Tudor Oysterdate

About this reference

The Tudor Oysterdate reference 7031 was produced between 1970 and 1971 as part of the brand’s inaugural chronograph series. Collectors prioritize this reference for its 40mm steel case, Valjoux 7734 manual-wind movement, and the "Home Plate" dial configuration, characterized by pentagonal luminous hour markers. Unlike its sibling reference 7032, the 7031 features a black acrylic tachymeter bezel rather than a steel one. Due to a production run lasting only approximately two years, the 7031 is rare on the secondary market. Current market valuations typically range from $35,000 to $60,000 depending on the presence of the original "Cyclops" crystal and the condition of the dial’s orange accents. A notable variant includes the "grey" dial with black sub-dials. In 2023, well-preserved examples with original boxes and papers have commanded prices at the upper end of this bracket at major auction houses.
