The 6150 sits at the very start of the Explorer lineage. It is closely related to references 6098 and 6298 in case construction and general specification. The Vintage Rolex Field Manual says the 6150 evolved into the 6298/6350 in 1953, with the transition bringing 3-6-9 Arabic dials and Mercedes hands. It is succeeded by the 6350, which takes the same A296 calibre, certifies it to COSC standard, and puts ~~“Explorer”~~ on every dial.

* '''Predecessors / siblings:''' 6098, 6298

The Vintage Rolex Field Manual documents several additional Explorer-adjacent references from the same era that share the 36mm case and chronometer ambitions: the 6298 (Cal. 1030 and A296, stainless steel), the 6299 (Cal. A296, stainless or yellow gold — notably a steel/yellow gold variant), the 8044 (Cal. 1030, stainless), the 8045 (Cal. 1030, gold fill), and the 1427 (Cal. 3000, stainless). These are not Explorers by name, but they document how wide Rolex's exploration of this 36mm tool-watch niche was in the early 1950s.

Total production volume is unknown under either timeline. The Vintage Rolex Field Manual notes that the 6150 evolved into the 6298/6350 in 1953, which could mean the 6150 continued in production alongside its successors rather than being replaced cleanly.

The 6150 runs calibre A296, the same base movement that appears in the 6350. The critical difference is certification: the A296 in the 6150 is ~~'''~~not~~'''~~ COSC-certified, making the 6150 a non-chronometer watch. This is the single clearest technical distinction between the 6150 and the 6350. It is also the key distinguishing feature from the 6610, which uses calibre 1030 .
