What people say

Owners + reviewers, side by side

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

IWC Schaffhausen Iw501705 Portugieser Automatic

Owners widely praise the IWC Schaffhausen Iw501705 Portugieser Automatic for its timeless beauty, stunning design, and pure class, with particular admiration for the dial's depth and brilliance achieved through 15 layers of lacquer. The 7-day power reserve, housed within a 42.4mm case, is a significant draw, often noted as a compelling feature for a watch of this size. Some owners find the 42.4mm case to be on the larger side, with one owner preferring it on a strap over a bracelet and another noting it was pushing the size limit for a 6.25" wrist. A desire for smaller case size options, specifically 38mm or 36-38mm, is also expressed by multiple owners. On balance, owners and reviewers rate the IWC Schaffhausen Iw501705 Portugieser Automatic highly for its captivating aesthetics and impressive 7-day power reserve.

Omega Seamaster Aqua Terra 150M Co Axial Master Chronometer

Owners widely praise the Omega Seamaster Aqua Terra 150M Co Axial Master Chronometer for its versatility as a daily wear watch, with many highlighting its stunning finishing and the beauty of its dials, which can appear more gray than blue in person or pop vibrantly in sunlight. Reviewers and owners alike commend its understated design, making it suitable for both dress and sport occasions, and some consider it a great value. A few owners find the 41mm case size borders on large due to its plain dial, with some preferring smaller variants for better proportions on smaller wrists. One reviewer regrets the solid case back obscuring the Omega 8900 movement. Overall, owners and reviewers rate the Omega Seamaster Aqua Terra 150M Co Axial Master Chronometer highly for its versatile design and impressive finishing.
