Slide rules: Hamilton Khaki X Patrol

We showcase dozens of Swiss watches, it’s time to give the Americans a go. Hamilton was founded in 1892 in Lancaster, Pennsylvania, USA. The aim has always been to design watches which reflect American spirit with the unrivalled precision of the latest Swiss movements and technologies. 

Hamilton has a strong foothold in Hollywood, with products appearing in 400 films. The brand also boasts a strong aviation heritage dating back to 1919. That was the year in which a Hamilton aeronautical watch accompanied the very first American airmail postal service between Washington and New York. 

To celebrate its 120th anniversary, Hamilton will release the dynamic Hamilton Khaki X-Patrol in June 2012. This sophisticated chronograph integrates the new H21 calibre -  an upgraded ETA Valjoux 7750 automatic chronograph - noted for its accuracy and extended power reserve of 62 hours. On board is a unique mechanical conversion facility to give accurate equivalents of a selection of units in either metric or imperial systems.

Instrument panel as slide rule

The Hamilton Khaki  X-Patrol does look very much like a cockpit instrument panel and its ability to convert distances in miles (nautical or statute) and kilometres, heights or altitudes in feet or metres, volumes in gallons and litres, as well as weights in pounds and kilograms simply by using a turning bezel should be enough to delight any ardent number cruncher. 


Conversions are simple to make, through unscrewing the easy-to-grip crown at 9 o’clock and positioning an arrow for the first unit of measurement on the outer bezel scale. The appropriate equivalent is then visible on the inner scale. Once the reading is completed, the crown can be pushed back into place and re-screwed to secure it until required again. Three round chronograph discs, gravitating to the left-hand side of the dial keep track of hours, minutes and seconds, operated via push buttons at two o’clock and four o’clock.

Designed to make a difference

In a choice of black or silver dials with contrasting reflectors, the watch comes on a black leather strap with white stitching, a sporty black rubber attachment, or a metal bracelet.

To reflect the aviation theme, on the reverse is a propeller-inspired design, offering a view of the automatic chronograph movement in action. Water resistant to 10 bar ensures that this watch is at home in all environments, airborne or otherwise. As for pricing, the watches are expected to be around $1,295 on a leather strap or $1,345 for the watch on rubber or a metal bracelet.
