Tudor Submariner Reference 7928

Partially verified

This late-series Tudor Submariner, reference 7928, is identified by the vendor as a 1967 production year. The watch features a stainless steel case measuring 40mm in diameter, housing a self-winding movement. The dial is classified as a Mk7 variant, which includes the Tudor rose logo. A distinguishing feature of this particular example is the darkening of the luminous material on both the dial indexes and the hands, creating a specific visual aesthetic. The watch is paired with a Jubilee-style bracelet, described as a "Hecho en México" variant, which was originally produced for the North and South American markets. The rotating bezel insert exhibits a faded finish with a 'fat font' numeral style. The auction description reports that the watch has been fully serviced by their watchmaker.
