It refers to a Seamaster fitted in the reference 2990 case, that of the Ranchero, and combines the names Seamaster and Ranchero. Launched in 1958, the Ranchero line sold poorly and was discontinued around 1960. Original examples with the Ranchero name on the dial are even rarer today. Seacheros, for their part, are seldom seen.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails style=\"border-bottom: 1px solid #ddd; padding: 10px 0;\"\u003e\n\u003csummary style=\"cursor: pointer;
