Expect plenty of gold, serious movements and intricate dials.

It’s a faithful interpretation of the brand’s first Defy model—with a few upgrades.

The 37 mm watch has a titanium barrel-shaped case with a striking black-and-white dial.

Purchase either of the limited-edition timepieces and, for a brief period of time, you can feel like an astronaut.

The 18 rare and sought-after timepieces will be sold exclusively online.
