Although field watch is somewhat ambiguous and meaningless designation, I think this RAF Hamilton could be a perfect working definition. The watch is completely without pretense, function over all other considerations. Mildly undersized for comfort, tritium for legibility, an uncluttered dial, and simple (easily fixable) movement. I long for simplicity in the era of the connected smart refrigerator. This Hamilton supplies that and so much more.
I won’t really go into detail behind the 6B’s history. Militaries needed a specific designation of watch, Hamilton was one of the suppliers. This doesn’t feel like the right time to elaborate on Hamilton’s story, but I’m sure I will in the future. Let’s just say this watch is nice nod to friendly Anglo-American relations. Its case is 36mm with a screw back, tritium, and broad arrow front & center. It’s on a NATO, as all military instruments should be (in my book).
The example sports light surface knocks but really nothing indicating that it was an issued piece with a hard life. That is a rarity. The dial is wholly intact, lume matching and all. The movement, which is pictured, shows nothing out of place. It’s lovely and highly practical addition to any military collection.
