I was expecting a basic field watch and was surprised by how beautiful and well finished is was. It ha hardly deviated by more than a second in a week.

The watch is great. It’s my daily wear. Very comfortable, I hardly know I’m wearing it, I only wish I’d gone for one with a date complication as I do miss that at times, which is obviously not a problem with the watch. It keep’s excellent time and seems to be extremely well made. Will most certainly be buying another Hamilton.

I chose this model as I have slim wrists. I had the strap changed from the NATO to a standard leather strap, which makes the overall profile a bit better for my wrist. It's my first "quality" watch and I'm pleased with the overall build. Hoping for many years of use.
