Jazzmaster Open Heart Auto 40mm Watch H32675551

The Watch

Hamilton is a watchmaking brand that masterfully blends American spirit with Swiss precision. Its international reputation has been built on bold, contemporary designs that captivate both men and women. From the iconic Jazzmaster collection comes this stunning Open Heart watch, featuring a case crafted in stainless steel. With a silver tone and a brushed/polished finish for added sophistication, this round case measures 40 mm in diameter and 11.05 mm in thickness - proportions perfectly suited to men's wrists. A flat sapphire crystal protects the dial from everyday scratches and impacts, while an anti-reflective coating ensures effortless readability. A crown at 3 o'clock provides easy access to time-setting functions. Finally, the transparent screw-down caseback offers a captivating view of the movement while maintaining water resistance to 5 ATM.

The Dial

This dial features a silver-toned base enhanced by a sunray finish and a skeleton design that gives this timepiece its distinctive identity. A minute track runs along the perimeter with black graduations. Gold-toned indexes mark the hours and are swept by two dauphine hands positioned at the center of the dial to display hours and minutes. They feature luminescent treatment for easy readability in low-light conditions. Note that a gold seconds hand handles the seconds. Finally, the brand name and logo are positioned at 9 o'clock.

The Movement

This watch is powered by a Swiss-made automatic movement - specifically, the H-10 caliber, which ensures precise timekeeping down to the second. With 25 jewels to minimize friction, this movement offers magnetic resistance thanks to its Nivachron hairspring and delivers a power reserve of 80 hours. It beats at a frequency of 21,600 vibrations per hour.

The Strap

Hamilton has fitted this creation with a stunning calfskin leather strap. Its rich dark brown color accentuates the chic, vintage character of this watch with a touch of refinement. Tone-on-tone stitching along the edges puts the finishing touch on the design. The strap fastens with an 18 mm pin buckle. Note that the lug width is 20 mm.

Water Resistance

With a water resistance of 50 meters - or 5 ATM in watchmaking terms - this timepiece can handle the occasional splash, but prolonged water exposure is not recommended. You can wear it in the shower from time to time, but to preserve the mechanism's quality and precision, all watch specialists strongly advise keeping it away from baths, pools, and the sea. In short: no swimming, no diving, and no extended contact with water.
