Kobold Soarway Diver SealvsSinn U18

The Kobold Soarway Diver Seal is noted for its attractive design, particularly with upgraded dials, and its lightweight titanium construction, offering good wrist balance and superior overall construction compared to some alternatives. One owner found the ivory dial a bit pale but noted a brown leather strap transformed its appearance. However, owners widely report significant issues with the company's business practices, leading to extremely long service and repair times. One owner experienced a lost strap and damaged bezel after service, while another reported persistent stopping issues, with the second hand appearing to contact the minute hand, even after warranty replacement. Overall, owners rate the Kobold Soarway Diver Seal highly for its attractive design and lightweight titanium build, despite significant concerns regarding the company's service and repair turnaround times.

The Sinn U18 is praised for its unique deep blue/green dial with three-dimensional oxygen bubbles that change with light, and its comfortable, easily adjustable bracelet. Owners find the watch stunning and a piece of history, appreciating the refined hands. The Sinn U18 features a 44mm, 15.5mm thick case made from German submarine steel, offering a 2000-meter dive specification and Sinn's Ar-Dehumidifying technology, powered by a Sellita SW300-1 movement. The case thickness is apparent, and the watch comes as a complete set with box and papers for $3,000-$3,680. On balance, owners and reviewers rate the Sinn U18 highly for its striking dial and robust build.
