Citizen automatic chronograph 67-9631


Citizen had two automatic calibres.

One automatic chronograph is the 8110A and you can read about the “octagon bullhead” that had this movement here:

And the other one is the one I will write about now, the 8100A.

Both of them came with different case design, shapes and sizes with a lot of dials. This is why sometimes is difficult to identify if a certain watch is correct or “reconditioned” with aftermarket parts.

vintage citizen automatic chronograph 8100

This is a one sub-dial design chronograph featuring a lot of interesting details. It was made in November 1973.

The case is made of brushed and polished stainless steel. The chronograph pushers are on the side, where the winding crown is. It is a cushion shape with a circular grain brushed front surface (I have seen a sunburst grain also, and polished – the polished is for sure not correct) and polished everywhere else. The caseback is screw in with a circular brushed flat surface. The crown is signed “CTZ”. The mineral crystal sits a little bit taller than the case, with chamfer edge. Nothing out of the ordinary, jut a simple, normal ’70’s design by Citizen, 38mm wide without the crown.

The dial is blue with orange and silver accents. It is nothing less but gorgeous! The blue changes from dark blue (almost black sometimes) to bright blue and then to a type of green really difficult to picture. Sometimes it seems unreal. You have to see one in real life in order to fully appreciate the beauty of this one. On 6 it is the sub-dial, counting the elapsed (30) minutes. This is the only sub-dial (normal for cal 8100A). The central, orange central sweeping hand counts the seconds. This sub-dial is silver with highlighted 5 minutes periods. The 5-10 minutes is blue. Not only the chronograph hands are orange but also the current time hands are painted (not entirely) orange and they have a luminous line. On 3 o’clock there are the day and the date windows, with a silver painted frame. The days and the dates are printed on black disks. The polished Citizen logo is applied and so are the hour markers. The hour markers have an orange central line ending with a luminous dot. On the outer side of the dial there is a white Tachymeter scale, for racing, you know!

The movement is the Citizen automatic, 23 jewls,  calibre 8100A with hand winding capability. It was produced by Citizen starting from 1972, just as 8110A. It is a vertical clutch chronograph (beating at 28.800 bph) with column wheel and fly back function. It also features a day and date indicator. The fly back function means that you can reset the chronograph while in motion and it will start again without needing to go the entire process of pressing stop-reset-start. So, one push can do all of this. Of course  that if you want to stop it you can go the classic stop-reset way. A particularity for this movement is that when you want to change the day you should pull the crown to second position (for changing the date) and push and release the reset (5 o’clock) button. It is 27 mm wide and 5,8mm high, (1mm less than 8110A). The column wheel/vertical clutch design of the movement advices to leave the chronograph running for most of the time (this way you can also see the beautiful sweeping central second hand in movement), but from time to time it should be stopped. This is a chronograph that needs to be used. It is not made for design purpose but for timing.

The bracelet is an usual one piece link design, made by Citizen, with a brushed surface that suits the watch perfectly. It is made in stainless steel with a signed “Citizen” clasp. As usual, Citizen bracelets are very comfortable with a lot of adjustments so finding the perfect fit is easy.

Conclusion: Wonderful Citizen chronograph, vintage yet so modern, with a nice wrist presence and amazing dial!

Citizen “bullhead” Chronograph 67-9356


This is one of the best vintage chronographs that i can think of! 

Of course you could say that a vintage “Paul Newman” Rolex Daytona is way better, but let’s take a look at this beautiful timepiece.

 

This is THE vintage automatic Citizen chronograph, Challenge Timer, also known as bullhead, Easter rabbit or Mikey Mouse – due to its particular shape. It was first introduced in 1978. (on the caseback the first digit of the serial shows the year and the next two digits are for the month) The reference number is Citizen 67-9356. Regarding the shape, you can instantly see that this is not like all the other bullheads. This one has a beautiful octagonal shape that gives it personality, masculinity and a lot of  refined power.

The case is made of brushed and polished stainless steel and the case back screws into place. The round bezel is polished and the glass crystal is flat. The shape of the watch is octagonal with the lower part dropping towards the bracelet and the upper part, flat, hosting the crown and two push buttons that operate the chronograph function. The winding crown is a little bit longer than the usual so that it can be operated due to the special case design. It is signed “CTZ”.  Back to the shape of the case: – all the frontal part is brushed, from top to bottom. The top flat surface is also brushed but from side to side. The sides of the watch are mirror polisher reflecting the light in unexpected, beautiful ways. The caseback is also polished. The case alone has on the visible side alone, 21 different surfaces, not counting the bezel, crown and buttons so the visual effect of brushed and polished surfaces, with a lot of angles, gives a powerful feeling.

The dial is classic, with three contrasting subdials positioned at 3, 6 and 9. There are only two types of dial colors for this model – black with white subdials and white with black subdials.  (The metal base round case model has a lot of variation in dial color but for this model we have only black and white.) A lot of “restorations” are with aftermarket dials, so pay attention on this aspect when thinking of buying a Citizen chronograph. The indexes of the dial should be raised but the luminescent dot (green) should be on a lower part of the applied index. The Citizen logo is also applied. The hands are painted to better contrast with the dial. The subdial at 3 counts the elapsed minutes (30), the one at 9 – the hours(12) and for the seconds we have the central hand. The subdial at 6 is for the day and date. The day is in two languages, and sundays are painted red. For the white dial version the day and date wheels are black and for the black dial the wheels are white. This gives them a better integration in the general design. On the outside of the dial we have the classic tachymeter.

The movement is the Citizen automatic, 23 jewels,  calibre 8110A with hand winding capability. It was produced by Citizen starting from 1972. It is a vertical clutch chronograph (beating at 28.800 bph) with column wheel and fly back function. (how many modern chronograph do that, and what is their cost?) Lets don’t forget it has a day and date indicator. The fly back function means that you can reset the chronograph while in motion and it will start again without needing to go the entire process of pressing stop-reset-start. So, one push can do all of this. Of course  that if you want to stop it you can go the classic stop-reset way. A particularity for this movement is that when you want to change the day you should pull the crown to second position (for changing the date) and push and release the reset (1 o’clock) button. It is 27 mm wide and 6.9mm high. The column wheel/vertical clutch design of the movement advices to leave the chronograph running for most of the time (this way you can also see the beautiful sweeping central second hand in movement), but from time to time it should be stopped. This is a chronograph that needs to be used. It is not made for design purpose but for timing.

The bracelet (i saw different models but the one on the black dial in pictures is 100% sure it is original to the watch, and my favorite design for this model) is stainless steel, wider where it connects with the case and narrowing towards the signed “Citizen” stainless steel clasp. Each link is made of only one piece. Pay attention that most of aftermarket bracelet are with full links, the original is made of folded steel.

Conclusion: Beautiful to wear, beautiful to look at, interesting special design, wonderful automatic fly back chronograph movement that needs to be used… what else to ask for a vintage chronograph?

Here are some beautiful pictures of this movement:
