Mostly I am interested in mid-20th-century chronometers, which do indeed tend to be simple 3-hand watches, manual winding
and slow beat. Here are a few others of possible interest:
circa 1948 Audemars Piguet, 37mm, Valjoux VSZZ movement:
circa 1970s IWC Yacht Club, 36mm tonneau, Cal. 89:
circa 1950 Zenith Cal. 135, 36mm diameter:
circa 1958 JLC Geophysic, 35mm, Cal. 478/BWS/br:
circa 1948 Omega, 36mm Cal. 30T2SCrg:
