How do they do it?

I know that many Breitlings are thick.

However, there are quite a few, that have a really slim profile. And I like it. It allows for a larger watch to look and wear quite small, but with great visibility and wrist presence.

But curious how they do it. The watch I am wearing today has a GMT, Date and 300M water rating.

Everything other brand, from what I can tell, says the thickness of the case is due to the thickness of the movement and the requirements based on depth rating.

For example the Submariner is slightly thicker than the 116710 GMT because of the water rating.

Curious if anyone has any knowledge on this.

Thanks,
