Perrelet Class-T Chronograph 44mm A1069/B By combining modern innovations with a traditional aesthetic, Perrelet have created the Perret Class T Chrono watch collection. Every Perrelet Class-T watch is equipped with an automatic movement, a silent tribute to founder Abraham-Louis Perrelet’s invention in 1777 which cemented the brand’s passion and enthusiasm for horology within the industry. Housed within the 44mm stainless steel case, the P-271 automatic chronograph movement works hard to make the rose gold plated sub dials, hands and date feature tick fluently on the striking black dial that sits beneath the scratch resistant sapphire crystal glass. The Perrelet Class-T Chrono watch promises a power reserve of up to 42 hours and a water resistance of 50 metres while being secured on the wrist by a classic black calf leather strap with white stitch detailing and a stainless steel folding clasp.
