Experience the craft of Corum in the Bubble (ref. L390/03694), a refined timepiece that blends thoughtful design with reliable performance. A study in proportion and durability: crafted in titanium and measuring 52 mm in diameter, with a thickness of 20.2 mm, defined by a round silhouette, protected by pvd coating. The caseback is open, and the crystal is sapphire, delivering water resistance to 10000 meters. The dial composition is deliberate and legible: a black tone, executed in brass, framed by stick / dot hour markers, and proprietary hands. Among collectors, it is nicknamed "Wire Face". Beneath the caseback lies dependable performance: the CO 390 caliber. Released in a constrained run, appealing to focused collectors. Introduced in 2018. 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.
