Another prime example of how well Seiko watches can last, this auto is in very good shape. Model reference 6309-8300.


From the serial number on the case back we can date this watch to being made in October 1978. There is a small chance that the watch was made in 1988, as this movement design was produced between 1976 and 1988, but it is far more likely to have been made in 1978 given the styling.


In October 1978, when this watch was made, the Ford Escort was Britain’s best selling new car. They were everywhere, but now they are sought after and that is a perfect analogy for this Seiko. It too would have been a very popular choice for those who wanted a something good looking and reliable without spending a fortune (but have you seen the price of Mk2 Escorts now!!!). The Seiko has a substantial stainless steel case with screw down case back, and recessed crown. The crown can be recessed as it is not used to wind the watch, as this is only wound by automatic means only. Both day and date can be quick set, and the day can be in either English or Spanish. The dial is clean as are the hands, and everything is running nicely. The bracelet is full length, which is nice and unusual to find. The bracelet has been cleaned in our ultrasonic bath.

This watch will be supplied with our branded presentation box and our Certificate of Authenticity.
