IWC Schaffhausen Iw459801 Portofino Automatic Day Night

Owners widely praise the IWC Schaffhausen Portofino for its classy, understated aesthetic and elegant design, with some finding it a "lifetime watch" and a spark of joy. The clean dial and classic dress watch appeal are frequently highlighted, and one owner noted the movement as reliable and accurate. However, opinions on size vary across the line, with some finding larger variants too big and wishing for smaller options, while others with smaller wrists found a 40mm size perfect. One owner of a different Portofino variant reported it losing nearly 10 seconds a day. Overall, owners and reviewers appreciate the IWC Schaffhausen Portofino for its elegant dress watch appeal and refined aesthetic.

Sternglas Kanton

The Sternglas Kanton is praised for its refined Bauhaus-inspired design, featuring a silver-plated dial and luminous hands and dots for excellent legibility. Owners and reviewers highlight its comfortable 39mm case size, measuring 10mm thick, and the visible STP 1-11 automatic movement through a sapphire crystal case back. Accuracy figures vary, with one source noting +15 seconds per day, while another suggests improved accuracy over previous models. Overall, owners and reviewers rate the Sternglas Kanton highly for its blend of Bauhaus design and Swiss precision at an affordable price point.
