i found a Seiko Seiko 1/100 model 7T59 ,the so called Olympic Chronograph ,it was the worlds first analog 1/100 in perfect condition.
It belonged to my father who like Seiko Chronographs and was passionate with timing instruments and chronos .
The semi gold version like bellow :

From what i read they are very rare and only a few were made and Seiko made them only to prove at the Barcelona Olympics that it can be done.
History here :http://www.chezrossi.net/seiko7t59/presentation.html
What is the value of such watch ,i was thinking of selling it,its a remarkable tech marvel but its around 40mm ,which is very small for me ,otherwise i would keepit ,these dont come often around.
Any tips ?
