Which is better for swimming?

Both are rated to 10 bar (100 m). The Chandler is explicitly rated for swimming and snorkeling, but its leather strap will degrade in water. The AQ4091-56M's titanium bracelet handles water better.

Is the AQ4091-56M worth the extra money?

If you want titanium, sapphire and ±5 sec/year accuracy, yes. At $2,378.97 versus $145.00 as of November 7, 2026, you pay about 16 times as much for those upgrades.

The AQ4091-56M should hold up longer: sapphire and Duratect-coated titanium resist scratches, and the movement is rated to ±5 sec/year. The Chandler's mineral crystal and leather strap wear sooner.

Which is better for a formal setting?

The AQ4091-56M. Its 40 mm titanium case and bracelet with a platinum-tone finish read as dress/formal. The Chandler's brown dial and leather strap are casual.

Do either need battery changes?

No. Both are Citizen Eco-Drive solar movements. The AQ4091-56M runs about 7 months on a full charge; the Chandler's reserve is not specified.

Which is easier to buy?

The Chandler: 4 stores price it new, with a best price of $145.00 at eBay as of November 7, 2026. The AQ4091-56M has only 2 stores, and Japan shipping can mean customs delays.
