I would say you nailed it Ken - Sea King "B" it is. Good find on the ad, great looking watch.
Regarding the two date codes. When they're within a year we generally accept the latest. The assumption being that this watch was assembled early in the year using a movement from late '62 and a case from early '63. The same would be true if the case was '62 and the movement was '63. When the gap is greater than a year a movement replacement is more likely.
