I was looking for a daily wear watch that wasn't too large and I could wear it as a complement to whatever I am wearing. This is stylish, simple, sleek and hits all my marks. I bought an additional strap to also complement my wardrobe. Love how easy it is to change the straps and Hamilton sent me the needed tool for free when I bought the second strap!

Gifted to our son for college graduation. He was very happy and loved the black face on leather band. Great looking watch and value. I’ve bought vintage Hamilton’s in the past and love the quality

I've only had the watch for a day, and am glad I purchased it. It's beautiful. I've been looking at it for 9-10 months and after achieving a professional goal, the watch is my reward. It's my first new watch in about 17 years.

I love my new Hamilton Field King watch. Great feel and look!! Should be very durable and be something that can be used by my children and grandchildren after I am done using it.

Great watch at a good price. This was my first Hamilton, but it won't be my last as the fit and quality are superb. You can never go wrong with a brand with the lineage of Hamilton.
