Casio WS-1700H-8AV digital sports watch 100m 48.60mm

Moon-phase graph for outdoor use

The Casio WS-1700H-8AV adds a moon-phase graph to a standard digital sports watch, giving hikers and night-fishing enthusiasts a quick visual reference for lunar cycles without needing a phone app. Its 100m water resistance supports swimming and surface snorkelling, while the quartz movement keeps time without daily winding.

Resin case and strap with buckle clasp

The all-resin construction — case, crystal and strap — keeps the watch light on the wrist and resistant to salt-water corrosion, and the buckle clasp secures the band through vigorous movement. A fixed bezel eliminates rotating parts that could snag on gear, and the grey digital display shows month, day and date alongside dual-time readouts.

48.60 mm case thickness defines wearability

At 48.60 mm thick the case sits high on the wrist, which can catch on jacket cuffs or feel bulky under tight sleeves, so buyers who need a low-profile fit for office shirts or slim wetsuit seals should consider a thinner model. The resin crystal resists shattering but scratches more easily than mineral or sapphire glass, so expect visible wear after repeated rock contact.
