DESCRIPTION
This exceptional diver’s watch is limited to just 300 pieces globally. The Alpina Seastrong Calanda features a 42mm recycled stainless steel case, crafted from Thyssen Krupp's certified 100% recycled PureSteel™, known for its maritime heritage and sustainable production. Water-resistant up to 300m (1,000ft), it includes a 60-minute unidirectional bezel and a recycled PET strap. Powered by the Alpina AL-525 Automatic Caliber with 26 jewels and a 38-hour power reserve, it operates at 28,000 alt/h.
