Seiko Gen 2 7T27-7A20 1995 British Royal Airforce (RAF) Military Issued chronograph

1995 Seiko Gen 2 (2nd Generation) Royal Air Force 
flight crew issued military analog chronograph

The 1995 Seiko Gen 2 (2nd Generation) Royal Air Force flight crew issued military analog chronograph was issued to Her Majesty’s armed forces from November 1990, following the issue of the Gen 1 quartz chronograph.


The caseback is inscribed with the "broad arrow" and NATO Stock Number (NSN) ‪6645-99 7683056‬ used for military-issued equipment:

6645 = Time Measuring Instruments
99 = NATO Country code United Kingdom
768-3056 = individual part number

In contrast to the commercial versions, the issued version has a 38mm case with a matte, bead-blasted finish, fixed strap bars and a "circle P” dial, indicating radioactive Promethium lume. 

The register at "12" is the 30 minute counter, the register at "6" is the continuous seconds and the register at "9" indicates the current hour on a 24-hour scale. 

The 7T27 (Gen 2) movement takes an SR927SW (395) 9.5 x 2.6mm battery.

Japan: Clocker of the Games Time Magazine, Oct. 16, 1964


The following article appeared in Time Magazine, Oct. 16, 1964 and provides an interesting insight into Seiko production figures in 1963:



"Next to the athletes, the most vital ingredients in the Olympic Games are the precision timepieces needed to clock the contests, whose outcomes sometimes depend on milliseconds of difference. Last week, as the 18th Games got under way in Tokyo, the official timepieces were not European for the first time in Olympics history. They were Japanese, and they all bore one name: Seiko, the brand mark of K. Hattori & Co., Ltd., Japan's biggest watchmaker (1963 sales: $98 million).The switch made sense. Duplicating its efforts in cameras and transistor radios, Japan has quietly become a top producer of watches, aggressively competing around the world against the long-unchallenged watchmakers of Europe. Japanese watch production has ticked upward from 2,000,000 annually to 11,700,000 in a decade, now ranks fourth behind that of Switzerland, Russia and the U.S.Split-Second Timing.

Hattori, founded in 1881 by a clock salesman of that name, started out as a shoestring importer of foreign timepieces, later pioneered Japan's own watch industry. Destroyed by a 1923 earthquake, Hattori rebuilt, only to be leveled again by U.S. bombers. That disaster proved to be a blessing. In starting from scratch the third time, the company virtually scrapped hand-assembly methods, today makes 75% of its watches by machine. As a result of its super-efficiency, Hattori claims to have been for five years the non-Communist world's largest maker of jeweled-lever watches. Last year it turned out 5,900,000 wristwatches, 53% of the Japanese total, this year expects its output to rise to 7,000,000.In 1959, when Tokyo was selected as the 1964 Olympics site, Hattori shrewdly picked a delegation of technicians to attend the 1960 Games in Rome, where they carefully studied timing problems and techniques. When the Tokyo Olympic Organizing Committee asked whether there was a Japanese company capable of providing time clocks for the 1964 Games, for the sake of national honor, Hattori was ready.

Last week, after an investment of $850,000 in research, Hattori's men unveiled 1,300 ingenious Olympic time devices. They ranged from nine varieties of split-second stop watches to an electronic judge of swimming events that: 1) clocks swimmers to 1/1,000th of a second; 2) memorizes individual lap times of up to nine swimmers at a time; and 3) prints all scores on a sheet of paper the instant the race is over, thus eliminating time-consuming human calculation.Pushing the Undersell. For its services Hattori is paid only in prestige. "I hope some of the foreign visitors will remember us after the Olympics," says Company President Shoji Hattori, 64, second son of the late founder.

To refresh their memories, Hattori salesmen are stepping up their export drive, in the past year have broken the Swiss monopoly in Norway, Denmark, and Sweden, where Seiko watches now sell at the rate of 9,000 a month. Another target is the U.S. market, which Hattori has heretofore tapped largely by supplying movements to Benrus. Despite forbidding U.S. tariffs, Hattori is beginning a U.S. sales campaign for Seiko, retailing 17-jewel wristwatches for $29.75, just over half the price of a Swiss equivalent."

1964 Olympic Seiko One-button Chronograph


Been looking for years for a very specific version of the 5719 one button handwind chronograph: the 1964, metal/black bezel, no lume version. Sorta like this one:





Actually, EXACTLY like this one! I'd actually seen this one on the bay and tried a few tentative offers to no avail. Did the same again with a higher offer and - suddenly it was mine!

The price I offered just made my own hair stand up!! But, thinking about it, this is exactly the one I have been looking for, for the last few years - and now I have it! Have seen them go for less, but I have never been around to pull the trigger! So, is it worth what I paid? Actually, yes - as an integral part of a 1964 Seiko collection, I would say its value is greater than as an individual piece. I know I am going to get a lot of bang for the buck doing the researching ;-) I think the caseback may be slightly above average too, and the October 1964 serial number coincides nicely with the October 1964 Tokyo Olympics:


I always factor into the price of my obsession that I - by researching and documenting significant (aren't they all!) vintage Seiko watches  - are paying back some of the knowledge, education and sheer entertainment provided on Seiko and watch forums by members who have paid their "dues" by investing their cash or time. I personally would have a hard time justifying costs if I couldn't share - or receive - the fruits of this obsession!

Here's an interesting piece of information from the Official Report of the Organizing Committee for the Games of the XVIII Olympiad 1964 - 50 Crown Chronographs were presented as Torch Relay gifts. One wonders if they were specially inscribed, or with a special bezel/dial combination - or... perhaps... 5718s?





To those not familiar with the 5717 Crown chronographs, they came in a bewildering variety: black dials / white dials; with/without lume; steel, plastic and steel/insert bezels; date/no-date. I tried once to summarize the different permutations below (please note the 4598 is probably an erroneously typed 45899):

Runners high - on the road with a 1964 Seiko cal. 5717 Olympic Chronograph


Runners high - on the road with a 1964 Seiko cal. 5717 Olympic Chronograph 



The men's marathon was part of the Athletics at the 1964 Summer Olympics program in Tokyo (Wikipedia). It was held on 21 October 1964. 79 athletes from 41 nations entered, with 68 starting and 58 finishing. Abebe Bikila from Ethiopia won the race in a world-record time of 2h12m and became the first athlete in history to win the Olympic marathon twice. Third place went to Kokichi Tsuburaya of Japan (possibly the runner in the Seiko brochure above) in a time of 2h16min. For the occasion of the Tokyo Olympics, Seiko introduced the caliber 5717 One-button chronograph, and almost certainly this chronograph would have been used by spectators to time this race.

On December 3, 2011 Harry, Denmark decided to run 5km against time on a particularly stormy afternoon wearing an almost perfect 1964 caliber 5717 One-button chronograph, although this race would be different: this time, the Seiko was on a non-original bracelet:



Essential to any good run are the right shoes. Not your daughters shoes, or the brown leather shoes you got last Christmas and never wore, but your own favorite running shoes you eventually find under your son's bed:


Properly kitted, the next stage of a successful run usually takes place outside, where you wonder whether it would not in fact be better to get out of the rain and watch some sport on TV instead:





At this stage its worth looking at your watch to see if there is any daylight left, which there unfortunately was. Thus starts the Loneliness of the Overweight Runner. Turn the bezel (the same as on the 62MAS diver) to the minute hand, fire up the iPod and you're off! Exactly 5km later you stop the chrono in a blaze of pain and read off your time - 33m19s:


A new personal record (by 7s) which brings you one step closer to being in reasonable physical form (for a 47-year old). I felt a small tinge of pride as I remembered starting to run regularly a few months ago, and not being able to complete more than a single km without stopping to walk!

Its a great feeling to have a dedicated vintage running watch from your birth year, a Seiko and from the year of the Tokyo Olympics at that! As a collector, I really enjoy using this 47-year old watch for its intended purpose, and having it work as precisely and elegantly as the day it was sold. There is some wear on the caseback, revealing that this watch has been worn and used, while at the same time it has been cared for and appreciated by its original owner. Case lines, dial and brushed finished are pristine, and only the caseback and a few scratches on the bezel indicate that this watch has ever been used:





Finally a shot of two Olympian timekeepers, the 1964 caliber 5717 One-button chronograph and its bigger counterpart, the 1964 caliber 9011 (90ST) 1/10s Olympic stopwatch:

1964 Seiko "Olympic" catalogues



Just in from Yahoo Japan. Its not too often you find Seiko catalogues from the Tokyo Olympic year of 1964, so you have to bait your line when they do appear. Only local Japanese can bid on Yahoo Japan, so I had to get hold of my Japanese "agent" to snag these:









Well, lets see if there is something new in them....







One-button chronograph....nope, got that! How about an Olympic stopwatch then?








Nope...been there, done that. Maybe a dress watch for Christmas, how about a full day/date?








Rats! I got that one too. Well, lets try some high-end "showcase" stuff, maybe Grand Seiko? Or a diver?








Aaargh! I give up! Well, at least I have something to wrap fish in.....
