Does the Citizen BM7620-83M need a battery?

No. The Eco-Drive E111 movement charges from natural or artificial light and holds about six months of reserve when fully charged.

Is 38mm too small for a men's watch?

It wears like a classic dress watch. It suits wrists under about 7 inches well; larger wrists may find it modest.

Yes. It is rated to 10 bar (100m), which covers swimming and showering, but not diving.

Is the crystal sapphire?

No. It uses crystal glass, which is clear but softer than sapphire and can scratch with hard knocks.

The watch on its stainless steel bracelet, a Citizen presentation box and paperwork. No extra strap is included.
