This aviation watch is my first automatic watch and I am extremely pleased with it. I have a large wrist around 8”, and it is sized appropriately. I love the movement and the dial. The green is darker than pictured which I like, although some additional photos in other lighting conditions would have been useful. The lumenis relatively dim, but that’s not a dealbreaker for me. Overall I’m very happy with the purchase.

The watch is great. The nylon band though, needs to be about 13 mm longer. Mine doesn't reach the next loop.

The watch was a birthday gift for my husband. He mentioned that this is the watch he was liking to get. He was happy beautiful watch. He is enjoying it! He mentions the wonderful second hand sweep! I researched this watch with very little price variance however my purchase from Hamilton co. directly made it an educated experience.

I am enjoying my new Khaki Aviation Pilot Day Date Automatic very much. From the clean dial appearance to the day date complication, it all works well together. And I am particularly enjoying the 80 hour power reserve too.

Great watch, there are a few sharp edges (buckle, inside of lugs). Alot of watch for the money. leather strap could be nicer, but again, for the money, great watch. Polishing way above price point!!
