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 Fujitsubo

Owners widely praise the Citizen Promaster Fujitsubo for its compact size, light weight, and muted blue dial, with many appreciating the block hour hands for legibility and its classic, tough design. The watch is noted for its 1970s heritage, titanium case and bracelet, sapphire crystal, and smoother, higher frequency automatic movement. However, some owners find the Mercedes hands distracting, the bracelet chunky with male end links, and the winding action uninspiring, with one describing the bezel as plastic-like and the overall feel as cheap. The Citizen Promaster Fujitsubo is considered by some to offer incredible value and a worry-free beater watch, though others feel it is overpriced at full retail. Overall, owners rate the Citizen Promaster Fujitsubo highly for its comfortable wearability and classic aesthetic at its price point.

Seiko Prospex Sea Seiko Prospex 1965 Heritage Diver’s Watch Save the Ocean Limited Edition

The Prospex Sea Seiko Prospex 1965 Heritage Diver’s Watch Save the Ocean Limited Edition is praised for its compact 40mm case and the new Caliber 6R55 movement offering a 72-hour power reserve. Owners and reviewers highlight the stunning dials as a strong suit for Seiko. However, the 6R movement's accuracy is a point of disappointment for some, who wish for improvements closer to other movements, though others accept it given the excellent overall package. Press images suggest the bracelet end links may appear disjointed. Overall, owners and reviewers rate the Prospex Sea Seiko Prospex 1965 Heritage Diver’s Watch Save the Ocean Limited Edition well, with the stunning dials and improved power reserve being the biggest reasons.
