Key Points from the Discussion

These detailed service posts serve as a public service announcement, educating those who underestimate the complexity, organization, precision, and specialized tools required for mechanical watch servicing.
The Omega Dynamic Chronograph, with its caliber 1138 (similar to the Speedmaster Reduced), is often considered challenging due to its stacked chronograph module, but experienced watchmakers find it manageable.
The photo essay provided valuable insights into the internal workings of a chronograph module and the process of removing a crown stem, which is useful knowledge for enthusiasts.
While disassembly is interesting, the real challenge lies in reassembling the intricate components of the watch.
