Reviews

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

Cronos Sub Diver 44mm No Date (L6009)

Owners widely praise the Cronos Sub Diver 44mm No Date (L6009) for its exceptional value, with one owner noting its 2000m water resistance and BGW9 Superluminova lume as standout features. The watch is described as a "beast" due to its 44mm case and 17mm thickness, though some find it wears surprisingly well for its size and is versatile for everyday and business casual wear. Some owners report the substantial weight and lug-to-lug distance make it feel heavy on the wrist, with one individual replacing the bracelet to reduce its overall weight. Overall, owners rate the Cronos Sub Diver 44mm No Date (L6009) highly for its impressive water resistance and value, despite its considerable heft.

Seiko Prospex Sea Seiko Diver’s Watch 60th Anniversary Limited Edition

Owners find the Seiko Prospex Sea Seiko Diver’s Watch 60th Anniversary Limited Edition very pretty with an excellent, non-bulky 42mm case. Reviewers note its upgraded clasp with a new diving suit extension system and a wave-patterned silvery-white dial. However, the price of €1900 for a Seiko 6R54 movement with accuracy of +25/-15 seconds per day is considered too expensive by some, and the 6000-unit production run is not seen as truly limited. On balance, owners and reviewers find the Seiko Prospex Sea Seiko Diver’s Watch 60th Anniversary Limited Edition aesthetically pleasing with a comfortable case, though its value proposition is debated due to the movement's performance and price.
