	The sport time-only line opens with the A-series bumper ~~automatics~~. Cal A260 powers the first 6204 and 6205. Cal A296 carries the 6200 and the earliest Explorers, with the 6150 / 6350 split showing the same movement in non-COSC and COSC form. Cal 1030 takes over from 1955 and underpins the mid-1950s Submariner and Explorer generation.

	The 15xx family is Rolex's long middle chapter. Cal 1530 anchors early 5508, 5510, 5512, and 5513 production. Cal 1520 is the non-chronometer twin used in late 5513, 5514, and 5517. Cal 1560 and 1570 carry the chronometer side of the Submariner, GMT-Master, and Explorer lines. Cal 1575 adds the date or GMT module, which is how it lands in the 1680, late 1675, and the 1655 Explorer II.		The 15xx family is Rolex's long middle chapter.

	A specific service-tell deserves naming on Cal. 300: the winding-stem bridge is a known fail point. A Prince that sets time then disengages immediately is symptomatic of a broken stem bridge. Aftermarket CNC-machined brass replacements circulate among watchmakers, and aftermarket "cal. Prince TS" winding stems are commercially available. Owners of Cal. 300 Princes should treat the stem bridge as a known maintenance item rather than a hidden fault.

	The Aegler-Gruen marketing split is a related authentication concern. Aegler supplied shaped movements to Gruen as well as Rolex; Rolex took the British Empire markets, Gruen took the United States market. The Gruen Cal. 877 used in the Gruen Techni-Quadron is the architectural sibling of the Rolex Cal. 300 — the same Aegler movement under a different brand. Some Prince literature lists "Cal. 877" as a Prince caliber; this is a misattribution traceable to the Gruen-Rolex sibling relationship and should be excluded from canonical Prince caliber listings ~~(per Oren Hartov, Analog/Shift)~~. A Gruen-stamped movement under a Rolex Prince case is a known transplant pattern.		The Aegler-Gruen marketing split is a related authentication concern.
