Out of curiosity, is the bezel made out sapphire crystal? The reflection is like glass.
This is some facts but I don't think the bezel is made from sapphire glass just a gloss finish. This may not be scratch resistant.
From Seiko site:-
"As a special specification limited model only, using a sapphire glass to glass that covers the dial, we have to improve the durability. It also is a testament of the limited edition "LIMITED EDITION" and the serial number is marked on the back cover.
? orientation of the back cover, the fact and may be different.

Enkidu: Thanks for the compliment. But there is a deficiency in the dial, the minute marker as it is not align and it is well known now at the 12 o'clock.
Even when I purchased this from Chino the ad disclaim this fact. A let down for the lower range Seiko
The dial is better looking than the original Sumo as it does not make it look so huge with the stick hour marker as compared to round marker which could made it looks rounder and fatter.
