Caliber 0100 lineup as of Nov 2023 from this Citizen webpage
. . .

Because many of the models are Japan only, I think it's more useful to keep track using the main Citizen Japan website's "The Citizen" page. Unfortunately, they do delete information as the models change, so for archival info, etc., you often have to use the Internet Archive Wayback Machine & other means to find the archived pages.

 

Super find. Thanks for sharing.

 

For completeness, the classical mechanical Caliber 0200/0210 lineup as of Nov 2023, but this will not be updated as my focus in on the HAQ lines:

(2021, The First model) NC0200-90E in ss, black grained dial, no date

(2022) NC0206-18E "Japanese Armor" in ss, zirconia ceramic bezel, hammered effect black dial, no date, Himeji Kurozan leather strap, LE of 90

(2023) NC0207-07A, ss, zirconia ceramic bezel, white dial, no date, Himeji Kurozan leather strap, LE of 200

NC1000-51E, ss, black grained dial, date

NC1001-58A, ss, white grained dial, date

NC0200-81L, ss, blue sunburst dial, no date, "LE"

 

Citizen's HAQs are the spiritual successors to a 1960's accuracy-focused line of Chrono Master (with a space) models, as detailed in this web page .

(image from thesamuraivintage.com)

I will slowly work backwards from the latest-gen time & perpetual calendar HAQ caliber A060, which is Citizen's mainline offering (not the dateless caliber 0100).

 

Additional Caliber 0100 model, seen here: AQ6032-03P, 18kyg case, "Tosa Seichō paper"「土佐清帳紙」 dial, display back, LE of 50.

(movement-case ref 0100-T027709 back 0100-T041022 or 0100-T04102z dial)
Model number would suggest membership in the first AQ60xx series.

 

AQ410x models powered by caliber A060

AQ4100-06W Ti, green paper dial, 38.3 x 12.2 mm*
AQ4100-14L Ti, aqua paper dial, 38.3 x 12.2 mm*
AQ4100-22E Ti, grey dial, 38.3 x 12.x mm*
(movement-case ref A060-T027369)

AQ4100-57A Ti, white dial, 38.3 x 12.2 mm
AQ4100-57L Ti, blue dial, 38.3 x 12.2 mm
(movement-case ref A060-T027369, same as above three)

AQ4100-65W Ti, Pt on white washi dial, 38.3 x 12.2 mm, LE of 500
(movement-case ref A060-A1CT403)

AQ4102-01X Ti duratect gold, brown dial, 38.3 x 12.2 mm*
(movement-case ref A060-T027610)

AQ4103-16E Ti duratect gold, gold on black washi dial, 38.3 x 12.2 mm*, LE of 350
(movement-case ref A060-A1CT402)

 

AQ4103-16E Ti duratect gold

Hands-On: Citizen "The Citizen" AQ4103-16E Watch With Tosa Washi Sunago-Maki Paper Dial

 

AQ409x models powered by caliber A060, generally released in 2022.

AQ4090-59E Ti, complex dark dial, 40.0 x 12.2 mm, LE of 400
(movement-case ref A060-T027041)

AQ4091-56A Ti, white dial, 40.0 x12.2 mm
AQ4091-56E Ti, black dial, 40.0 x12.2 mm
AQ4091-56L Ti, blue dial, 40.0 x12.2 mm
(movement case ref A060-T027351)

AQ4091-56M Ti, indigo washi dial, 40.0 x12.2 mm
(movement case ref A060-T027351)

This generation is the largest that The Citizen got - out to 40.0 mm stated diameter. The subsequent AQ410x models shrank to 38.3mm, while stated thickness remained 12.2 mm.

 

I’m sure they are great and well made but like many Citizen watches if find them soulless and boring

 

Soulless and boring? Please elaborate so those of us that do not may be enlightened.

 

Observation: AQ410x series debuted a new case shape. Compare the lugs. The AQ410x case seems to be following the caliber 0100 AQ6xxx case style inspired by the facets of a quartz crystal.

Also, the downsizing from the AQ409x series was accomplished by shrinking the horizontal size of the angled rehaut.

 

Thanks for the share. I wish they'd release a GMT model.

 

I hear you. As a consolation, the caliber 0100, A060 and A010 do have quickset hours, meaning you can adjust the hour hand forward and backwards in whole hours without affecting the timekeeping.

 

I love Chronomasters, but $16,800 for the 06A is ridiculous.

 

Is that what they are going for? Jeeezzzzz

It's got a very, shall we say familiar family resemblance...

 

^^^ White gold, ultra limited, halo piece. I get it.

 

Yes, different, but familiar.

Nice looking watch, I really like it, but pricing is insane.

 

AQ408x series. I can't find any besides these 3 steel models

AQ4080-52A ss, silver dial, 37.2 x 10.2 mm
AQ4080-52E ss, black dial, 37.2 x 10.2 mm
AQ4080-52L ss, blue dial, 37.2 x 10.2 mm
(movement-case ref A060-T026907 engraved on casebacks)

(For ordinary dials, I won't bother tracking down photos of each color.)

 

AQ407x series

AQ4070-05A Ti, Pt on washi dial, 38.3 x 12.2 mm*, LE of 350 (in 2020 for 25th anniversary of The Citizen)
(A060-T026486)

This LE uses the 'new case' design with angular lugs that later appeared in the regular production AQ410x watches.

Besides the above lone model, I can find no other watches by internet search, save a passing WUS mention by @Domo of "the AQ4070, which was previously only available in a gold-toned DLC coating" which might refer to a different A060-powered watch such as the AQ4042-01P, not a AQ407x model.

 

Anyone familiar with my posts knows im a GS fanboy but if I ever bought another HAQ it'd be a The Citizen hands down. I think they look great.
They went through a dark period IMO when they lost all their branding and most had the PR meter on them (no offense, just not for me) but now they're using the eagle-looking critter which I like, or adding "Chronomaster" back on the dial and signing the crowns, coupled with the clear technical superiority of the 0100 movement, it's a no brainer for me

Speaking of the eagle, there was a change for the better from AQ405x to AQ406x , looking much less like a chicken

Also, some history of the meaning from an old post: the 'Eagle Mark' widely spreading feathers as a symbol of confidence and pride for Citizen's watch making was engraved. Only The CITIZEN is allowed to embrace Eagle Mark now. The letters of Eagle Mark and Chronomaster are proofs of pursuing high precision by enthusiasm as in those days, a symbol of self-confidence and pride."

 

AQ406x series

AQ4060-50A ss, champagne dial, 40.0 x 10.1 mm
AQ4060-50E ss, black dial, 40.0 x 10.1 mm
(movement-case ref A060-T026443)

AQ4060-50W ss, 'white butterfly' dial, 40.0 x 10.1 mm, LE of 300
(movement-case ref A060-T026443)

Citizen seemed to be releasing steel and titanium series alternately during this time, with duratect steel priced lower. These steel watches at 10.1 are slightly thinner than their titanium contemporaries at 12.2 mm.

As mentioned above, the AQ406x series debuted a revised and simplified 'eagle' medallion on the caseback.

 

AQ405x series (end of 2019 press release)

AQ4050-02L 'Blue Eagle' ss, blue dial, 39.0 x 11.6 mm*, LE of 300
(A060-T025846)

AQ4054-01E 'Black Eagle' ss dlc, striped black dial, 39.0 x 11.6 mm*, LE of 300
(A060-T025854)

These feature the older 'eagle' logo both on the dial and casebacks. The Black Eagle's caseback is also DLC-coated.

 

AQ404x series (end of 2018 press release)

AQ4040-06A Ti, silver dial with special inlaid indices and matching hands, 38.3 x 12.2 mm*, LE of 300
(A060-T024866)

AQ4041-54A Ti, champagne dial, 38.3 x 12.2 mm
(A060-T037432 on dial only)
AQ4041-54L Ti, blue dial, 38.3 x 12.2 mm
(A060-T037441 on dial only)

Below is a special model released in 2020 for the 25th anniversary of The Citizen
AQ4042-01P Ti duratect gold, gold leaf on washi dial, inlaid indices, LE of 500
(A060-T025978)

Note new case shape, but old 'eagles' front and back

 

AQ403x series

AQ4030-51A Ti, white dial, 40 x 12.5 mm
AQ4030-51E Ti, black dial, 40 x 12.5 mm
AQ4030-51L Ti, blue dial, 40 x 12.5 mm
(movement-case ref A060-T024271)

Note no eagles on the dial. That apparently resumed with the AQ4040-06A LE. 'Chronomaster' in cursive.

(caseback shot of -51A from this WUS member review)

 

AQ403x series

AQ4030-51A Ti, white dial, 40 x 12.5 mm
AQ4030-51E Ti, black dial, 40 x 12.5 mm
AQ4030-51L Ti, blue dial, 40 x 12.5 mm

(caseback shot of -51A from this WUS member review)

Two bits about the 4030…still had the detailed, complex eagle on the back… once the new models got the eagle on the dial, the eagle logo is now simplified and less intricate. Also, I have seen varying opinions whether this model used alpha titanium. I can tell you my metal is all but scratch free as I approach 2 years of wear with pretty hard use.

 

@Mandaue — rookie question (since I’ve zero experience with Eco-Drive) — when it says Eco-drive is it confirmed it’s solar?
thanks.

 

when it says Eco-drive is it confirmed it’s solar?

Yes, I believe that to be the case. 'Eco-Drive' = photovoltaic capability. Counting from the 1976 Crystron Solar Cell, Citizen marked the 40th anniversary in 2016 with of course a bunch of LE watches, including a JDM Exceed (ref AQ5000-13A), but that is a story for another day.

 

AQ402x series

AQ4020-03A Ti, white paper dial, 37.5 x 10.6 mm*
AQ4020-03E Ti, black paper dial, 37.5 x 10.6 mm*
(A060-T023207)

AQ4020-54W Ti, red 'Jounetsu' grid dial, 37.5 x 10.6 mm, LE of 400
(A060-T023207)

AQ4020-54X Ti, green “Shenpeki” (深碧) washi dial, 37.5 x 10.6 mm, LE of 200
AQ4020-54Z Ti, red “Shinku” (深紅) washi dial, 37.5 x 10.6 mm, LE of 200
(A060-T025421)

AQ4020-54Y Ti, white washi dial, 37.5 x 10.6 mm
(A060-T023207)

Perhaps due to some marketing effort at the time (2019) or perhaps in the afterglow of Citizen's 2018 centennial and/or the 2019 launch of the caliber 0100, the above three watches were reviewed by Time and Tide and Revolution.

(below added 11/6)

AQ4021-51W Ti, white "tosa unryuu" washi dial, 37.5 x 10.6 mm*, LE of 300, supplied with both bracelet and strap
(A060-T025234)

AQ4024-53Y Ti with gold plated bezel, washi dial, 37.5 x 10.6 mm
(A060-T023215)

 

AQ401x series does not seem to exist

AQ400x series being the inaugural watches of Citizen's new A060 movement which dropped the generally unpopular power reserve subdial, got some special dials

AQ4000-51A ss, champagne sunburst dial, 38.5 x 10.1 mm

AQ4000-51L ss, black pinstripe dial, 38.5 x 10.1 mm

AQ4000-51L ss, blue fume dial, 38.5 x 10.1 mm

All ss cases were 'duratect' surface hardened. Note neither 'Chronomaster' nor eagle emblem on the dial. The crowns are also unsigned. All three models movement-case ref A060-T021417.

-51A and -51L photos from Gnomon Watches listing and review

(added later)
AQ4001-08A ss, eagle patterned white dial, 38.5 x 10.1 mm*, LE of 200 for 20th anniv of The Citizen (PR 2016/11)
(A060-T022839)

Barring additional discovered models, this concludes the caliber A060 models up to present day. Next: caliber A010.

 

I love everything denim so for me the indigo dial version is most attractive. But I hope the indigo dial is somehow treated as it's light fastness properties aren't great.

Your concern deserves more study. Citizen do address UV in general, but is that enough?

That AQ6110-10L is both the only non-LE caliber 0100 with strap and the only non-LE with display back. Having handled a Ti first series in the metal, I can tell you that the brushing is unbelievably even

 

Thanks for memorializing all of these models, @Mandaue, it's an interesting look back at a still underappeciated series from Citizen.

I can take or leave the eagle/chicken, but I LOVE the Chronomaster script on these. I hope it makes a return in future releases.

Thanks for the encouragement. I like to know the full range of choices when I shop.
