What is Longines' history? Longines was founded in 1832 in Saint-Imier, Switzerland, making it one of the oldest continuously-operating Swiss watch brands. The winged hourglass logo, registered in 1889, is one of the oldest unchanged trademarks in the world.
What movement is inside? A Longines Swiss automatic movement — self-winding, mechanical, and built for daily-wear precision. No battery required as long as you wear it regularly.
Does the 43mm size wear well day-to-day? Yes — at 43mm this sits in the modern sport-watch sweet spot, comfortable on average to larger wrists with strong wrist presence.
