Solar Powered Dress Watch

The Casio MTS-RS100D-1AV is a solar powered analog watch built for daily professional wear. Its stainless steel case and bracelet resist corrosion while the black dial with luminous hands and markers remains legible in low light. A fixed bezel and 50m water resistance suit office and light outdoor use.

Sapphire Crystal and Deployment Clasp

Sapphire crystal with anti-reflective coating protects the dial from scratches and reduces glare under bright lighting. The deployment clasp secures the stainless steel bracelet with a single motion and prevents accidental opening. Solar charging removes the need for routine battery changes during ownership.

Verify Wrist Fit and Water Needs

Confirm that a 41.70 mm case diameter matches your preferred wrist presence before ordering. The 50m rating covers splashes and brief immersion but not swimming or diving. Buyers who require deeper water resistance or a smaller case profile should consider other models.

Questions about this item

How often will the solar cell and rechargeable battery need replacement on the MTS-RS100D-1AV?

The solar cell charges the internal battery continuously under light; the sealed power cell typically lasts many years before any service is required.

What limits daily wear first — the 50 m water resistance or the fixed bezel?

The 50 m rating covers splashes and brief immersion; the fixed bezel does not affect water resistance, so the depth rating is the practical limit.

Does the stainless steel case and sapphire crystal make the watch feel hot on the wrist after all-day wear?

The materials stay near skin temperature; the solar movement generates negligible heat, so the watch remains comfortable during extended use.
