Owners widely praise the IWC Schaffhausen Iw3583xx Portugieser Automatic for its timeless design and comfortable 40.4mm case size, with reviewers noting its clean dial and the nicely finished Calibre 82200 movement. Some owners report accuracy around -7 seconds per day, while others have experienced winding issues with the Pellaton system, though this was resolved by understanding the winding direction. Reviewers mention the lugs appear long, and some owners find the 30-meter water resistance a drawback for a modern watch. Overall, owners and reviewers rate the IWC Schaffhausen Iw3583xx Portugieser Automatic highly for its classic design and wearable case size.

The Sartory Billard SB04-E is widely praised for its impressive and deep dials, with one owner highlighting the unreal, moving appearance of the blue guilloché. Reviewers note its sensible 39.5mm wearability and composition that looks more expensive than its price, with customization options also called out as a key strength. The La Joux-Perret G101 automatic movement powers the watch, offering a 68-hour power reserve. Some owners point out that the caseback has slightly sharp edges and the crystal could be more domed. On balance, owners and reviewers rate the Sartory Billard SB04-E highly for its visually striking dials and overall value proposition.
