On balance, owners and reviewers appreciate the IWC Schaffhausen Iw658601 Portofino Automatic for its classic dress watch aesthetic and wearability, though some debate its value.

Omega Constellation Co Axial Master Chronometer

Owners widely praise the Omega Constellation Co Axial Master Chronometer as an underrated model and a potential heirloom, citing its handsome, well-built nature and refined yet sporty design. One owner notes that Omega does not offer alternative straps, and aftermarket options may not fit due to the Constellation's notched design.

Overall, owners and reviewers consider the Omega Constellation Co Axial Master Chronometer a well-built, elegant timepiece that is highly regarded as a potential heirloom.
