## Overall Watch Rating: 6.6/10.0

**Material Metric (7.5/10.0)** - Solid stainless steel construction with mineral crystal offers reliable vintage durability, akin to well-preserved Seiko divers from the same decade.
**Complications Metric (6.8/10.0)** - The integrated moonphase adds elegant functionality beyond basic timekeeping, performing on par with affordable Swiss moonphase models.
**Movement Metric (6.5/10.0)** - The Cal. 2870 quartz delivers exceptional accuracy and low maintenance, matching the reliability of modern ETA quartz calibers.

**Versatility Metric (6.0/10.0)** - Suited for formal and collector occasions with its dressy vintage vibe, it holds up reasonably like classic Omega dress pieces.
**Brand Metric (5.2/10.0)** - Citizen's reputation for accessible innovation places it solidly in the mid-tier, on level with Hamilton's consistent performer status.
