Keks provides a historical overview of the Seiko 5719 chronograph, contextualizing its release during the 1964 Tokyo Olympics and Japan's post-war economic resurgence. The author shares insights into the watch's technical features and personal connection to this significant vintage reference.

The sixties was a hugely transformative decade in Japan. After World War 2 ended in 1945 many parts of the country had been destroyed and a nationwide effort to rebuild started taking place. By the time the sixties came Japan had emerged as a first world economic engine. Hosting the Olympics in 1964 was not an insignificant effort for a nation still busy rebuilding itself while building on its world class industry powers. 

Seiko was named the official timer at the Olympic Games but they did not have any previous sports timing experience. Ambitious development programs commenced in 1961 and various divisions were delegated various tasks. Some of the items needed were large timing devices, stop watches, electronic timing devices, etc. Some new technology included a timing device that started by the sound of the starter gun and stopped from the touch of pads at the end of the swimming pool. Additionally photo finish was used at the goal line to determine questionable outcomes in various races. 

Seiko wanted to release wristwatches with complications at the games to demonstrate its technical capabilities. The first ever Seiko GMT (ref. 6217-7000) and first ever chronograph (ref. 5719) were released. (Note: in the 40s Seiko supplied military forces with a chronograph model but this was not commercially available). 

The 5719 was a mechanical mono pusher chronograph with a power reserve of 38 hours with the chronograph running. Initial batch was fitted with luminous hands and a plastic bezel which was replaced shortly thereafter by a metallic bezel. I have heard of bakelite bezels being used as well but not seen one myself. The plastic bezels proved to be too fragile and metallic bezels were used instead. Dial color options were white or black with white being by far the more common. Case measures 38.2mm excluding the crown, 11.2mm thick and lug width is 18mm. 

I managed to acquire a 5719 a few years ago in a configuration that I was looking for. White dial, dauphine hands without lume, metal bezel. To me personally the most aestetically appealing combo but there are many cool versions. It certainly feels a bit like a time capsule wearing this timepiece. Takes me on a mental journey back to 1964 even though it was many years before I was born.  

Interesting are the two ads below, one from the United States and one domestic Japan. Note the chronograph is listed at USD 29.45 in the US and JPY 8,500 in Japan at the time which makes sense given that is roughly were the exchange rate was back then.... 








Thanks for looking. Ending with a pic of mine:

I was very close to buying a 6217 World timer last year since I thought it might make a great pair with my 5217. However after trying it on numerous times I had to conclude it was not for me. The colors made it too retro I suppose, at least in a way where I did not see myself wearing it. In the end that is a major criteria for me when considering a timepiece. But when I google the 6217 I do find it very photogenic..... hmmm....

I 100% relate to your sentiment of being transported back to a different time when wearing these pieces. And like you this was well before I was born too, and in a land far far away (although, by coincidence, I am sitting in Tokyo as I write this!). Here's one of my time capsules, also featured in the original advertising, the World Timer. The picture is a little old, but the background is (aptly) Tokyo!

Sharing mine bought new when visiting Changi, Singapore in 1969 (manufactured September 1968). Many of my colleagues did the same in 1960's and the coloured dials were very fashionable then. The Seiko 5 was very accurate, which also made them popular. Best Clive

thanks for your lovely picture of the world timer. It is such beauty. Particularly the font of the cities are pure time travel to me. Interestingly they chose two non cities. One I can understand as there is probably no better way describe the time zone, however the other does have a capital city.... but perhaps a space issue? Yours looks like it is in amazing condition with the original bracelet at that! Again thanks for sharing!

Very cool blue dial. Never seen this before. I have no doubt wearing this brings out plenty of memories of things going on during the last five decades. Thanks for sharing this very amazing piece!
