 2 minutes each year to keep them close to atomic time.

 

Thought I was alone in this. Nothing beats an Eco-Drive as a daily wearer. Here’s my super beater (staying true to the vintage vibe)

 

I went through my WatchTracker app. Last time I checked my X-33 it was gaining 4.35 sec/year, and my Grand Seiko SBGX115 was gaining 5.88 sec/year, while my Bulova “Dave Scott” Moonwatch was gaining right at 10 sec/year. Those were all pretty impressive numbers, until this new Citizen watch.

My Citizen Promaster diver is running exactly +4 minutes fast in 807 days, for +108 sec/yr.

PS - my new Pepsi GMT II is losing less than 4 seconds/YEAR based on losing 0.01 sec/day for the past week. Too bad about having to fix it’s date on months with less than 31 days.

My SubC No Date doesn’t have that problem, but it is currently gaining 2.6 minutes/year. So it’s still right up there with the worst quartz watches, but far from 1 sec/year.


.

 

I guess now that ETA matches Citizen's (and Seiko's) long-term 5 sec/yr performance, Citizen just has to issue a new challenge.

Had they made this in SS and charge <= $3,000 USD for it, I might be tempted to trade up my workhorse 10sec/yr Credor for it - just for technology sake ...
