Omega’s 2023 Aqua Terra Worldtimer release comprised three references: two green-dial stainless-steel watches, offered on rubber or a steel bracelet, and a monochromatic grade 2 titanium model on a black rubber strap. Monochrome Watches reported that all three share a 43 mm case, 150 m water resistance and calibre 8938. Its euro prices at launch in May 2023 ranged from €11,500 to €13,300; those historical prices do not establish today’s pricing or availability.

How do the green steel and titanium versions differ?
Green steel: rubber strap or steel bracelet
The two stainless-steel references share a green ceramic bezel and sun-brushed green dial with the Aqua Terra’s striped pattern, as described by Monochrome Watches. Their practical distinction is the supplied configuration: reference 220.32.43.22.10.001 pairs the watch with an integrated green rubber strap, while 220.30.43.22.10.001 comes on a three-link steel bracelet.

Monochromatic grade 2 titanium

The city ring uses London in red as the zero-offset reference, while Bienne, Omega’s Swiss home city, represents Central European time.
