Discover the Jazzmaster Open Heart Auto 42mm H32705640 watch, made for men's wrists. It captivates at first glance with its round case in polished and brushed stainless steel. The case measures 42 mm in diameter and 11.45 mm in thickness. A flat sapphire crystal sits atop the dial, shielding it from impacts, and features an anti-reflective coating for effortless readability. At 3 o'clock, a grey crown with the brand's signature embossed H and a knurled texture ensures a secure grip for setting the hands. Finally, the watch features a screwed and engraved case back providing 5 ATM water resistance, with a transparent opening that reveals the movement's inner workings.

The Dial

This elegant dial enhances the beauty of this timepiece. Round in shape, it showcases a midnight blue background with white-toned dots evoking a starry sky. Along the edge, a minute track and gold lance-shaped hour markers ensure precise timekeeping. Together, these markers are swept by the three yellow gold-colored hands at the center. The slender seconds hand counts the elapsed seconds, while the long and short hands indicate the minutes and hours. These last two are dauphine-style and coated with a white luminescent treatment, as are the hour markers, for enhanced readability in low-light conditions. The dial also features a skeleton finish that offers a partial view of the movement's mechanics. Finally, at 6 o'clock, the mention "Swiss Made" is printed, and at 9 o'clock, the logo, brand name, and movement type are inscribed as a signature.

The Movement

This watch houses the in-house H-10 automatic movement. This caliber, based on the ETA C07.611, beats at a frequency of 21,600 vibrations per hour and features a Nivachron™ hairspring for outstanding resistance to magnetic fields. This Swiss mechanism is equipped with 25 jewels to minimize friction, ensuring stable performance and vibration resistance. Reliable and robust, it delivers a power reserve of 80 hours.

The Strap

This watch is available with two strap options that you can select from the drop-down menu. Each is fitted with a quick-release system and features a width of 22 mm with a 20 mm buckle.

The first strap is crafted in calfskin leather, giving it exceptional suppleness. Durable and refined, it features tone-on-tone stitching on a blue surface that perfectly complements the dial. It will elegantly adorn your wrist while ensuring all-day comfort. Its pin buckle makes it easy to put on and take off.

The second strap is crafted in stainless steel with brushed links on the surface and polished edges. Sturdy and eye-catching, it will elevate and complete your everyday style. It ensures optimal wearing comfort, and its silver tone pairs effortlessly with any look, bringing a refined touch to every occasion. Its butterfly deployant clasp makes it easy to adjust to your preference.

Water Resistance

With water resistance of 50 meters - or 5 ATM in standard watchmaking terms - this timepiece can handle the occasional splash without missing a beat. You can wear it in the shower from time to time, but to preserve the movement's accuracy and longevity, our watch specialists strongly advise keeping it away from prolonged contact with water - no baths, pools, or the sea. In short: no swimming, no diving, and no extended immersion.
