Few weeks ago I bought a watch I was looking for for a long time, the Khaki Mechanical green dial:
For the money it's good but side by side with a Longines W.W.W. you can see the quality difference: the lume of the Hammy is very weak, almost non existant on the dial, while the Longines is strong, not Seiko strong but like a Speedmaster. The sapphire crystal has a blueish tint and reflects a lot of light, while the AR coated of the Longines is transparent and hold better reflexes.
Also, out of the box it gained 20 seconds per day, I had to regulate it and right now it's about +5 sec/day, like my Longines, so I would say the latter are better adjusted than Hamiltons.
Having said that the design is amazing and I like that watch very much, I am looking for an original military issue one as well.
