Hamilton Jazzmaster Open Heart: A Blend of Tradition and Modernity
The Hamilton Jazzmaster Open Heart collection represents a harmonious marriage of classic watchmaking principles and contemporary design. These timepieces offer a glimpse into the intricate mechanics within, appealing to both seasoned watch enthusiasts and those new to the world of automatic movements. The collection distinguishes itself from full skeleton watches by strategically revealing key components without sacrificing dial symmetry or legibility.
A Closer Gaze at the Design and Features
Available in 36mm, 40mm, and 42mm case sizes, the Jazzmaster Open Heart caters to a diverse range of wrist sizes and preferences. All models feature a stainless-steel case with a combination of brushed and polished surfaces, creating a refined aesthetic. The cases maintain a comfortable thickness of approximately 10mm to 11mm, ensuring wearability for everyday use. A sapphire crystal with anti-reflective coating protects the dial, and the watches offer a water resistance of 50 meters (165 feet), suitable for both formal and casual occasions.
The signature Open Heart aperture reveals the balance wheel and other moving parts, providing a captivating visual element. New dial variations incorporate smoky gradient finishes in colors such as silver, gold-toned, deep blue, turquoise, and brown, adding distinct personality to each model. Applied indices and faceted hands, coated with Super-LumiNova, ensure clear readability in low-light conditions.
The H-10 Automatic Movement
Powering the Jazzmaster Open Heart models is the Hamilton H-10 automatic movement. Based on the ETA C07.111 (itself derived from the ETA 2824), the H-10 operates at 21,600 vibrations per hour and boasts an impressive 80-hour power reserve. The inclusion of a Nivachron balance spring enhances the movement’s resistance to magnetic fields, temperature fluctuations, and shocks. An exhibition caseback allows for a view of the movement’s finishing, which is described as industrial yet honest.
Options for Straps and Bracelets
The Jazzmaster Open Heart is available with either a five-row stainless-steel bracelet featuring a folding clasp or on leather straps. Leather strap options range from patinated calfskin to clean white leather, allowing wearers to customize the watch to their individual style.
Availability and Pricing
The Jazzmaster Open Heart collection is a permanent part of Hamilton’s catalogue, with some references already available and others slated for release in May 2026. Pricing starts at CHF 920 for the 36mm model, even as the 40mm and 42mm versions begin at CHF 995 and reach up to CHF 1,075, depending on the chosen strap or bracelet. As of February 24, 2026, current pricing in Canadian dollars for the 42mm model is CA$1,480.00 Hamilton Watch.
Is the Hamilton Jazzmaster Open Heart a Good First Automatic Watch?
