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.

Grand Seiko SBGR321

Grand Seiko SBGR321 owners and reviewers widely praise its attractive design, compelling dimensions, and robust movement. The watch features sharp case lines with contrasting brushing and polishing, a 40mm steel case that provides presence without bulk, and 100m water resistance. Its sunburst blue dial, inspired by the dawn sky over Mount Iwate, showcases Grand Seiko's signature finishing on applied markers and hands, with a red-tipped seconds hand. The 9S65 automatic movement is noted for its precision, running within specifications, with one source reporting a +5 to -3 seconds a day rate and a 3-day power reserve. A blue rotor with a crimson rim, also inspired by Mount Iwate, is visible through the display caseback. On balance, owners and reviewers rate the Grand Seiko SBGR321 highly for its exceptional finishing and compelling blue dial design at its price point.
