Zenith Marina Militare

About this reference

The Zenith Marina Militare reference 4528 is a manual-wind chronograph produced during the late 1960s and early 1970s. This specific reference is distinguished by its 18k yellow gold and stainless steel construction, featuring a 37mm case and a silvered dial with tachymeter and telemeter scales. Collectors value the model for its historical association with the Italian Navy (Marina Militare) and its use of the caliber 146DP, a high-grade movement produced by Martel before Zenith’s transition to the El Primero. Due to limited production numbers compared to standard steel variants, the 4528 is considered rare. On the secondary market, these timepieces typically trade between $6,000 and $10,000 depending on the preservation of the gold bezel and dial condition. A notable production detail is the "A. Cairelli Roma" signature found on select examples, indicating distribution through the Roman retailer for military personnel.
