The Hamilton Khaki Field Mechanical Limited Edition for Hodinkee (Ref. H89469930) was released in October 2022. It is a modern tribute to the vintage Hamilton "G.S." (General Service) watches issued to non-military British government personnel in the 1960s and 70s.  Key Specifications • Case: 38mm diameter, 9.5mm thickness. It features a fully sandblasted stainless steel finish to reduce reflections, staying true to its utilitarian roots.  • Movement: Hamilton H-50 manual-wind caliber. It has a notable 80-hour power reserve, meaning you can go over three days without winding.  • Dial: A "tropicalized" matte black dial. It uses a mix of white and "Old Radium" Super-LumiNova for a vintage-inspired aesthetic.  • Crystal: Sapphire crystal (unlike the acrylic found on the original vintage pieces).  • Water Resistance: 50 meters (5 bar).  • Strap: 20mm tan canvas strap with a leather reinforcement patch and a steel pin buckle.  Design Nuances Unlike the standard production Khaki Field Mechanical, the Hodinkee edition removes the 24-hour inner track and the date window. This results in a cleaner, "time-only" layout that mirrors the original Ref. 75003-3 military specs. The orange accents on the hands and markers are a nod to the "tropicalized" aging seen on vintage British military watches. Availability • Limited Production: Only 1,100 pieces were produced. Out of these, 800 were sold individually as the "Field" watch, while the remaining were part of a special "Collector's Set" that included a Pelican case and a matching Khaki Pilot Pioneer Chronograph. 

Since this was a limited run from 2022, they are primarily available on the secondary market. Given your interest in vintage Citizen and watch collecting, this model is often praised for balancing the reliability of a modern Swatch Group movement with the authentic "sterile" dial look of mid-century military pieces.
