Citizen Super Ace 23 Jewels 40m

Well, apart from what is written on the dial there is not much info I have about this watch. It is part of the larger Ace family but, of course, it is Super. ūüôā The Super Ace. I date this one around 1966 – 1968 though I have no definitive answer regarding the manufacture date.

First of all I notice the striking aspect of the watch, very modern, and gorgeous on the wist at 38mm diameter. Perfect size, no date, very balanced dial. The entire stainless steel case is polished. The mineral crystal is slightly domed and perfect, with very low unwanted reflections. The dial is a work of art: clean, harmonious, with the applied eagle medallion at 12 and well designed hour markers. The hands are a masterpiece. They have a beautiful shape, made in stainless steel, and are faceted, brushed (on the top part) and beveled, with polished sides and angles. The seconds hand is entirely polished. They remind me of the way Seiko finishes their Grand Seiko, and that is something for such an old watch! The finish of the dial has longitudinal brushed appearance and looks varnished. The elegant printing on the dial is black and it has no luminous material, nor do the hands. This must be one of the best faces Citizen has made!

The caseback is engraved: SACS51301-D, Water Proof, Stainless Steel, and in the middle the profile of a man wearing a helmet (it he a diver, an astronaut or a medieval cavaler… I don’t know and I still have to find out). Either way, this is a rare out of the ordinary caseback. The winding crown is made in stainless steel too and marked CTZ.

The movement is gold plated, manual winding, non hacking seconds, specially adjusted one. It has 23 jewels and is marked Citizen Super Ace. It is the Citizen calibre  SACS 9240? and beats at 18,000bph.

Here it how the papers look like:


Questions to be answered:

  1. when was it made?
  2. what more info are available on the Eagle logo on the dial?
  3. what is the engraving on the back?

All things considered I have to declare this, not the best but definitely one of the best looking vintage Citizen watches. Also wearing it is a joy.

Citizen Chrono Master Autodate 33Jewels

Chrono Master – this says it all.

Chrono Master was, and still is,  the most recognizable high grade line of Citizen,  a real competitor for Grand Seiko and Swiss made watches.

Vintage Citizen Chronomaster

I love the look of this watch, elegant, yet casual, perfect for a suit as well for any daily attire.

The case is made in stainless steel, having what I consider to be a perfect design. The lugs are beautifully designed and every detail shows the great care placed into drawing each line, each angle, each corner. The entire case is polished. The case back has a gold inlay medallion with an engraved eagle. ¬†The winding crown is the right size and shape for the watch, signed “C”. The mineral crystal is flat, sitting higher than the bezel. It’s angled edge makes the dial pop and bends the light is mysterious ways.

The dial is silver, with an sunburst effect. Very clean and organized. The hour markers, the date frame, the Citizen logo and the eagle logo are polished and applied with a lot of care. The details are impressive. There is not much writing on the dial: “Chrono Master”, “Autodate” an “33 Jewels” – this all the information needed to see how this is not an ordinary Citizen. The hands are polished too matching the hour markers, having a longitudinal middle black line.

Citizen 33 jewels cal 5440

The movement is the Citizen calibre automatic 5440 with 33 jewels, beating at 18,000 bph. It can be also with a day (5450) or only date. The number of 33 jewels is high enough but not the highest. Some of these movements are also Chronometers, adjusted to a higher precision. This was possible by the¬†adjuster positioned on the balance. The automatic movement can be winded by hand also. It is a quick set date, and it hack for better time setting. It is a beautifully made movement complimenting the overall design in a fortunate way. The movement print presented here is a part of Stephen’s scans of a Citizen catalogue. His work can be read here.

The strap, in this case, is an aftermarket black snake with a sharp stainless steel custom made buckle. I think this suits the watch very well. I wish I could find an original Citizen buckle of the era but I don’t have high hopes on that.

Conclusion: Beautiful design, wonderful quality, great watch! Every Citizen collection needs a Chrono Master!

Update 2017 September: Here it is a rare blue dial version. Notice the applied logo on 6 and the hands shape. (pictures from the on line seller)
