Watch Jazzmaster Open Heart Auto 36mm H32215170

The Watch

Hamilton is a brand founded in 1892, celebrated for its reliable, elegant, and high-performance timepieces. With exceptional craftsmanship, it has carved out a distinctive place in the watchmaking world and won the hearts of discerning watch enthusiasts. Today, we invite you to discover one of the brand's flagship models: the Open Heart Auto from the Jazzmaster collection. This watch is chic and understated, with stunning details that are impossible to overlook. It features a beautiful round stainless steel case measuring 36 mm in diameter and 10 mm thick, perfectly proportioned for women's wrists. The case combines subtle mixed finishes that enhance its elegant design - a brushed satin finish on the curved lugs and a polished finish on the case sides. A flat anti-reflective sapphire crystal protects the dial against scratches and damage. On the right side of the case, a knurled crown is used to set the hours and minutes. Signed by the brand and featuring a knurled texture, it adds a refined touch. The caseback features a circular transparent aperture through which the movement is visible - you can admire the oscillating rotor, part of the gear train, and the rotor specially engraved with the Hamilton logo. Also screw-down, it ensures water resistance of 5 ATM.

The Dial

Blending innovation with modernity, the classic elegance of this model's dial makes it truly irresistible. Round in shape and featuring a powdery pink hue, the dial showcases a charming sunray finish complemented by a skeleton finishing. The outer edge is lined with a minute track alongside applied drop-shaped hour markers. These are indicated by two dauphine hands with a luminescent coating for easy reading in low-light conditions. A slender seconds hand with a lance-shaped counterweight completes the display. The hallmark of this dial is its skeleton finish, which reveals the movement beneath and lends it a distinctly elegant air. The finishing touch is the brand signature, noted alongside the movement at 9 o'clock.

The Movement

This automatic watch is powered by the H-10 caliber, delivering an 80-hour power reserve. This Swiss-made caliber is based on the ETA C07.611 and features 25 jewels with a maximum daily variance of approximately 15 seconds. Running at a frequency of 21,600 beats per hour (3 Hz), it is equipped with a Nivachron™ hairspring.

The Bracelet

Hamilton paired this model with a stainless steel bracelet. It features 5 rows of links alternating between brushed and polished finishes that match the case, creating a beautifully cohesive look. The bracelet measures 18 mm wide at the lug end and 16 mm at the butterfly deployant clasp.

Water Resistance

This model offers water resistance of 5 atmospheres, or 50 m. Stunning to look at and built to turn heads, this timepiece doesn't sacrifice resilience for beauty. You can wear it in the shower - though the Ocarat team recommends keeping it safely on the edge of the sink to preserve its brilliance and integrity over the long haul. As for swimming and diving, we strongly advise against submerging this watch, as doing so may cause damage and lead to costly repairs.
