	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.

Research-grounded case-detail update: crystal is Tropic 17 domed acrylic (T17 cohort 5510/6200/6538/7924; T19 is service-replacement); caseback is screw-down threaded Oyster per Bonhams 15422/115 + 16805/140 primary attestations

	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 acrylic.

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 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 automatic, full-rotor — not a bumper movement. 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 ~~(Wind Vintage; Watchprosite reference thread; Harrington's)~~. The 1530 is therefore a watershed movement on the Submariner — first appearance, but pre-chronometer. The chronometer upgrade to 1560 follows on the 5512.

	A small forum thread (RolexForums) introduces a contradiction: some military-issue 5510 examples may have carried caliber 1520 instead of 1530. The published reference literature does not corroborate this, and no auction lot in the surveyed corpus documents a non-1530 5510. Treat it as a forum-level claim awaiting source confirmation; the 5510 is canonically a 1530 reference.

	The 5510 carries an Explorer-dial branch tied to the Royal Australian Navy. Approximately four RAN-issued 5510 MilSubs are known per Sotheby's 2023 catalog; the dial layout reads 3-6-9 with the standard Submariner depth-rating beneath, and the lugs are fixed-bar (issued for nylon strap mount). Sotheby's Important Watches 2023 lot 107 documents the configuration with USD 160,000–320,000 estimate; Phillips~~'s Submariner~~ Explorer-dial editorial ~~article~~ identifies the 362,xxx serial cluster for the RAN branch. The Phillips article and Fratello's RAN MilSub feature are the canonical editorial sources.		The 5510 carries an Explorer-dial branch tied to the Royal Australian Navy.

	Antiquorum Monaco 2018 lot 314-248 documents a reprinted Explorer dial on case 362,187 — the reprint downgraded the lot to a EUR 33,488 hammer against a 20,000–25,000 estimate. Original Explorer-dial 5510s sit at the apex of the reference's collector market.

Q1 1958 to late 1959 production with 362,xxx serial cluster. ~300 examples (Phillips/Sotheby/Bonhams) vs 500 (Fratello) vs 1000 (dealer copy) — capture as contradiction. Cal 1530 NOT chronometer-rated (chrono came with 1560 on 5512). 8mm Brevet identical to 6538, distinct from 7mm 5512. Bond on-screen = 6538, not 5510 (Horologium explicit). Add RAN MilSub Explorer dial branch (~4 known). 11-lot auction record. 7206/58 period-correct, 93...
