Citizen Sharex Quartz Ref. 3630-361865 TA
In the 1980s, Citizen produced numerous distinctive designs that combined the slim profile enabled by quartz technology with the era's sharp geometric aesthetics and integrated bracelet style. The Sharex Ref. 3630-361865 TA is a lesser-known yet highly characterful example from this period.

The rectangular case and the wide-linked bracelet are designed to appear almost as a single, unified body. The brushed gold-tone surfaces of the case flow seamlessly into the bracelet's horizontal blocks, while a slender, polished bezel frames the dark dial. The "BASE METAL YP" inscription on the case back indicates the period-specific code Citizen used for this case plating, while the reference number 3630-361865 TA clearly identifies the case and movement family.
The watch's visual character is defined by its dark, near-black, micro-textured dial. While the surface appears solid at first glance, a repeating small geometric pattern reveals itself as light draws closer. Applied gold-tone baton indices and slender hands create a strong contrast without overpowering the texture. A stylized emblem positioned above the 6 o'clock marker links the model to Citizen’s Sharex family.
Inside, the watch is powered by Citizen’s Calibre 3630 quartz movement. In keeping with Citizen’s quartz philosophy of the era, the technology is not displayed on the dial side; instead, the slim movement serves as an unseen foundation, enabling the case's low-profile and seamless geometry.
One of the finest details of this particular piece is its original Japanese sales tag, which has been preserved alongside the watch. The label still bears the inscriptions "Quartz" (クオ-ツ) and "Sharex" (シャレックス), along with the sales code SRM51-9363 YP and the original list price of ¥28,000. Thus, not only the watch's reference number but also a part of its commercial identity from the time of sale has been preserved to the present day.
The original Citizen integrated bracelet and the Citizen-signed folding clasp have also been preserved with the watch. While the case, bracelet, and clasp show signs of wear consistent with the watch's age, the character of the brushed surfaces, the case geometry, and-in particular-the textured dial remain in excellent condition.
The serial number "5O045479" on the case back clarifies the watch's production date. In Citizen’s coding system from that era, the first digit indicates the last digit of the production year, and the second character indicates the month; here, "5" signifies 1985, and the letter "O" stands for October. Thanks to this coding-which aligns with the production period of the Calibre 3630-we can determine that this Sharex was manufactured in October 1985.
Final Thoughts
In 1980s quartz watches, technology was often invisible; it worked to enable the design. In this Sharex, the dark textured dial, the integrated gold-tone bracelet, and the original ¥28,000 price tag still tell the story of that era together.
