What people say

Owners + reviewers, side by side

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

CWC 1987 SBS Quartz Diver Re-Issue Watch

Owners widely report the CWC 1987 SBS Quartz Diver Re-Issue Watch as very hard-wearing, with good seconds hand alignment and perfect bezel alignment with crisp action. The lume is described as pretty good despite fauxtina, and the watch gains approximately 3 seconds per month. Some owners consider the CWC 1987 SBS Quartz Diver Re-Issue Watch overpriced, while others appreciate its bombproof, toolish design and military heritage.

Seiko Prospex Sea Save the Ocean Special Edition

The Seiko Prospex Sea Save the Ocean Special Edition is widely praised for its attractive, unique, and textured dials, often described as having a "Grand Seiko feel" at a more accessible price point, with specific mentions of wave patterns, lagoon hues, and manta ray motifs. Owners appreciate the smooth bezel operation and satisfactory lume. Accuracy figures vary, with one owner reporting +5 seconds per day, while another notes a range from +1/+2 to about -6 seconds per day. The 6R35 movement offers a 70-hour power reserve, and some models feature sapphire crystals. Criticisms include a desire for exhibition casebacks and concerns about the quality and security of the stamped metal clasps and bracelets, which are frequently described as rattly or underwhelming, though this is noted as a common Seiko trait. Some owners are split on the number of Save the Ocean variations and dislike the cyclops magnifier.
