Owners and reviewers widely praise the Jaeger-LeCoultre Duometre Chronograph Moon's movement finishing, with one owner calling it a "gorgeous piece" and another comparing it favorably to A. Lange.

A drawback cited by reviewers is the shift from nickel silver (German silver) to rhodium-plated brass in the new calibre 391 movement. Overall, owners and reviewers highly regard the Jaeger-LeCoultre Duometre Chronograph Moon for its exceptional movement finishing and intricate chronograph complications.

Owners widely praise the Omega Speedmaster Moonwatch Professional Co Axial Master Chronometer Chronograph 42mm for its historical significance, iconic design, and wearability, with some finding it provides more personal satisfaction than more expensive watches.
