Dial and Hands
The watch features a classic silver sunburst dial that plays with the light. It is furnished with polished applied baton indices and sharp dauphine hands that provide excellent legibility. A distinctive feature of this reference is the framed day window positioned at the 6 o'clock mark, balanced by a date window at 3 o'clock under a cyclops magnifier. The dial shows signs of vintage character, with visible surface marks and scratches present across the face, particularly near the center and left side, adding to its honest vintage appeal.
Case and Crystal
The stainless steel cushion-shaped case measures a comfortable 37mm and features a striking fluted bezel that gives the watch a substantial and dressy presence. The case lines remain defined, though there are visible scratches and signs of wear throughout the metal surfaces commensurate with its age. The screw-down caseback prominently displays the "Para Water" designation along with the Citizen Auto Dater nomenclature and star logo, all of which are deeply engraved and clearly legible. The crystal features a date magnifier and is in presentable condition.

Powering this timepiece is a Citizen automatic movement with 21 jewels. The rotor is signed and the movement appears clean and well-maintained.

Strap
The watch is fitted with a black leather strap featuring an embossed grain pattern. It pairs elegantly with the silver tones of the case and dial, secured by a silver-tone buckle. The strap is in good condition and ready for immediate wear.

Remarks
This Auto Dater 520 is a charming example of 1960s Citizen design. The combination of the "Para Water" caseback, the specific 520 branding, and the unusual placement of the day complication makes it a collectible piece for enthusiasts of Japanese vintage watches. It offers a wonderful entry point into vintage collecting with a watch that has clearly been worn and enjoyed, yet continues to perform.
History
Citizen, established in 1918, has long been a rival to Seiko in producing high-quality, innovative timepieces. The Auto Dater line was a significant series for the brand in the 1960s, showcasing their capability in manufacturing robust automatic movements with practical calendar complications. The "Para Water" marking on the caseback is historically significant as it was Citizen's terminology for water resistance before the industry standardized nearly a decade later. This specific model dates to 1966, a period when Citizen was rapidly expanding its global influence.
