	The 5510 case measures approximately 38mm without crown — slightly larger than the 37mm small-crown 5508 it ran alongside. Bonhams 15422/115 catalog reads "8mm Brevette crown (larger than the standard 6mm), which was launched in 1958." Phillips Geneva XX 2024 lot 220 describes the "thicker case and an 8mm crown" as defining features. The 8mm "Brevet" signed crown is identical to the 6538 and distinctly larger than the 7mm crown introduced on the 5512 (Monochrome 55XX/1680 history). The 5510 carries no crown guards — its single sharpest visual differentiator from every Submariner that follows.

	The bezel is the friction-rotating dive type with a gilt-printed insert: minute graduations 0–60 with a luminous triangle at 12. The crystal is the domed acrylic Tropic 17 (29.50mm), the same crystal family the 5510 shares with the 6200, 6538, and the Tudor 7924; the Tropic 19 used on the 5512 / 5513 / 5514 / 5517 appears on 5510s only as a later service replacement. The case profile reads slightly thicker than the 5508 to accommodate the larger crown tube and the deeper 200m rating.

	The 5510 is the first Submariner fitted with caliber 1530, replacing the 1030 that ran the 6538 and earlier 6536/1 examples. ~~The~~ 1530 carries 25 jewels, a straight-line lever escapement, a self-compensating Breguet balance spring, an index regulator, and a monometallic balance with shock absorber (Antiquorum 204-163; Harrington's). It is a full-rotor automatic caliber. Power reserve runs approximately 42 hours.		The 5510 is the first Submariner fitted with caliber 1530, replacing the 1030 that ran the 6538 and earlier 6536/1 examples. On the two lots documenting this specific reference the 1530 carries 25 jewels, a straight-line lever escapement, a self-compensating Breguet balance spring, an index regulator, and a monometallic balance with shock absorber (Antiquorum 204-163; Harrington's). Sibling references running the same caliber across its 1957–1965 life show a wider range — [[Reference:5508\|5508]]'s own documented examples run 17, 25, and 26 jewels depending on market and production date — so 25 jewels describes the 5510's cited examples specifically, not a fixed spec for the caliber as a whole. It is a full-rotor automatic caliber. Power reserve runs approximately 42 hours.

	The 5510's caliber 1530 is not chronometer-rated. The "Superlative Chronometer Officially Certified" four-line dial text and the chronometer-grade caliber 1560 came in with the 5512 transition in 1959. The 1530 is therefore a watershed movement on the Submariner — first appearance, but pre-chronometer. The chronometer upgrade to 1560 follows on the 5512.

It is ~~automatic,~~ full-rotor ~~— not a bumper movement~~. Power reserve runs approximately 42 hours.

A small forum thread (RolexForums) raises the possibility that some military-issue 5510 examples carried caliber 1520 instead of 1530.

	Every documented 5510 dial carries 200m=660ft depth printing in the two-line layout below the Submariner wording. The depth-rating step from the 100m ~~of the contemporary 5508 small-crown~~ to the 200m of the ~~5510 is itself a signature distinction —~~ the 5510 is depth~~-rated up from~~ the ~~5508, not transitional within~~ its own run.

The depth-rating step from the 5508's 100m to the 5510's 200m separates the two references; the 5510 held one depth rating for the whole of its own production run. No 100m or four-line variant surfaces in documented examples.

	The bezel is the friction-rotating dive type with a gilt-printed insert: minute graduations 0–60 with a luminous triangle at 12. The crystal is the domed acrylic Tropic 17 (29.50mm), the same crystal family the 5510 shares with the 6200, 6538, and the Tudor 7924; the Tropic 19 used on the 5512 / 5513 / 5514 / 5517 is a service-replacement ~~option on the 5510, not its original spec~~. The case profile reads slightly thicker than the 5508 to accommodate the larger crown tube and the deeper 200m rating.

	The caseback is screw-down threaded Oyster construction, identical to the 6538 architecture. The exterior wears smooth without a date stamp; the interior carries the reference, the case number, and a Roman-quarter date stamp in the format "Q.YY" (Bonhams 15422/115 cites "inner case dated 1.1958" on an early-1958 example; Bonhams 16805/140 cites "screw on back stamped inside 1.1958" on the Royal Navy lot, case 362,252).

	The 9315 / 93150 folded-link Oyster turns up frequently on cataloged 5510 examples but the clasp dating proves these are bracelet swaps. Bonhams 16805/140 (RN diver provenance, case 362,252) wears "stainless steel Rolex 93150 with 580 end pieces" — the bracelet dates later than the head and is a documented service replacement. Antiquorum Monaco 2019 lot 322-315 documents a riveted Oyster with deployant clasp stamped 1.67 (Q1 1967), again period-late or service replacement. Phillips Geneva XX 2024 lot 220 documents a "Big Logo" stretch riveted bracelet with clasp dated 2.59 — close to the case-head date and consistent with original-delivery.

	The diver's extension feature is absent on the period 7206 fitment; the extension appears with the later 9315 / 93150 swap. A 5510 ~~sold~~ with a clean original 7206 / 58 / 1958–59 clasp is ~~the rarity, not the norm~~.

	The 5510 ~~trades~~ at the top of the early Submariner market on rarity ~~rather than dial drama~~. Unrestored Swiss-only and gilt examples cluster CHF 100,000–200,000; tropical examples and RAN MilSubs sit higher. Reprinted-dial examples and military-issue lots with later bracelets settle at the lower end. The reference's narrow collector audience values the technical handoff from the big-crown era to the chronometer-rated 5512 / 5513 generation that followed.
