This one is close to NOS. The edges are still sharp. The dial has not faded. The bracelet matches the case. It has just been serviced.\u003c\/p\u003e\n\u003ch3 dir=\"auto\"\u003e\u003cstrong\u003eWhat CQ meant\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp dir=\"auto\"\u003eSeiko shipped the Astron, the first quartz wristwatch, in December 1969. Citizen did not answer with a copy. It answered with Crystron. The analog Crystron reached the market in the early 1970s — official step-motor models from 1974, rated about ±15 seconds a month, with a seconds-stop and, on some, a small LED at 12. Before that, Citizen’s Cosmotron was still a hybrid: a quartz timer driving a mechanical balance. Crystron dropped the balance.\u003c\/p\u003e\n\u003cp dir=\"auto\"\u003eCQ is Citizen Quartz. By the late 1970s the Crystron name was being folded into CQ on watches people actually bought: steel cases, day-date, water-resist marks, a price above a mechanical Seiko 5 because the technology was still the point. The laboratory piece was the 1975 Crystron Mega, ±3 seconds a year, crystal at 4.19 MHz, priced like a car. This 4-730020TA is not that watch. It is the wearable CQ: Caliber 7300 family, two-jewel quartz, day and date, 10 atm on the dial.\u003c\/p\u003e\n\u003ch3 dir=\"auto\"\u003e\u003cstrong\u003eThis 4-730020TA\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp dir=\"auto\"\u003eRound-square steel, about 35 mm, 18 mm lugs, brushed top, polished bevels. The edges have not been rolled. That is the condition note that matters on a 1970s integrated-style case. The dial is a smoky gradient green — darker at the rim, lighter through the centre — with applied batons and a kanji day beside the date at 3. Water Resist 10 atm is the factory mark. At this age, treat it as a dress-sport watch, not a diver.\u003c\/p\u003e\n\u003cp dir=\"auto\"\u003eThe original Citizen bracelet is in the same state as the case: links tight, brush still there, no stretch. Movement just serviced. Battery timekeeping, not a high-beat tick.\u003c\/p\u003e\n\u003ch3 dir=\"auto\"\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp dir=\"auto\"\u003e\u003cstrong\u003eMaker:\u003c\/strong\u003e Citizen\u003c\/p\u003e\n\u003cp dir=\"auto\"\u003e\u003cstrong\u003eModel:\u003c\/strong\u003e CQ 4-730020TA (Citizen Quartz)\u003c\/p\u003e\n\u003cp dir=\"auto\"\u003e\u003cstrong\u003eEra:\u003c\/strong\u003e around 1977\u003c\/p\u003e\n\u003cp dir=\"auto\"\u003e\u003cstrong\u003eCase:\u003c\/strong\u003e Stainless, angular, edges still sharp, close to NOS\u003c\/p\u003e\n\u003cp dir=\"auto\"\u003e\u003cstrong\u003eCase Diameter:\u003c\/strong\u003e approx. 35 mm\u003c\/p\u003e\n\u003cp dir=\"auto\"\u003e\u003cstrong\u003eLug Width:\u003c\/strong\u003e 18 mm\u003c\/p\u003e\n\u003cp dir=\"auto\"\u003e\u003cstrong\u003eDial:\u003c\/strong\u003e Smoky gradient green, applied batons, kanji day and date at 3, 10 atm mark\u003c\/p\u003e\n\u003cp dir=\"auto\"\u003e\u003cstrong\u003eBracelet:\u003c\/strong\u003e Original Citizen, excellent\u003c\/p\u003e\n\u003cp dir=\"auto\"\u003e\u003cstrong\u003eMovement:\u003c\/strong\u003e Quartz Caliber 7300 family, just serviced\u003c\/p\u003e\n\u003cp dir=\"auto\"\u003e\u003cstrong\u003e\u003cspan style=\"color: rgb(6, 106, 64);\"\u003eA vintage Citizen CQ 4-730020TA in this state is the late-1970s quartz Citizen people skip while hunting Crystron Mega.
