Text audit: voice, clarity — cut four negation-pivot constructions in narrative prose (no fact changes) |
Fix T.S. 300 ligne error (7¾→7½) and rework caliber-number claims per Reference:Movements factory-table cross-check: 527/579/841/1004/1759 are almost certainly plate serials not calibers, and Cal. 414/701 have no documented Prince connection |

Aegler shaped chronometer movement, Cal. 300 / T.S. 300 family (7½ ligne), with several catalogue-printed movement numbers (527, 579, 841, 1004, 1759) that are most likely plate serials rather than distinct calibers, in Prima, Extra Prima, and Ultra Prima grades. Documented in stainless steel, 9K/18K gold, two-tone, bicolor, and platinum + 9K composite. Production approximately 1928–1942. | ||

The 1862 runs on the same Aegler shaped-movement family as the 971 and 1490. The 1927 Wilsdorf-Aegler patent that placed the winding barrel and balance at opposite ends of the rectangular movement applies. The Aegler-Rolex relationship was a supplier arrangement (Aegler operated independently in Bienne until Rolex purchased the firm from the Borer family in April 2004, per Tim Mosso's Quill & Pad reporting). | The 1862 runs on the same Aegler shaped-movement family as the 971 and 1490.

What sets the 1862's movement record apart is the spread of | What sets the 1862's movement record apart is the spread of numbers stamped on its bridges. Auction catalogues have printed 527 (Christie's online, c.1934), 579 (Bonhams London, c.1935), 841 (Bonhams London, c.1930, resold through Tajan in 2019), 1004 (Christie's London, 2015, Glasgow import 1936, "officially tested in 8 positions"), and a single 1759 (watch-auctions.co.uk, 1937, Ultra Prima Chronometer, 18-jewel, 6-position) as though each were a distinct Rolex caliber. Cross-checked against Rolex's own factory caliber table on [[Reference:Movements]], these are almost certainly movement serial numbers read off the plate rather than genuine commercial designations — Continental houses cataloguing the same movement class instead cite the grade and the "T.S." size code. Cal. 414, which surfaces on a single Italian dealer listing, and Cal. 701, which rests on one uncatalogued photograph elsewhere in the Prince family, have no documented connection to the Rolex Prince at all and should not be read as confirmed 1862 variants. The base architecture behind all of these stampings is the Cal. 300 / T.S. 300 family — 7½′′′, rectangular plates, produced 1928–1935 — and the Antiquorum-catalogued "Cal. 7½′′′ Extra Prima with Elinvar hairspring" (2022) describes that same movement by ligne size and grade rather than by number. | ||
The | The most defensible reading, consistent with the Reference:Movements analysis, is that the rectangular-plate Cal. 300 / T.S. 300 family runs 1928–1937 and that the various three- and four-digit numbers UK catalogues print on later 1862 movements are plate serials rather than a family of commercial calibers succeeding it. The NAWCC discussion (Doug Sinclair, gmorse, Cary Hurt, March 2013) remains the load-bearing source for the rectangular-plate versus tonneau-plate cutoff, regardless of what number happens to be stamped on any individual movement. | ||
Movement grading runs Prima → Extra Prima → Ultra Prima. The "Chronometer" or "Officially Certified Chronometer" designation on the dial corresponds to Extra Prima or Ultra Prima grade. A Prima movement does not earn the dial mark. The Christie's London 2015 example with | Movement grading runs Prima → Extra Prima → Ultra Prima. The "Chronometer" or "Officially Certified Chronometer" designation on the dial corresponds to Extra Prima or Ultra Prima grade. A Prima movement does not earn the dial mark. The Christie's London 2015 example, catalogued with the number 1004 on its movement, carries an "officially tested in 8 positions" rating — eight-position adjustment is unusual (Swiss and Kew chronometer protocols of the period typically tested in 5 or 6 positions), and the 8-position attribution may indicate a specific Aegler-internal regulation tier rather than a Bureaux-Officiels-Suisse-de-Contrôle certification. | ||
