Does the Breitling Emergency really send a distress signal?

Yes. Pulling the crown deploys an antenna and the watch transmits on the 121.5 MHz aviation emergency frequency, which is monitored by overflying aircraft and rescue services. It is a backup beacon, not a satellite messenger, so it does not give your position.

How is it different from a normal Breitling?

The Emergency adds a self-contained transmitter module with its own battery on top of the timekeeping movement. That module is why the case is so large and why servicing is more involved than on a standard chronometer.

Is the titanium version worth choosing over steel?

Titanium cuts weight noticeably on a watch this big, and the DLC coating adds scratch resistance. The trade-off is a darker, less shiny finish than polished steel.

Can I wear it every day?

You can, but the case is tall and wide, so it suits casual wear better than a shirt cuff. Many owners keep it as a dedicated travel or offshore watch.

What should I know before using the beacon?

Deploying it is a real emergency declaration in many countries, and misuse can carry penalties. Check local rules and register the beacon where required before relying on it.
