Seikos 1978-presented Superior ref9983 is not only one of the highest quality Luxury Sport-Steelwatches of this era but for sure the most precise: reason was the 1st use of a digital temperature-compensation by a 2nd quartz (TwinQuartz).

The integrated bracelet with the Royal-Oakish interlinks and the multifaceted case in extra-hardened steel is amazing and wears slim and comfortable.

As Rolex presented its Oysterquartz in the same year a comparison suggests itself and we will do this in our blog soon -- spoiler: the Seiko will not fail on many aspects.
