The Rettangolo Reserve de Marche features a hefty 29mm x 48mm platinum case, polished to a nice shine and complemented by a fixed, smooth bezel. The front of the case features grooves running down the sides which can be felt when you brush your fingers over the case. The watch is operated via a sizable crown located on the right side. Regarding case design, the Rettangolo's rectangular case is both simple yet intricate in design and, in some ways, resembles the Patek Philippe Gondolo 5200G, which we have offered here in the past.
