What does the reef connection mean?
Oris says the watch is inspired by the work of the Resilient Reefs Foundation, which it describes as an Australian nonprofit working to combat coral bleaching. The brand frames the edition as part of its continuing commitment to the Australian reef, using the product-page line “Our commitment to ocean conservation continues.”
The product page does not state that a purchase contributes a defined amount to reef restoration, report independently measured results, or attribute a specific conservation outcome to this edition. The connection is therefore a stated brand inspiration and support context, not a quantified impact claim.
Bracelet and strap options
Oris lists the watch with a stainless-steel strap and also lists rubber strap options in a 23 mm width. A listed width alone does not confirm compatibility with every third-party strap or establish that all options use identical attachment hardware. Check the specific strap and fitting details with Oris or an authorized retailer before ordering.

The Federation of the Swiss Watch Industry announcement record dated 2024-08-15 identifies the edition as based on the 43.5 mm Aquis Date and gives water resistance as 300 metres. Those figures align with Oris’s 43.50 mm and 30 bar listings; for the complete current specification set, the Oris product page is the primary reference.
