	Caliber 1030 is confirmed across the 6536/1 corpus. Specifications: 25 jewels, 18,800 vph, ~42-hour reserve, 28.5 × 5.85mm, monometallic balance, blue Breguet overcoil. The 1030 is Rolex's first bidirectional automatic, introduced in 1950 — the architecture that ~~replaced~~ the ~~bumper movements~~ of the ~~earliest~~ Submariners. The butterfly rotor is stamped ROLEX PERPETUAL PATENTED.		Caliber 1030 is confirmed across the 6536/1 corpus. Specifications: 25 jewels, 18,800 vph, ~42-hour reserve, 28.5 × 5.85mm, monometallic balance, blue Breguet overcoil. The 1030 is Rolex's first bidirectional automatic, introduced in 1950 — the butterfly-rotor architecture that succeeds the thicker uni-directional A-series Perpetuals (A260 / A290 / A295 / A296) of the early Submariners. The A-series itself is full-rotor, not bumper; Rolex never produced a bumper caliber. The butterfly rotor is stamped ROLEX PERPETUAL PATENTED.

	Chronometer-certified (OCC) and non-certified versions both exist within the 6536/1 family on the same base caliber. The split is a certification distinction, not a mechanical one — some movements were sent for chronometer rating and some were not. The Sotheby's December 2018 lot 252 caseback is stamped 6536/1 with III.57 (third quarter 1957) on a chronometer-rated four-line dial example; non-chronometer 6536/1 examples surface across the same period with the standard two-line dial.

	The 6536/1 ran 1955 to 1959 across ~~the auction~~-house ~~corpus~~. Hard caseback evidence anchors the late-1955 introduction: a Q4-1955 caseback ("4 55") on case 112,256 and an IV.55 caseback on case 112,341 are both 6536/1 stamps. Mid-run examples carry caseback codes I.57, II.56, II.57, and III.57 across cases 155,502 / 229,640 / 306,989 / 30x,xxx; late-run examples extend into 1959 with cases in the 39x,xxx range.

	The parent 6536 and the 6536/1 ran concurrently rather than sequentially within the 1955-1959 window. Caseback engraving, not the calendar date, decides which variant a given example belongs to. The 2024 Rolex archive analysis gives the parent 6536 a total of 5,350 pieces 1955-1959 — 44% of the 12,144 total no-crown-guard Submariners across the five references (6200, 6204, 6205, 6536, 6538). No separate 6536/1 vs parent 6536 production split is published.		The parent 6536 and the 6536/1 ran concurrently rather than sequentially within the 1955-1959 window.

	The bezel evolution within 1957 alone is the cleanest single dating tool on a 6536/1. The earliest 1957 examples carry a silver triangle at twelve with no minute hash marks across the first fifteen minutes — the cleanest and earliest layout. Mid-1957 production keeps the no-hash format but switches to a red triangle at twelve. Late 1959 production carries the red triangle alongside individual minute hash marks across the first fifteen minutes — the closest ancestor to the bezel that defines the 5512.

	The crown is the original single-coronet "Brevet" 6mm with double-lock. A three-dot crown on a 6536/1 is a service replacement.

	Rolex used numeric suffixes (/1, /2, etc.) to flag a caseback engraving update inside an existing reference — a tracked variant rather than a new reference number. The 6536 and the 6536/1 share the case, the production period, the caliber, the dial-text variants, the bezel inserts, the bracelet options, and the case dimensions. The caseback is the only ~~definitive~~ distinction.

The caseback is the only standard distinction.

	A caseback engraved "6536/1" in full belongs to the sub-variant; a caseback reading "6536" alone belongs to the parent. Both stampings exist on cases produced in the same period — the parent 6536 stamp continues to appear well into the 6536/1 era. The 6536/8 transitional variant (with crossed-out "6538" engraving and "6536" re-engraved over the strikethrough) is documented separately on the parent reference page; it is its own subvariant rather than a 6536/1 ancestor.
