The Omega GF 620 factory spare-parts catalogue series

Every answer comes out of the black books.

Omega's own factory spare-parts catalogues — the GF 620 series — and the American Watchmakers Institute microfiche set, about 1,200 frames of parts identification and technical bulletins. Volumes 620-1, 620-3 and 620-5 are on the shelf here and the 620-4 sections are held; 620-6 and the microfiche set arrive in October. Photographed and typed by hand into a database. Every line of a report is cited to the volume it came from. Not copied from somebody else's website.

  2. The case, matchedWas this case built for this movement — or is it a watch built out of parts? That's the question the Extract from the Archives never answered.
  3. The age, datedSerial against the published tables, disagreements shown, not hidden.
  4. Three honest valuesAs a watch, as parts, as gold — including the bare-case weight nobody else publishes.

Model guides

What it is, which calibres, which references, what it's worth. One page per model.

Who's doing this.

Started with one Omega I couldn't identify and got tired of guessing. Built a database so I'd never guess again.

Now it's a breaker's yard — movements in, parts out, and every one of them named right.

The love for Omega watches took me down this road, and now there's a place to identify what you really have, and a treasure of Omega part interchangeability waiting at Watch Breaker.

Six photos. The weight. A day's patience.

Selling and want the asking price to hold up? Buying and want to know before the money moves? The watch stays where it is.
