What people say

Owners + reviewers, side by side

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

Citizen Promaster Diver Automatic

Owners widely praise the Citizen Promaster Diver Automatic for its lightweight titanium build, comfortable wear, and good specifications at its price point, with one owner highlighting its accuracy and dynamic dial made from recycled materials. Some users find the bezel action spongy and the bracelet subpar, while others note the overall finish is basic due to the brushed titanium. A reviewer also points out a preference for sapphire crystal and ceramic bezel inserts. On balance, owners rate the Citizen Promaster Diver Automatic highly for its value proposition as an affordable, lightweight, and accurate dive watch.

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

The Prospex Sea Seiko Diver’s Watch 60th Anniversary Limited Edition features a 40mm case, 300m water resistance, and a 72-hour power reserve from the Calibre 6R55 movement, with a new grey bezel insert and a wave-patterned silvery-white dial. Owners find the watch attractive and the large case wears well without feeling bulky. However, some consider the price of €1900 for a 6R54 movement with an accuracy of +25/-15 seconds per day to be too high, and the production run of 6000 units is not seen as a true limited edition. Overall, owners find the Prospex Sea Seiko Diver’s Watch 60th Anniversary Limited Edition aesthetically pleasing with good wearability, but express concerns regarding its value proposition and movement accuracy for the price.
