Seiko Automatic Diver SKX419K Stainless Steel, Cal. 7S26
are the numbers "2" of the double digit days. I checked with other models, the number "2" always seems to be missing the lower left corner for the 20 plus number of days. I am not sure whether this is intended or a consistent quality problem. I noticed the same thing on all my Seiko divers. Also different for this watch is the chrome SEIKO logo with the connected letters. The other divers have the name SEIKO printed on the dial.
