The American-based watchmaker has finally introduced a full-fledged flight computer into its product range. The multifunction Hamilton Khaki Flight Timer (ref. H64554431) quartz-powered pilot’s watch was created together with Air Zematt, the Swiss helicopter transport and rescue service.
Probably targeted against similar watches from Japanese watchmakers (I guess, the Hamilton Khaki Flight Timer will have a hard time competing against similarly equipped analog-digital watches from the Swiss-based Breitling that, first, are equipped with superior ETA Thermoline-based SuperQuartz thermocompensated calibers and, second, are just plain better advertised as an elite pilot’s wristwatch of choice,) the new timekeeper is equipped with the ETA E20.373 quartz ebauche.
Although said to be developed exclusively for Hamilton, the movement seems to belong to ETA’s current “Flatline” family of ana/digi quartz movements: namely, the well-known Caliber ETA E20.321. There is no info regarding what modifications were made to the aforementioned caliber, but the Swatch Group appears to move Hamilton to a slightly upper range in its portfolio of watchmaking brands, so I would assume that the E20.373, like some other of their recently introduced “exclusive” ETA movements, features some upgraded mechanical elements that would help it achieve longer lifespan and increase its overall reliability compared to stock E20.321 engines.
Besides the usual stuff, like current time, perpetual calendar, chronograph, UTC, alarm and temperature, the movement that powers this absolutely stunning H64554431 also offers you a personalized logbook that records and stores all necessary information on whole “20 flights and up to 99 landings for each of them.” Now, that’s impressive.
All these functions are operated via the crown, as well as by four push-pieces that are placed at 2, 4 and 10 o’clock.
The movement is hidden inside a rather compact stainless steel case only 40 millimeters in diameter that features a rather peculiar bezel. The latter has the usual 00 – 55 minute markings painted in a counter clockwise fashion.
Another minute track is printed in bold Arabic numerals inside the matte black dial.
Being a very sophisticated device, the watch features a set of LCD displays that display information not only with Arabic digits, but also with some strange pictograms reminding of those from the Predator movie. You will possibly need to thoroughly study the owner’s manual before using this instrument.
The dial is protected from weather and water with a sapphire crystal with an antireflective treatment.
Although also supplied on a black rubber band, as well as brown leather strap with silver dial (ref. H64514551) and stainless steel bracelet (ref. H64554131,) it is the bright-orange rubber strap that makes the watch truly shine.
