Hamilton Khaki Aviation Converter Auto ChronovsanOrdain Model 1 Precious Metal

The Hamilton Khaki Aviation Converter Auto Chrono is widely described as a large 44mm pilot's watch with a functional slide rule bezel. Reviewers note its well-finished steel case, featuring a robust satin-brushed finish with polished accents and chamfers, and a legible blue sunray dial with applied Super-LumiNova markers and old-fashioned hands. It is powered by the H-21-Si automatic chronograph movement, an upgraded ETA-based caliber with a silicon balance spring for anti-magnetic properties, offering a 60-hour power reserve. The watch is rated to 100m water resistance and features a bi-directional slide rule bezel with graduations printed under K1 mineral glass for scratch protection, which is easy to manipulate due to its deeply notched steel design. Some find the slide rule bezel complicated to use without a manual. One owner notes its character does not appeal as much as other slide bezel chronos.

The anOrdain Model 1 Precious Metal is described as dressy with a solid build, though some owners desire more pronounced case chamfers to better define its shape. The galvanized gold and rhodium dials are noted as great, but one owner prefers anOrdain's signature lacquer dials for a precious metal version. The watch features a 38mm stainless steel case with 50 meters of water resistance and an in-house regulated ETA 2824-2 movement with a 38-hour power reserve. The 18mm lug width is also flagged as a drawback by one owner. Overall, owners find the anOrdain Model 1 Precious Metal to be a dressy watch with a solid build, though opinions are split on the dial and case finishing for a precious metal offering.
