Inspired by the original Longines Ultra-Chron Diver of 1968, the new model and its new high-frequency calibre represent the first reinterpretation of what sets Longines apart – its status as a pioneer in the world of sports timing. The vintage inspired Ultra-Chron features a 43mm case holding a black dial. The stainless steel piece is rated for 300M water resistance. The watches screw down crown and sapphire crystal make it a durable wear that mixes vintage and modern seamlessly.
