This impressive Minerva split-seconds chronograph from the 1940s combines technical brilliance with the aesthetic elegance of early military timepieces. Powered by the Rattrapante caliber Valjoux 55 – one of the most technically sophisticated movements of its era – this watch leaves even seasoned collectors in awe.
The 42 mm case is ultra-rare for the period and delivers a powerful presence on the wrist.
The absolute highlight is the mesmerizing dial, featuring a rare tropical patina in a deep aubergine hue – a unique aging process developed over decades through sun exposure and other factors. The large Arabic numerals and rare cathedral hands retain their original luminous material, whose warm patina perfectly complements the tropical surface.
The two oversized sub-dials provide visual balance. The dial is in outstanding condition, captivating with its depth and unmistakable character.
This Minerva is not only a technical masterpiece but also a relic from an era when precision could save lives. Its beauty, rarity, and historical significance make it a true gem for collectors and lovers of vintage split-seconds chronographs.
