From Hublot, presenting the Big Bang (ref. 403.OM.0123.RX), a contemporary classic shaped by careful watchmaking know-how. The exterior is thoughtfully executed: measuring 45 mm in diameter, defined by a round silhouette. 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 mixed hour markers, and stick hands. At its heart beats a proven engine: the HUB5003 caliber. Produced in limited numbers, appealing to focused collectors. First released in 2015. 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.
