Also known as UFO, Seiko 5 Sport 6119-6400 is a large watch with a strong 1970s feel.
Its stainless steel case resembles a UFO. I don't believe it was polished.
The orange dial is excellent. 
Crystal shows scratches, some significant, and is a bit foggy. It might need to be polished or replaced.
I don't know its service history. Please assume it will need service.
It sets and runs well. Setting the date involves pushing the crown in. It does set, but you have to push hard.
Timekeeping accuracy is good, not more than few min +/- day.
Dimensions: the case is approx 43 mm. Lugs are 20mm.
It comes with its original stainless steel marked band, which also shows scratches.
I purchased this watch few years back. I used few times since then. Selling it as I accumulated too many of them.
