This review is from: Seiko Premier #SPB007 Men's Self Winding Automatic Watch (Made in Japan) (Watch)

Accuracy:

This watch is Caliber 6R15B, not 6R20 (posting says both). I think the beats are about 23000 not 28800.

It is highly accurate though, at least the one I got was.

The most it ever lost or gained in a day was 5 seconds. Typically it's no more than a second or two off per day. It runs fast and slow, so it's not uncommon for me to only lose a total of a second or two in a week.

Physical Characteristics:

This is a large watch, thick, wide and heavy.

The stainless is highly polished. Combined with the silver dial and large size, this watch definitely could be considered "bling".

You can't see much through the case back, but I guess you can at least tell it's mechanical. No big deal since that is the part facing my wrist.

Opinion:

I was mostly looking for an accurate mechanical watch. I am very happy with this watch. I've had it for over a month now and have only set the time ONCE. It's currently 5 seconds fast.

I wish it were thinner, lighter and not so wide, but it does make an visual impact as jewelery because of its size.
