Reviews

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Atelier Wen Porcelain Odyssey — Ji

Atelier Wen Porcelain Odyssey — Ji owners praise its beautiful, legible porcelain dial and well-executed blued hands, noting refined cultural elements and excellent attention to detail. One owner reports the crown operation is rougher than expected, stiffening during manual winding, though automatic winding functions well. The 39mm case design is noted as strongly resembling another brand's model. On balance, owners and reviewers highly regard the Atelier Wen Porcelain Odyssey — Ji for its striking dial and value proposition.

From video reviewers

The porcelain dial and overall finishing are praised. The value proposition is debated, with one reviewer citing $5,850 and another suggesting under $1000.

IWC Schaffhausen Portofino Perpetual Calendar

Owners widely praise the IWC Schaffhausen Iw344602 Portofino Perpetual Calendar for its elegant 40mm size and clean dial, with one owner calling it a beautiful and smart watch. Reviewers note its Kurt Klaus perpetual calendar module, accurate to one day over 577.5 years and requiring no adjustment until 2100, housed within the IWC Caliber 82xxx automatic movement. Some owners find the dial busy and the year display off-center, while others consider the design slightly feminine. One owner reported potential issues with setting the calendar backward and a perceived thickness, though the manufacturer lists the case at 40mm. On balance, owners and reviewers appreciate the IWC Schaffhausen Iw344602 Portofino Perpetual Calendar for its compact size and sophisticated perpetual calendar complication.
