Uncle's notes The Hamilton Khaki Field Auto is a very popular piece, and I've been inundated with requests as I've started to roll out more Hamilton options. Featuring the famous Hamilton H-10 movement, it offers that classic Hamilton field watch look with an amazing 80-hour power reserve. The one downside, as is often the case, is the lack of bracelet options. Given the similarities to the Murph, I decided to release the same options - an Executive and a Senator. What's included One Jubilee-style bracelet, one pair of end-links, and one pair of spring bars Specs Taper: 38mm: 20mm to 16mm 42mm: 22mm to 18mm Length: 175mm Min length after adjusted: 38mm: 115mm 42mm: 125mm Buckle: 316L Stainless Steel Solid Milled Clasp Thickness: 3.78mm Net Weight: 38mm: 71 grams 42mm: 80 grams Finish: Brushed/Polished Spring bar diameter: 1.78mm Lug end style: Solid Curved End Adjustment type: 6 removable links-- screw type adjustment Micro-adjustments: 3 Material: 316L Stainless Steel, all solid links (solid end links)
