The purpose of this page is to create a new space dedicated to any new information and/or correction we could be aware of regarding our Moonwatch Only book, and more generally the Speedmaster Moonwatch models.

These new information could be the result of mistakes or inaccuracies written in the book (we will start our analysis from the 3rd edition), or to new research that could have been conducted directly by us, or in collaboration with the OMEGA Museum team, or with some other collector.

We want this page to be dynamic, and we will update it and communicate about it every time it will be necessary.

We hope you’ll enjoy it.

# 1  – Dial types on reference ST 145.022-74

We have indicated in the book that the only dial type that had been fitted on the reference ST 145.022-74 was the C2. Medium S – Flat Dial.

However we have observed some rare 145.022-74s fitted with the precedent type (C1. Medium S – Step Dial), which seems to be possible for the very early production.
