【Hamilton】Standard power reserve of 60 hours! The functional beauty of the 'Intramatic Auto Chrono'

Joining Hamilton's 'Intramatic', which embodies innovative craftsmanship along with the power and passion of auto racing, is the 'Intramatic Auto Chrono' automatic chronograph. Speed, passion, and precision—each aspect is of the highest quality.

"The charm of the 'Intramatic Auto Chrono'

Inspired by Hamilton's first automatic chronograph, 'Chronograph A', the 'Intramatic Auto Chrono' features a stealth black 40mm case. The PVD treatment applied to the case and strap buckle consists of a multi-layer process with a thickness of just one millionth of a millimeter, providing excellent corrosion resistance. It's nice to know it can be used for a long time with its enhanced protective features.

In addition to two sub-dials, it is equipped with a chronograph hand, date display, and tachymeter, offering exceptional practicality. The main body is designed to measure the average speed between two points based on elapsed time, in conjunction with the chronograph hand. While stopped, the tachymeter displays the average speed, and by pressing the lower button once, the chronograph hand returns to the 12 o'clock position.

Functionality is provided by a movement with 28 jewels and a standard power reserve of 60 hours. The design conceals tremendous power, akin to that of a supercar.
