Reviews

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

Blancpain Fifty Fathoms Automatique

Owners widely praise the Blancpain Fifty Fathoms Automatique for its timeless design, high-quality finishing, and excellent legibility, with its virtually scratch-proof sapphire crystal bezel noted as among the nicest available. The 38.2mm case is considered wearable daily, feeling stealthy yet substantial, though one owner found this size potentially too small. Some reviewers dislike the engraved brand name on the case side, and one noted an odd 21.5mm lug width. On balance, owners and reviewers rate the Blancpain Fifty Fathoms Automatique highly for its exceptional finishing and comfortable wearability.

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.
