you guys might want to talk to zoodles. IIRC he bought a feiko very similar to this one and wrote a fairly extensive article pointing out all the failings of the feiko. IIRC they had copied even the movement, but not very well.
BTW, unless the angle is funny, the crown on this thing seems to be at 0400. If it is a real 007, the crown should be at 0345.
Looking at the wear on the case and crystal, I'd say that the watch was at least 10 years old (or it's spent it's life in a cement mixer) - were they making fake Seikos back then?
One thing that did concern me was that the bezel appears to be plated, not solid stainless. The case is solid stainless. The bezel click spring is a curved piece of wire located into a hole in the case, running from about 10:00 to 07:00, IIRC.
The crystal is hard mineral glass - took me ages to polish it.
The stem has some kind of universal/wobbly fitting hidden inside the crown. The stem is screwed in tight, but can rock slightly relative to the crown.
The seller listed it as needing attention. The minute hand was fouling the seconds hand, so maybe someone had fitted replacements. The dial may be a replacement, too, as it shows no sign of ageing.
After a strip and clean, it's keeping very good time (10 seconds a day), and it winds perfectly.
