Citizen had three calibers for their alarm watches. The first one, and probably one of the most beautiful timepieces, is this little part of history. Watches powered by this movement were made around 1960. The first one seems to have come out in 1958? making it the first one of a long successful series of alarm watches.
The case is gold filled and has an elegant look, with beautifully shaped lugs and well chosen crowns. Speaking of the crowns, the lower one sets the time and winds the movement. The upper one is for setting the alarm and winds it as well. This is the same for all Citizen alarms. The entire case is polished except for the snap on stainless steel case back that has a central circular brushed surface. The case back can be placed only in a certain position so that the hammer of the movement could strike the pin attached on it. In fact this is how the alarm works. (To hear a Citizen alarm, click this LINK) I like the way the inside of the case back is finished and engraved. The strap is black, original too, and the buckle is, as expected, gold plated (filled?).
The dial is made out of two parts, one central disk that rotates and has a red triangle that is the alarm pointer and the outer part that actually has two concentric shades due to the way it was finished. The hands and the applied hour markers are gold to complete this beautiful look. There is not much text on it except for “Citizen Alarm” and “19 jewels Phynox” and in the lower part “Japan”.
The movement is the most important part of the watch and the reason why this watch is a real success, the first Citizen alarm movement. It is the manual wind Citizen calibre 980, 19 jewels, 3 adj, 18,000 bph. Very beautiful and working like a champ.
The blue central disk watch above has a special case-back, made of two connecting layers, the top part having 6 holes and the entire piece acts like a resonance chamber so the sound of the alarm is really, really loud!
update: another version I found online is this one, black dial with contrasting off-white central disk. Notice the red and blue writing on the dial! Beautiful! The case is gold plated. Bottom line, it is a gorgeous watch with a wonderful movement, a real time capsule and one of the most important watches Citizen made. Every collector should have one.
