The Khaki Field Mechanical Power Reserve 40 mm watch is superb! The design could not be nicer. The gauge showing winding energy reserve is fun. The sandblasted stainless steel case and bracelet are beautiful. And the domed sapphire crystal, with AR coating, is beautifully done. All-in-all just a superb watch. Nicely done, Hamilton! My only complaint is with the sizing of the metal watch bracelet. I carefully measured my wrist, using Hamilton’s downloadable measuring tool. And the watch was sized, with the extra pieces included in the box (thanks). But the size was not even close. I had to have it resized at a local jewelry store. Hamilton should not bother to size the bracelets unless they can get closer to the customer’s measurement.

This is an awesome watch. Could not be happier with my purchase. Classic styling of a Hamilton field watch with the convenience of the visual power reserve which does not detract from the overall visual styling. The watch band is super comfortable and fits exceptionall well. I can almost forget that I'm wearing it - I checked my wrist and I am!
