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 5KX

Owners widely praise the Seiko 5 Sports SKX series for its strong lume and comfortable wearability, with many noting its compact feel due to a short lug-to-lug length. The NH36 movement's accuracy varies, with typical performance between +/-5 to 10 seconds per day, though some report better. A lack of screw-down crown and ISO certification are noted drawbacks for its water resistance. Some owners find the bracelet to be of cheaper construction with hollow links, and a few have reported quality control issues. The consensus is that the Seiko 5 Sports SKX series offers good value for its price, appealing to those who appreciate its tool-like nature and iconic lineage.
