Citizen Parawater Jet Autodater ADRS51301-DA





In 1959, Citizen introduced the first water-resistant watch from a Japanese standpoint, elegantly named the "Parawater." This term eventually gave way to the more straightforward "water-resistant" in the early 1970s. Citizen showcased the watch's capabilities by tethering it to buoys in the Sea of Japan. This innovative leap from buoys to creating dive watches swiftly followed. 


The Citizen Jet Autodater 120m embodies typical dive watch features: A rotating graduated bezel with a luminous pip at 12 o'clock, bold luminous hour markers on a beautiful matte black dial, and luminous hands with black tips.


This unique reference lacks serial numbers, making accurate dating impossible. Powered by the intriguing Citizen Calibre 1120 Jet movement (1962-1965), it suggests that Citizen's initial dive watch might predate Seiko's "62MAS."


Now, let's shine a spotlight on the distinguished Cal.1120: Standing at a robust 4.95mm height, its substantial build is attributed to the distinctive rotor employed for automatic winding. Unlike a typical center-pivoted rotor, the Jet movement features an eccentrically weighted ring along its perimeter, smoothly gliding on bearings. This outer ring's inner teeth interlock with a wheel on the movement, efficiently winding the mainspring.


The Citizen Parawater 120m Jet Autodater is a highly coveted rarity, and the one we're offering is not just impeccable but also includes its original bracelet, destined to become a standout favorite on any watch enthusiast's collection.
