This was one of the last years (1971) that Citizen used the term “parawater”. Unfortunately it came to an end and this particular model was one of the last parawater divers. It marked the end on an era. What can I say, I just love this Seven Star – Vintage Citizen Diver!
Update 2018 April:
Kim, aka WVE from The Seiko and Citizen watch forum, was king enough to let me use his pic so you can enjoy them. Thanks Kim, lovely collection you have there! 😉 Blue, Silver, Orange and Black dial!
The case is the well known Citizen cushion shape having a diameter of 44 mm without the crown. It is made in stainless steel and so is the caseback and the bidirectional frictional type bezel. The bezel insert is aluminum? painted black with white numbers and markers. At 12 there is a luminous dot inside an upside down triangle. The entire case is polished, except for the frontal surface that has a circular brushed finish. The acrylic crystal is raised and flat. I love the way the light bounces back from underneath an acrylic crystal! The water resistance is 100m, maybe because the signed CTZ crown is a non screw in type. But… 100m is plenty for normal use.
The dial is made from two distinct pieces, glued together; an outer ring is sitting higher than the dial itself and has hourly numerals from 13 to 24. A silver ring delimitates the two surfaces and has minute markers. The lower part has raised polished hour markers with luminous material. The spade shape hands have luminous centers as well. By contrast, the second hand is simple, entirely polished. At 3 o’clock the watch has the day and date display inside a polished frame that connects the two parts of the dial. The usual Citizen logo is at 12 and at 6 it reads: “para 100m water, automatic, 21 jewels”.
The movement is the 7270 calibre – simple, reliable, automatic with 21 jewels and beating at 21,600bph. As usual with Citizen, the automatic movement can be hand winded. It has jewel bearings for barrel and a power reserve of 41 hours. It features a quick set date and the day changes from advancing from 20 to 0:30. The sweeping second hand doesn’t hack.
The bracelet is a common Citizen design called bead of rice that fits the case shape really nice. I have seen other designs (see the cool one on my NOS APSS-52904 Y below) but a lot watches found today have nato replacements or rubber straps. Certain leather straps look good on it too. It is easy to find a bracelet or a strap because it has 20mm between the lugs and a look that makes it easy to wear on anything.
Update 2018 April:
It seems that the models above are export models since the domestic ones, for Japan market, are marked “Seven Star APSS-52904 Y” and have a slightly different dial. I managed to find a NOS one and here it is, also side by side with the orange export version. The case back is also different, and so is the winding crown. Take a look.
And side by side:
Conclusion: Beautiful watch, warm, colorful and full of life. One of the last “parawater” divers made. A real joy to wear and look at.
