Well designed field watch. Crisp design. Good value for the money for a Mechanical Chrono. Like the two prong clasp and leather watch band. Fits comfortably on the wrist. Hamilton focused on the quality with this watch.

Really great watch that can be worn everyday without hesitation. The band is really nice and the watch has a great feel to it.

The watch is of the highest quality, has a beautiful retro feel, operation, and heritage. It has proven accurate to within 1 sec per day, which is outstanding for a manual watch. The strap is comfortable and also of great quality. It accommodates my larger 7.5" wrist, ending on the 2nd from the last fastener points. I am very happy I purchased this watch for myself.
