Master Collection Chronograph
Ref.: L2.859.4.92.6
The Longines Master Chronograph hits the sweet spot between sharp and chill. With a killer 44mm stainless steel case and a dial in sunray blue that’s cooler than your favorite denim, it’s got style locked down. Inside ticks an automatic column-wheel chronograph, good for 54 hours. Impressive without bragging. And yes, there’s a see-through case-back because craftsmanship deserves an audience. Perfect for dressing up or dialing down.
