Which is better for everyday wear?

The Bianca EW5602-57D, because its sapphire crystal resists scratches better and its plain dial suits daily use. The FE1147-79P is the dressier pick for evenings and occasions.

Which one lasts longer?

Both use Eco-Drive light-powered movements that never need a battery, so movement life is similar. The Bianca has the edge on durability because sapphire crystal is much harder to scratch than the FE1147-79P's mineral crystal.

Is the Bianca worth the extra money?

At $356.25 at Amazon versus $320 at eBay for the FE1147-79P as of November 6, 2026, the roughly $36 gap buys sapphire crystal and a lighter, smaller case. If you want crystals and a date, the FE1147-79P is the better value.

Which is better for a small wrist?

The Bianca at 21.5 mm is the safer fit for a narrow wrist. The FE1147-79P at 30 mm wears noticeably larger.

Do either need a battery?

No. Both are Citizen Eco-Drive watches charged by any light, so neither needs a battery replacement.

Can I swim with either watch?

Both are rated 50 m, which covers swimming and showering but not diving or snorkeling.
