Changsha 长沙 17J


Model : Changsha (长沙)
Manufacturer : Changsha Clock and Watch Factory (长沙钟表厂)
Year of Production: ??
Case Diameter : 
Weight w/o strap: g 
Movement Model : Standard Movement ZCS (17 jewels) 
Type : Hand Wind 

This is a watch by Changsha Clock and Watch Factory (长沙钟表厂)in Hunan (湖南) Province and Changsa (长沙) is the capital city of Hunan Province. Hu (湖) means lake and Nan (南) means south; it means south side of the lake: Lake Dongting (洞庭湖). There, at the north side of the lake, is Hubei (湖北)province; Bei (北) means north. My Hubei watch is here.

The other line of watch produced by Changsha Clock and Watch Factory was Youyi (友谊), meaning "friendship".

Changsha's logo is made up of "C" and "S" overlapped and superimposed onto each other and the idea of which, unlike other vintage watches, is quite contemporary.The hands of the watch are special and this is the only watch with such hands in my collection. It would definitely impress people if the hands were given a new lume.

Changsha watches were initially powered by Shanghai movement SS1, like the onse used in Shanghai 1120 watch, and later by this standard movement. Below the balance wheel is the code: Changsha logo with 312. I am not able to figure out the year of production from this code.

Shanghai 上海 A-581


Model : A-581
Manufacturer : Shanghai Watch Factory (上海手表厂)
Year of Production: 1962 
Case Diameter : 
Weight w/o strap: g 
Movement Model : A-581 (17 jewels) 
Type : Hand Wind

This Shanghai A-581 is my second watch in Shanghai 581 series. The first 581 is Shanghai A581 (the post is here; also see the same post for more information about Shanghai 581 series). The difference between the two models is the "-" between the "A" and "581". This A-581 has all the six authentic features of Shanghai 581 as outlined in the  post. 

The caseback is engraved with "QUAN GANG" (全钢) which literally means all stainless steel, i.e. both the watch case and the caseback are in stainless steel. A-581 with this caseback is the first full stainless steel watch in the series.

Ascertaining the time of production of this Shanghai A-581:
  • the caseback of type #6 of this post of micmicmor website and according to the post it should be produced in 1962 - 1963;
  • the Zuan (jewel) in Chinese had been in simple form "占“ until about 1964; this watch has "占“ printed on it;
  • it has a date code of 6210A under its balance wheel which means the first batch of production in October 1962;
  • the balance wheel is not screw compensated; it was screw compensated in earlier Shanghai 581. According to the micmicmor's post this improved movement should be produced from about 1964.
There date code is inconsistent with the first three bullet points. If micmicmor's post on the compensated balance wheel is correct, this balance wheel could have been replaced by previous owner although I think it is quite unlikely to be the case.

This watch in its original form is as below:


I stumbled upon the 581 dial in taobao.com which was, according to the seller, a NOS (I believe it is a remake rather than a NOS) and replaced that 'overly cleaned' old dial with this new face. Voilà,  its glorious days are restored!

Shanghai 上海 114 The First Chinese Military Watch (Reissue) 114 中国第一军表(复刻版)




Model : 114 The First Chinese Military Watch (Reissue) 114 中国第一军表 (复刻版)
Manufacturer : Shanghai Watch Factory
Year of Production: 2009
Case Diameter : 
Weight w/o strap: g 
Movement Model : DG2813 (22jewels) 
Type : Automatic

Like the first Chinese air force chronograph 1963, this first Chinese military watch 114 has also become prized by the collectors of vintage Chinese watches. This piece of mine is a reissue by Shanghai Watch Factory.

The genesis of this watch began in late 1960s. In 1969, the Central Military Committee of China appointed Shanghai Watch Factory to commence production of this watch specifically for the People's Liberation Army. The model number was 114. The 114s were powered by 29 jewel SS2 initially and later by 24 J SS4 automatic movements; the one with SS2 movement was for high-ranking military personnel while with SS4 was for mid-ranking and lower. The watches were not free issued that the military personnel would have to fork out their own money to buy one and the price was 240 yuan.

There were several batches of trial productions with 29J SS2 movement between 1967 and 1969 and after which the production proper commenced. The 29J SS2 watch was produced   till some time in 1970. [Some said its production ceased earlier in 1969. I believed it ceased in 1970 as I saw images of 29J in the internet with serial number of 7000948 and A7001215]  The rotor of 29 J SS2 movement had the inscription of "29 ZHAN GUNZHU ZIDONG" (29 占滚珠自动, 29 jewels ball bearing automatic). Note that it was not 'ZUAN' (钻) but 'ZHAN' (占) despite its dial used 'ZUAN'.

The dial was embossed with "中国制造 29钻" above 6 hour index and there was no logo below 12 hour index. However, embossed characters only appeared in early production; they were printed on in later batches. The crown was like the reissue's which was a hemisphere crown without logo. The watch had luminous hands, indices and bezel markings.The luminescence in greenish white was actually radium paint which was a known radioactive material. But the quantity in a wristwatch was too small to be harmful.  The bezel shape was the one of this reissue. 

The caseback was inscribed with 5,6 or 7 digits. The first two digits were the year of production and the following digits were the product serial number in that year. One should see 67XXX, 67XXXX, 68XXXX, 69XXXX,  70XXXXX and A70XXXXX.

Some time in 1970, the production of 114 with 24J SS4 movement started. It featured anti-shock,anti-magnetic and waterproof. It had a screw down crown signed with logo  but smaller and flatter.It was indeed a military diver watch. The movement had the inscription of "SS4" on its bridge board followed by either a single letter or two letters. Its rotor was signed with "QUAN ZIDONG 24 ZUAN" (全自动24 钻,all automatic 24 jewels) and in later version the rotor was not signed with anything at all. The watch looked quite like the 29J SS2 with a few obvious differences in that, other than the crown, it had the "Shanghai 上海" logo below 12 hour index, unpainted second hand and coin edge bezel.  Like the 29J SS2, this watch too had serial numbered on its caseback but in 7 or 8 digits, i.e. A70XXXXX, A71XXXXX, 71XXXXX, 73XXXXXX and 74XXXXX.


Some time before or in 1973, the watch was re-branded as torch "火炬" brand. The "Shanghai 上海" logo on the dial was changed to red torch "火炬" logo and too the signed crown. The price known then was 180 yuan, somehow lower than that in earlier years.  The production ceased in 1976 (some said in 1977) and altogether there had been approximately 30,000 pieces of 114 made. Given that 7129XXX has already surfaced and the production had not stopped until 1976/77, I think 30,000 pieces is a conservative estimate.

Initiatives have been taken by some of the members of China based fora i.e. watchlead.com and iwatch365 (as listed in the 'Links' page of this blog) in gathering the serial numbers. The above knowledge in regard to serial number is from all the relevant threads in the fora and the contribution of the members is hereby acknowledged and the effort of the initiating members is appreciated. There are some observations on the serial numbers gathered: there has been no 72XXXXX, 75XXXXX and 76XXXXX reported so far, it may be just a matter of time the numbers will show up; the denotation of pre-fix 'A' in some of the watches in year 1970 and 1971 has been unknown and remained a mystery. 

Turning to this reissue, it is powered by 22 jewel DG2813 movement, a movement not by Shanghai but Dixmont-Guangzhou Watch Factory.  It is said in the iconic Alberta Museum of Chinese Horology in Peace River  that
[It] contains a 22 jewel Dixmont-Guangzhou 2813 auto movement. Interestingly, the DG 2813 movement, although only 22 jewels, is actually closer to the original SS4 watch movement specs than anything Shanghai currently produces... (link here)
Except "Shanghai 上海“ logo below the 12 hour index, the bezel, the crown and the hands are copy of 29J SS2 watch. The 29J SS2 is different from 24J SS4 in that it has straight edge bezel (not coin edge), red second hand, shorter stretch of lume on the hour and minute hands and hemisphere signed crown. Therefore, it is very much a 29J SS2 than 24J SS4 reissue.

All the above information were from various unofficial internet websites and fora and therefore unverified with records nor supported with any evidence.

Tianjin 天津 ST19 The First Chinese Air Force Chronograph 1963 (Reissue) 中国空军第一只航空码表1963(复刻版)




Model : The First Chinese Air Force Chronograph 1963 (Reissue) 中国空军第一只航空码表1963(复刻版)
Manufacturer : Tianjin Watch Factory 天津手表厂
Year of Production: 2010 (December)
Case Diameter : 
Weight w/o strap: g 
Movement Model : ST1901 (21 jewels) 
Type : Hand Wind

This is a reissue of the first chronograph for the Chinese Air Force, one of the most popular watches collected by the Chinese watch enthusiasts. 

There is an article in Tianjin Watch Factory website on this chronograph (the link is here). The article wrote that although a chronograph was a necessity for the air force personnel, in term of watch ownership, they were no different from civilians in that watch acquisition was a private matter and one would have to buy his own. Watches were mainly imported as the domestic watch industry was still at its infancy. The PRC government then decided to appoint a domestic watch factory to develop a chronograph that it would not only cut down its dependency on import but would also accelerate the growth of the domestic industry. At that time, there were only two factories which were more established, i.e. Tianjin Watch Factory and Shanghai Watch Factory.   Tianjin Watch Factory was finally chosen by the government appointed as it was the factory producing the first Chinese watch  'Wuyi' (see my 'Wuyi' here but not the first version) and, compared with Shanghai Watch Factory, it was nearer to Beijing being the administrative centre of the PRC. That decision was made in April 1961 and the project number was '304'.

Half a year later, 5 pieces of prototype were produced. At the end of 1963,  a second batch of 30 plus pieces of prototype were made.  In 1965, a further batch of 100 plus pieces of prototype were completed and it was finally sanctioned for production in December 1965. The movement was named as 'ST3'. In May 1966, Tianjin Watch Factory commenced the production proper and lasted till 1969. There had been about 3,000 pieces chronographs made in the period.

As this reissue is for chronograph '1963', the design probably takes after the second batch of prototype made in 1963. 

Inside this reissue is a ST19, a movement  developed from ST3 in 2002. According to wiki, it was based on Swiss Venus 175  the  tool-set of which were purchased by China for this chronograph project. This following information from wiki is interesting:
Venus 175 - A hand-winding movement with column-wheel controlled chronograph with 30 minute totalizer, no hour totalizer. Production ceased in the early 1960s.
Strictly speaking, the Sea-Gull ST19 is not a 'clone' of the Venus 175, as it is descended directly from a movement built on the same tool-set as the original Venus, transfered to the Tianjin Watch Factory in the 1960s for production of a watch exclusively for the Chinese air force. This ancient design was resurrected in the 21st century, and subtly but extensively upgraded to become the ST19. Due to its use in fake Omega Speedmasters, it is occasionally (and very incorrectly) referred to as a 'Lemania clone'.
From time to time, luxury Swiss watches are offered featuring refurbished vintage Swiss movements, including the Venus 175, however examples have emerged where Swiss companies have used the ST19 and claimed to use a vintage 175. Any such watch featuring more than 19 jewels and an escapement 'upgraded' to 21,600bph should be assumed to be a mis-labelled Sea-Gull ST19. 
Venus 175 had 17 jewels and the improved version, ST3, used in the original chronograph had 19 jewels. The modern ST19 has 23 jewels in Sea-Gull branded watches or 21 jewels  in this reissue by Tsinlien Sea-Gull Hong Kong (see the threads from Watchuseek forum on the on the jewel count here and here). Although there are actually 21 jewels, '19 Zuan' is printed on the dial; this is probably intended to be as closed as the original dial which used '19 Zuan'. Some of the earlier reissues were printed as '21 Zuan'.

Other than the above '19 Zuan' / '21 Zuan' print variants in the reissues, there are other variants among the batches churned out in different time periods both within China and outside China. The variants are: red  or clear (not filled with red paint) star logo,  acrylic or sapphire crystal (built in different bezel), sapphire or stainless steel solid caseback and signed or unsigned crown. There is also another 'variant', this 1963 has had the second hand and minute counter's hand incorrectly swapped at the sub dials. 

In 2007, the remake was issued by Tsinlien Sea-Gull Hong Kong as limited edition (limited to 208 pieces) for mainly China's domestic market. The limited edition had serial numbered stainless steel caseback. The number format was "NO. XXX/208 HK". The watch had a clear star logo, '19 Zuan' on the dial, unsigned crown, strap buckle signed with the star logo and  movement signed with "AIR FORCE 304".

This 1963 reissue is, too, from Tsinlien Sea-Gull Hong Kong. The imprint of "中國空軍第一表複刻版 (1963)" on the box cover can tell that as they are in traditional Chinese characters with which Hong Kong people are more familiar; it would have been "中国空军第一只航空码表复刻版 (1963)" in simplified Chinese if issued from the mainland.

[Added on 9 January 2011]
These are two images of air force chronograph that can be found in the internet that claim to be the first chronograph. Sea-Gull from the PRC rolled out a reissue in 2010 for the right image. The left image is probably the 1963 version and the right is 1966 version.

[End for addition on 9 January 2011]

Tianjin 天津 ST5 Dongfeng 东风 (East Wind) - Green


Model : Dongfeng 东风 (East Wind)
Manufacturer : Tianjin Watch Factory 天津手表厂
Year of Production: 1970s
Case Diameter : 
Weight w/o strap: g 
Movement Model : ST5A (19 jewels) 
Type : Hand Wind

This is a green dial Dongfeng watch. Dongfeng movement signed with ST5 is a fast beater 21600bph and whereas the one signed with "东风” is a lower beat movement 18000bph. This is the second fast beat Dongfeng in my collection. They are exactly the same except that this Dongfeng is a black dial with green color at the centre. However, unlike the first Dongfeng, there is no anti-magnetic shield inside; not sure whether it has been lost before reaching my hands or has not been included originally.
