Known for robust constructions and practical designs, the brand produced watches intended for real use — diving, travel, and everyday adventure — rather than purely dress aesthetics. The Super 28 stands out as a true statement piece. Its oversized 43 mm case was highly unconventional for its era, making it instantly recognizable and ahead of its time. The rotating outer bezel, engraved with world cities such as New York, Tokyo, Buenos Aires, and Paris, paired with the inner rotating ring, reflects the fascination with global travel and jet-age exploration of the period. The black dial, generously sized luminous markers, and bold hands ensure excellent legibility, while the date window adds daily practicality. On the case back, the engraved “Waterproof – Stainless Steel Back” marking and emblem reinforce its tool-watch identity and utilitarian roots. Today, the Mortima Super 28 is appreciated by collectors for its strong presence, mechanical soul, and unmistakable vintage personality. It is not just a watch, but a reminder of an era when timepieces were built as instruments — honest, rugged, and ready for the unknown.
