Atelier de Chronométrie Introduces the AdC#88 in steel. Oversized and steel like the best of the 1940s. Barcelona-based independent watchmaker Atelier de Chronométrie (AdC) sticks to a simple but compelling formula: pre-war style wristwatches powered by drastically refined 1950s Omega movements. Coming almost exactly a year after the introduction of the AdC#4 with a cloisonné dial, the new AdC #88 is exactly that, in a slim, stainless steel case – a first for the brand. The steel case is 37mm in diameter, slightly larger than AdC’s earlier watches. It has a wide, flat bezel, and slightly thicker lugs, giving it a marginally more sporty look that’s reminiscent of the Patek Philippe ref. 570 in steel, a rare and valuable oversized Calatrava of the 1940s.
