The History and Military Heritage of Khaki Field
The Hamilton Khaki Field Mechanical has a history that few watches can match. Hamilton was the official watch supplier to the US Army for decades, and the Khaki Field is the direct successor to those military timepieces. This isn’t just marketing: it’s history documented in military museums and private collections around the world.
The H-50 calibre is a Swiss-made manual-winding mechanical movement with an 80-hour power reserve. An 80-hour power reserve is exceptional for a manual-winding mechanical movement. Most classic hand-wound mechanical movements have a power reserve of 40–50 hours, which means they need winding every two days. With the H-50, you have three full days before you need to wind it.
The 38mm case is nowadays a ‘counter-trend’ size in the best possible sense. Whilst the market is flooded with 42–44mm watches, the Khaki Field retains its original 38mm size, which sits perfectly on medium and small wrists, and looks more elegant with a suit than any large watch.
Case: 38mm Swiss-made, priced at €449
Construction: A 38mm Swiss-made watch for €449 is one of the most important factors to consider when choosing a high-quality watch or accessory. Well-informed buyers always research these details before making a decision, and the difference between a good choice and a disappointing one often lies precisely here.

Sapphire crystal in a watch at this price
A watch’s crystal is the factor that most determines its day-to-day durability, and yet it is the one most overlooked by first-time buyers. The Mohs hardness scale ranks materials from 1 (talc) to 10 (diamond): synthetic sapphire has a hardness of 9, treated mineral glass (Seiko’s Hardlex) around 7, and standard acrylic a mere 3.
In practical terms: with a sapphire crystal, you need a diamond to scratch it. With standard mineral glass, keys in your pocket or a knock against a hard surface will leave marks. With acrylic, almost any friction will scratch it, although it does have the advantage of being able to be polished with polishing paste. For a watch you’ll wear every day for years to come, sapphire isn’t a luxury but an investment.
The good news is that sapphire crystal is now available in affordable watches: the Tissot PRX (€575), the Hamilton Khaki Field (€449) and the Casio Edifice EQB-1200 (€229) all feature sapphire crystal. For under €200, you’ll mainly find mineral glass or Hardlex, both of which are adequate for everyday use provided you take reasonable care.
