About This Reference
The 220.12.41.21.03.005 brings the latest-generation Aqua Terra small seconds layout together with a sun-brushed blue-grey teak-pattern dial that shifts tone with the light — cooler in shade, warmer in direct sun. The opaline small seconds subdial at 6 o'clock sits within a rhodium-plated ring, and the sandblasted minute and seconds tracks across the dial add layered texture that rewards a closer look. Rhodium-plated hands and indexes filled with white Super-LumiNova ensure legibility day and night. Presented on a blue structured rubber strap with grey stitching, it carries the sporty versatility the Aqua Terra is known for while the calibre 8916 inside — METAS-certified and resistant to magnetic fields above 15,000 gauss — delivers the same 60-hour power reserve and precision as its bracelet-mounted counterpart.
