|Hamilton Jazzmaster Open Heart Auto Silver - Leather Ref. H32705521
The Jazzmaster Open Heart Silver on Leather Ref. H32705521 sets forth where it is designed to be the perfect combination of certain savoir faire piece with modern technology. Measuring wittily at 42mm wide and 11.44mm in height, a combination of both brushed and polished stainless steel throughout the case mimics the typical sporty yet with beautiful contrast. Further, at 42mm, the Jazzmaster Open Heart bears 50m water resistant and wears exceptionally well and versatile from most of our wrists, both for men and women.
Ok, we are not done with the case built. Further, the case features a slight domed sapphire crystal accentuating above the thick polished bezel. Paired on the opposite side with a screw-in exhibition case back with essentials specifications engraved onto it. The lugs’s design reminds one of some horn-shape, enliven the overall uniqueness of the watch, rather than just running the mills of a typical round dress watch.
Semi-skeletonized dial to view the open work
Moving onto its semi-skeletonized dial, it essentially divided into two main sections where one bears applied Arabic and facet markers for the hours, all that flanging the semi-exposed inner dial that reveals the mechanical works at 12 to 4 o’clock and 7 to 8 o ‘clock segments.The dial is further paired with blue “flieger” sword-style hands, and all of them done with luminous for legibilty. There is no date display but nicely at the 9 o’clock position shows the “Hamilton Viewmatic” logo, resulting in the cleanliness of the dress watch while keeping things balanced overall. Strapping the Jazzmaster Open Heart to the wrist, one can conclude the contemporary built for a sense of classiness above all things.
The Jazzmaster Open Heart Silver on Leather Ref. H32705521 is powered by its Caliber H-10 which is a tweaked 25-jewel ETA C07.611 automatic movement. The main tweak has the power reserve pumped up to 80 hours while having the frequency of the balance slowed from 4Hz to 3Hz, or from 28,800 beats per hour to 21,600bph. Further, the mainspring got lengthened due to the reduction of the barrel arbor’s core. This allows a longer power reserve enhancing an automatic movement, with the lower beat-rate reminds one of an old school hand cranker found on vintage military watches. With all this said, Hamilton truly is the few that can produce such movement upgrade on a large scale and further being well priced.

Hamilton paired the Jazzmaster Open Heart Silver on Leather Ref. H32705521 with a 22mm sturdy burgundy brown leather strap that is suitable for all occasions and conditions.
