Experience the craft of Hublot in the Spirit of Big Bang (ref. 665.NX.1170.LR.1604), a contemporary classic shaped by careful watchmaking know-how. The exterior is thoughtfully executed: measuring 39 mm in diameter, defined by a tonneau silhouette, paired with a gem-set bezel. The caseback is open, and the crystal is sapphire, delivering water resistance to 10000 meters. At a glance, the dial balances texture and clarity: a black tone, framed by stick / dot hour markers, and stick hands. At its heart beats a proven engine: the HUB1710 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.
