Following the success of the Deluxe model, launched in 1958, Citizen followed up with the Ace (see Featured Watch #5) and the Hi-Line in 1961. The Ace used the 92xx movements as first seen in the Deluxe.  However the Hi-Line used a new movement – the 0500, 0501 and 0502 – which was the same width but was slimmer at 3.25mm rather then 3.65mm.

The Hi-Line completed Citizen’s mid-range hand winding line-up at the start of the 1960’s, and came in 23, 25 and 27 jewel variants. Here’s my 23 jewel example, typically marked Parawater and Parashock, from December 1962:

The back has the trademark scrolling around the markings, which of course include the serial number which provides the production date:

Nice movement although like the Ace it isn’t marked as having ‘adjustments’ as is found on the Deluxe, and runs at18,000 beats per hour:

Based on original retail prices, the Hi-Line was the slightly more expensive of Citizen’s mid-range manual watches, and along with the Deluxe and Ace, offered a good quality and reliable watch.
