Daily Solar Watch

The Citizen Eco-Drive BM7631-87M is a 41 mm stainless steel watch powered by light. Its solar movement runs roughly six months on a full charge, removing the need for battery changes. A blue dial with bar markers and a date window sits under mineral crystal. The solid bracelet secures with a deployment clasp for a clean wrist presence.

Work And Weekend Wear

Suits professionals wanting one watch that moves from desk to dinner without winding or charging cables. The 100 m water resistance handles swimming and daily splashes with ease. Buyers who need a screw-down crown for serious diving or a sapphire crystal for maximum scratch resistance should look elsewhere. The fixed bezel also means no elapsed-time tracking for sports timing.

41 mm Case Decision

The 41 mm diameter and 9.7 mm thickness decide whether this sits right on your wrist. Larger wrists may find it modest; smaller wrists may feel it bulky. That single proportion determines if the Blue Glow Night becomes a daily staple or a drawer occupant.

この商品に関する質問

How much light does the Eco-Drive Caliber E111 need to keep running all day?

The solar movement charges from any light source and holds roughly six months of power reserve once fully charged.

Does the 41 mm stainless steel case require a special tool to adjust the bracelet?

The solid stainless steel bracelet uses a deployment clasp with push-button release, so links can be sized without proprietary tools.

Will the 100 m water resistance and mineral crystal hold up if I keep wearing my older leather-strap watches in rotation?

Yes — 100 m water resistance and a screw-down case back protect the movement during daily wear, while the mineral crystal resists knocks when you switch between watches.
