Documented exclusively on the [[Reference:3361|3361 Aerodynamic]] / 3362 / [[Reference:3937|3937]] wedge-shaped Prince family — every documented 3361 catalog entry names Cal. 310 specifically (Antiquorum Mondani 2006 lot 209/210, NY 2015 sale 296 lot 73 mvt T94122, PatekMonger Cuervo y Sobrinos). Available in BOTH sub-seconds and **centre-seconds** variants; the 3361/3362/3937 receive the centre-seconds variant. Cal. 310 production ended 1938 but Aegler stockpiled movements that Rolex cased into 3361 production through 1952 — the case-and-movement number divergence reflects this stockpile pattern (e.g. Mondani 1952 case 899,677 carries a movement number significantly lower than the case). Auction-house catalogs commonly under-specify Cal. 310 as 'Cal. 300 family' — treat that label as under-specified, not as a sub-caliber distinction | ||
