Sold as "Reloj Conmemorativo S-81 Isaac Peral": designed for the Spanish Navy to commemorate the launch of the S-81 Isaac Peral submarine, limited to 250 pieces. Brand spec list: Miyota 8215 automatic, 316L steel case, date with magnifier at 3, 40mm without crown, 10 ATM, screw-down crown and caseback, mother-of-pearl dial, unidirectional 120-click bezel, 316L steel bracelet with butterfly clasp, luminous indices and hands, sapphire. The store files it under "descatalogados" and "últimas unidades" (last units) but still sells it. Crown guards and the oyster-style bracelet are from photos. Same 40mm diver case and movement as the brand's other commemorative watches (Guardia Civil, Infantería de Marina, La Legión); none of them is sold as a plain catalogue model, so each is its own model.
