	This Aegler-supplied 10½-ligne hand-wound family uses the 700/710 architecture. It has a straight-line lever escapement, monometallic Superbalance adjusted to six positions, self-compensating Breguet balance spring, and swan-neck micrometer regulator, with no documented shock protection. The movement powers the original Air-King 4925 and its Air-Lion, Air-Tiger, and Air-Giant siblings, including the sub-seconds 4365, mid-size 4444, and 4647 Hunter Precision. Its architecture links the pre-war Prince and Bubbleback movements with the post-war automatic Cal. 1030. Rolex's factory caliber table dates Cal. 700 and 710 to 1938. It lists Cal. 720 separately as an automatic movement with shock protection, not as a third member of this manual pair.

			Auction catalogues describe compatible 10- to 10½-ligne manual movements in [[Reference:2765\|2765]] and [[Reference:3009\|3009]], but none of the surfaced records shows a Cal. 700 stamp. Both reference pages therefore treat the assignment as plausible rather than confirmed. The four documented [[Reference:1873\|1873]] watches are also manual, but their catalogues name no caliber.

Clarify Cal. 635 evidence from ref. 3599 auction records

	Rolex's factory table gives the lineage as Cal. 600 to 635 to 645. It places Cal. 635, 640, and 645 under the A.260 size code at 26.4mm and 18 jewels, all entered in 1950 and all shock-protected. The shock system separates this 1950 A.260 group from the 1936 Cal. 620 base.		Rolex's factory table gives the lineage as Cal. 600 to 635 to 645. It places Cal. 635, 640, and 645 under the A.260 size code at 26.4mm and 18 jewels, all entered in 1950 and all shock-protected. The shock system separates this 1950 A.260 group from the 1936 Cal. 620 base.

			Antiquorum catalogued a subsidiary-seconds [[Reference:3599\|ref. 3599]] as Cal. 635 with 19 jewels and described the caliber as 9¾ ligne, made from 1940 to 1951. Those details conflict with the factory-table size, jewel count, and 1950 entry above. Christie's also catalogued a visibly centre-seconds 3599 as Cal. 635, which conflicts with the caliber's small-seconds architecture. Without movement photographs, the Christie's caliber entry is best treated as a catalogue error rather than evidence for a centre-seconds Cal. 635.

	Jewel counts also vary according to whether a catalogue includes the automatic module. Bonhams describes the related [[#cal-745\|Cal. 745]] as "18 jewels plus 7 rotor jewels." Its 20-jewel description of a Cal. 645 in a 6085, against the factory table's 18, does not necessarily indicate a different movement.

	Auction houses usually catalogue refs. 5700 and 5701 under the base caliber. Antiquorum assigns a 1963 ref. 5700 to Cal. 1530 and a 1972 example to 1520, though neither base movement has a date. Read as family shorthand, those entries match Rolex's parts catalogues, which file 1535 components with the 1530 and 1525 components with the 1520. They support the lineage but do not confirm the exact caliber number.		Auction houses usually catalogue refs. 5700 and 5701 under the base caliber.

	The table's mechanical figures derive from the 1530 base because no auction lot identifies a 1535 directly. ~~Hairspring evidence~~ conflicts: auction wording gives a flat spring, while Rolex balance assembly 7855 for the 1530 uses a Breguet overcoil. Repeated catalogue boilerplate is more likely than a separate variant. The 1535 predates Microstella and uses an index with a screwed balance, consistent with the 5700's Precision grade.

	Cal. 3135 used KIF shock protection throughout its run and never received Paraflex. Rolex assigned new caliber numbers to Paraflex versions: 3130 became 3132, 3155 became 3156, and 3186 became 3187. The larger Paraflex date movement for the Datejust II was Cal. 3136. A 16610 or 116610 described as having Paraflex is therefore misidentified.

	Parachrom arrived during the Cal. 3135 run, but the transition date is unsettled. The niobium-zirconium alloy receives a uniform anodised oxide layer about 50 nanometres thick, which gives the hairspring its blue colour and stabilizes its restoring torque. Published dates for its adoption in Cal. 3135 range from about 2005 to 2009, with transitional examples reported on both sides. The ceramic-bezel 116610 uses it consistently from 2010. ~~Hairspring~~ colour is therefore only a rough dating marker.

	Two wear points sit in the automatic works. The anodised purple-red reversing wheels, part 3135-540, are visible through the rotor cutout and identify the movement without disassembly. Failure produces free rotor spin without winding or gritty manual winding. Epilame belongs across the reverser assembly, while oil is confined to the arbor and bearing points; oil on the teeth or clicks can jam the mechanism. The oscillating-weight axle, part 3135-568, runs in a plain jewelled sleeve. Wear causes a rattle, rotor contact with the caseback, and red dust in the movement. Rolex supplied mainsprings in standard part 3135-311 and weaker 3135-311-1 versions, a relevant distinction when assessing a rebuilt movement.		Two wear points sit in the automatic works.

	The jump-hour member of the T.S. family, alongside Cal. 300 (small seconds) and Cal. 310 (centre seconds) above. Christie's Geneva (14 May 2018, lot 113) and Sotheby's Geneva (November 2016, lot 135) both catalogue it in the [[Reference:1491\|1491 Brancard Jumping Hour]]: an 18-jewel, chronometer-rated movement on the T.S. base, in the 1491's rectangular case. Watch Wiki notes the jump-hour disc mechanism works on much the same principle the Datejust's date disc would decades later — an early instance of a mechanism Rolex returned to on a completely different watch. Surviving examples carry Glasgow import hallmarks from 1930-31, consistent with the shared T.S. base's own 1928-35 production window.

Christie's Geneva (14 May 2018, lot 113) and Sotheby's Geneva (November 2016, lot 135) both catalogue it in the [[Reference:1491\|1491 Brancard Jumping Hour]] as an 18-jewel, chronometer-rated movement on the T.S. base, in the 1491's rectangular case. A separate 1491 example, movement plate marked "15 Rubies" and Extra Prima rather than Ultra Prima, is catalogued the same way by Christie's (lot 5130736); the jewel count tracks the grade tier rather than a single fixed spec. Watch Wiki notes the jump-hour disc mechanism works on much the same principle the Datejust's date disc would decades later — an early instance of a mechanism Rolex returned to on a completely different watch. Surviving examples carry Glasgow import hallmarks from 1930-31, consistent with the shared T.S. base's own 1928-35 production window.

	Two further notes apply across the whole family rather than to one caliber. The 1491 case runs deeper than the 1490's to house the jump-hour module — that case-depth difference is the canonical way to catch a 1490 retrofitted with a later module and passed off as a genuine 1491. Three module-specific service patterns turn up in the collector record: a weak jump-impulse spring producing a "lazy" disc advance, a worn disc-retention pawl producing hour-disc jitter, and a misaligned dial aperture that reveals fragments of two numerals at once.
