Reviews

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

Knot Watches AT1-40SSV

Owners widely praise the Knot Watches AT1-40SSV for its solid build quality, clean aesthetic, and good finish, with the small seconds hand accurately hitting its markers. The 40mm case size is generally considered good, though one owner felt it wore "a tad on the small side." Opinions on the included straps are divided, with some appreciating their unique Japanese fabrics and leathers and finding them soft and ready-to-wear, while others express disappointment with their quality and note they can be stiff initially. One owner also flagged the small crown as a nitpick due to its low placement. Overall, owners rate the Knot Watches AT1-40SSV highly for its overall quality and finish at the price point.

Patek Philippe Aquanaut 5164

The Patek Philippe Aquanaut 5164 is widely praised as a comfortable and useful travel tool, with its dual-time zone function described as simple yet brilliant. Owners highlight the watch's exceptional finishing, including sharp brushing and polished bevels, and appreciate the pliant composite strap. The grey-brown dial with a geosphere pattern and white gold indices filled with Super-Luminova are noted as positive features. Some owners find the detailing and finishing to be up to Patek standards, with steel polishing quality exceeding expectations. The watch is considered a great all-rounder, comfortable enough for daily wear, feeling like an extension of the arm. However, the case tends to attract scratches when new, and some owners consider integrated-bracelet-style watches like the Aquanaut a poor choice for rough handling due to the case being integral to the overall appearance. The retail price of the 5164A is noted as significantly higher than some competitors.

From video reviewers

The dual-time zone complication is a practical and valued feature. The $20,000 premium over the 5167 solely for this complication is a significant point of contention.
