A bright expression of H. Moser and Cie.'s Pioneer line, this Pioneer Centre Seconds pairs the collection's sporty footing with the brand's distinctive Sunny Side Up yellow fumé dial. The 40mm stainless steel case keeps the look crisp and modern, with restrained proportions that let the color do the work. An automatic movement drives the time-only display with clean, everyday purpose. At 12.3mm thick, it wears with easy balance and a compact profile.
