Jazzmaster "Open Heart" Auto Watch H32705551

The Watch
This men's watch, featuring an elegantly luminous grey dial with an open-heart movement display, is a testament to Hamilton's commitment to quality and the art of watchmaking. It embodies American vintage style fused with the innovative precision and beauty of Swiss movements. The stainless steel case measures 40 mm in diameter and is topped with a scratch-resistant sapphire crystal, while the screwed case back is transparent - revealing the oscillating weight of the automatic movement.

The Dial
This timepiece features a round, grey dial with striking finishes. The open-heart display lets you admire the watch's movement, while the sunray finish creates beautifully shimmering light effects. Hour markers are rose gold-toned baton indices, except at 3, 6, 9, and 12 o'clock which are marked with Arabic numerals. The minutes are indicated by a black minute track. The hour, minute, and second hands are rose gold-toned and coated with a luminescent material.

The Movement
This timepiece houses a Swiss-made automatic movement. The Hamilton caliber H-10, featuring 25 jewels, is based on an ETA C07.111 and runs at an oscillation frequency of 21,600 vibrations per hour. It provides hours, minutes, and seconds functions with an 80-hour power reserve.

The Strap
This timepiece comes fitted with a brown leather strap, fastened with a silver-toned pin buckle. The lug width is 22 mm.

Water Resistance
This model offers water resistance to 5 atmospheres (50 m). It is designed to be as beautiful as it is resilient. You can keep it on in the shower, though the Ocarat team recommends setting it gently on the edge of the sink to preserve its brilliance and integrity over time. Swimming and scuba diving are not recommended with this watch, as exposure may result in damage and repair costs.
