Introducing Hamilton Boulton (ref. H13519561), a contemporary classic shaped by careful watchmaking know-how. The exterior is thoughtfully executed: crafted in stainless steel and measuring 34.5 mm in diameter, defined by a tonneau silhouette. The caseback is closed, and the crystal is sapphire, delivering water resistance to 5000 meters. At a glance, the dial balances texture and clarity: a green tone with matte finish, framed by roman numerals hour markers, and alpha hands. At its heart beats a proven engine: the H-50 ND caliber. With considered ergonomics, it feels composed during extended wear. Brushed and polished elements play with light to emphasize crisp geometry. For buyers researching specifications and real-world impressions, this reference stands out for coherent design, dependable mechanics, and lasting relevance within modern horology.
