Experience the craft of Blancpain in the Fifty Fathoms (ref. 5100-1130-B52A), a refined timepiece that blends thoughtful design with reliable performance. A study in proportion and durability: crafted in stainless steel and measuring 38 mm in diameter, with a thickness of 10.77 mm, defined by a round silhouette, paired with a rotating, 0-60 (dive) bezel. The caseback is open, and the crystal is sapphire, delivering water resistance to 30000 meters. The dial composition is deliberate and legible: a black tone, framed by mixed hour markers, and baton hands. Beneath the caseback lies dependable performance: the 1153 caliber. Released in a constrained run, appealing to focused collectors. Introduced in 2019. Comfort and balance define the wearing experience, making it an easy daily companion. Subtle transitions between textures elevate the overall impression. For buyers researching specifications and real-world impressions, this reference stands out for coherent design, dependable mechanics, and lasting relevance within modern horology.
