Stunning Functionality and Beauty

The Seiko QM-11 Quartz Marine Chronometer is like a piece of living history from a time when people cared to create items of stunning functionality and beauty. The photos don't do it justice. When you handle this chronometer, you immediately feel its quality and precision. It's breathtaking.

Useful for the autonomous navigator or prepper sailor who doesn't want to rely on the GPS grid or radio services, giving a feeling of security for the celestial navigator.

Accurate to 3 seconds a month in good conditions and rated to -10 to 50 C.
3 D size batteries last a year and the internal battery lasts 40 hours to allow for battery change.

Thank you American Nautical Services for your friendly and professional service.
