PRECISION IN EVERY DETAIL

Lab-grown diamond bezel sets this Daytona apart. Real diamonds, ethically created, visually identical to mined stones.

40mm case in 904L stainless steel, the same alloy trusted by leading Swiss manufacturers.

Oyster-style bracelet with polished center links reflects light alongside the diamond bezel.

Sapphire crystal matches the diamond's scratch resistance, keeping the entire face pristine.

At 142g, every gram carries the presence of a true luxury build.
