	== Two-piece case era (1936–1944) ==		== Two-piece case era (1936–1944) ==

	~~In 1936~~ Rolex ~~simplified the~~ Bubbleback case ~~from the first-generation four~~-~~piece architecture to the two-piece form that carried through the rest of~~ the ~~line~~. Cal. 620 (subsidiary seconds) and Cal. 630 (sweep seconds) became the dominant automatic calibers, developed by Emile Borer at Aegler.		Rolex introduced a two-piece Bubbleback case with refs. 3131 and 3132 in 1936. Other references still appear in catalogues as three-body cases, including the 3134. Cal. 620 (subsidiary seconds) and Cal. 630 (sweep seconds) became the dominant automatic calibers, developed by Emile Borer at Aegler.
