The Hamilton Khaki X-Wind Chronograph family (the one, which is listed on their website as a member of a larger Khaki Aviation family of military-themed watches) was recently updated with a limited edition collection (including a version with black dial, pictured, ref. H77766331.) Being ahem limited to ahem just 1999 pieces, it will never become a true rarity (well, maybe in fifty years or so), but I must admit that this little guy still looks nice. Featuring all the usual stuff, like a true chronograph movement and their famous drift angle calculator, the new watch differs from the rest of the pack with its new color combinations and a slightly reworked dial.

Look who has just got a sibling! The military-styled Khaki Pilot (ref. H64715885) that was first revealed back in early 2010 has just received a younger brother. Called Hamilton Khaki Aviation Pilot Chronograph (ref. H646666735), the new automatic "aviator" from the legendary brand nicely fits a bullet-proof ETA Valjoux 7753 movement into the same mid-sized body of a (sort of) tactical timekeeper.

The new Hamilton Khaki Aviation X-Patrol (refs. H76556331, H76556131, and H76566751) looks like an evolution of the stealthy Khaki X-Mach Pilot that was presented almost exactly three years ago in February, 2009. The difference between the two? Well, preserving all the controls and being powered by virtually the same movement, the new version now lets you convert nautical miles into statute miles and back. And the watch has also become smaller.
