Vintage Sheffield Automatic Diver's Watch with Date Function

This is a vintage Sheffield automatic diver-style wristwatch, likely dating from the mid-to-late 1960s. The watch features a stainless steel case with approximately a 36-38mm diameter, exhibiting significant signs of wear and age. It utilizes a rotating black bi-directional bezel with silver-toned scale markings and a serrated edge, which shows extensive paint loss and scratching throughout. The champagne-colored dial displays a radiating sunburst pattern and includes rectangular hour markers, a date window positioned at 3 o'clock, and the Sheffield 'S' logo. The dial text reads 'AUTOMATIC,' 'SHOCKRESISTANT,' and 'WATERPROOF.' A domed acrylic crystal protects the face, though it appears heavily clouded and scratched. The watch is fitted with a vintage dark brown or black tropic-style leather or composite band with a textured 'diamond' pattern and perimeter stitching; however, the strap is in poor condition, appearing brittle with significant dirt accumulation and surface deterioration. There is visible corrosion and pitting on the lugs and the case back, indicating heavy previous use and exposure to moisture. While Sheffield was a mass-market assembler, their automatic movements from this era often utilized Swiss-made parts, making this a classic example of entry-level mid-century dive watch design.
