Inspired by Model 23, a head-of-the-art pocket watch that was used by US soldiers during the Second World War, the remarkable design of the Khaki Pilot Pioneer pays tribute to Hamilton's legacy in the fields of Aviation and the army. This sports and refined watch retains its resolutely functional style thanks to its mechanical movement with manual winding, its bidirectional rotating bezel and its prominent winding wreath. Declined with a unique stainless steel or bronze stainless steel case, this 43 mm timepiece is peeled.
