How do you change the strap on the Hamilton Khaki Aviation H77656713?

Use a spring bar tool to gently lift the pins (spring bars) that anchor the strap to the case. Insert the tool tip under the pin, apply slight upward pressure, and remove the strap. Insert the new strap by first aligning one lug, then the other, ensuring the pin is firmly in position.

How long does a leather strap last on the Hamilton Khaki Aviation H77656713?

Natural leather ages with character, developing patina: this is not deterioration, but rather aesthetic evolution of the watch.
