Rolex changed what a wristwatch could be. The Oyster case made watches waterproof. The Perpetual rotor made them self-winding. The Submariner made them dive-rated. The Daytona timed races. The GMT-Master crossed time zones for Pan Am pilots. These are not just expensive objects — they are engineering milestones that shaped an entire industry, and every one of them has a production history worth documenting properly. That is what this project is for.

We kept running into the same problem: the good information is scattered across forum threads that get buried, auction archives behind paywalls, out-of-print books trading for more than the watches they describe, and dealer sites that disappear when the business closes. So we started consolidating it. Every claim here traces to a named source. Where sources contradict each other — and they do, constantly — both sides are shown. Where nobody actually knows the answer, we say so instead of guessing. How this is built →

Reference library

Submariner

We started here because the Submariner is the reference that never lets you stop researching. Thirty-nine distinct references across seventy years of production. The 6204 showed up in 1953 with a 100m depth rating and no crown guards, and by the time you get to the current 126-series the watch has been through gilt dials, matte dials, aluminum bezels, ceramic bezels, acrylic crystals, sapphire crystals, and more bracelet configurations than most people realize exist. A single reference like the 5513 ran for 27 years and produced enough dial variants to fill its own taxonomy. We have 36 articles live — each one covers specs, movement history, dial variants, bracelets, and whatever the auction record actually says. More references are in progress.

Highlights:

• 6538 — the James Bond Submariner
• 5513 — 27-year production run, the broadest vintage reference
• 1680 — first Submariner Date, Red Sub and White Sub eras
• 16610 — the 23-year benchmark modern Submariner
• 116610LV — the "Hulk," now a modern collectible
• 114060 — the last 40mm no-date, "the last small Sub"

Bubbleback

Before the Submariner there was the Bubbleback. The Bubbleback is the Oyster Perpetual's first act — the watches Rolex built between 1933 and the mid-1950s with a domed caseback, because the 360-degree automatic rotor the company had just patented was too thick to fit a flat case. Twenty-two years of production, roughly 172 variants per the Vintage Rolex Field Manual, and inside the first one is caliber 520 with step-by-step service instructions engraved around the main plate — Rolex literally teaching watchmakers how to service a movement the industry had never seen. The Bubbleback is where Rolex stopped being a precision watchmaker and started being the brand that the rest of the industry would spend the next half-century catching up to. Five reference articles are live, covering the lineage from the first manual-wind gold Oyster through the first Datejust.

Highlights:

• 2136 — early manual-wind gold Oyster, cushion and octagonal cases (1926–1940)
• 1858 — the first Bubbleback, Cal. 520, Didactic engraved movement (1933)
• 3131 — the first two-piece case Bubbleback, Cal. 620 (1936)
• 3372 — the "Luxury Model," engine-turned bezel flagship (1938–1950)
• 4467 — the first Datejust, Ovettone, Jubilee bracelet debut (1945)
