First Class Open Heart

First Class Open Heart

The First Class Open Heart collection revisits the brand’s grand classic, enhanced with contemporary accents, in tribute to traditional timepieces. The heart of the movement reigns supreme here. The elegant balance-wheel of the Manufacture P-391 caliber can be admired through the dial opening at 6 o’clock, providing a chance to admire its oscillations and thus enable an even more dynamic perception of time. The 42.50 mm steel cases with their distinctive fluted pattern, together with the grained and guilloché dials, reflect the aesthetic codes of the First Class family.
