- The new Longines Heritage Collection, newly launched by Longines, features a watch that combines modern aesthetic concepts with vintage elements. The stainless steel case has been fully polished, giving it a more refined appearance. The movement uses the imported 2824 caliber, and the watch is designed in a standard dress watch size of 40mm. The strap is made of imported Italian leather and is available in green, brown, and blue. This is a classic and versatile men's watch that not only showcases the wearer's elegant taste but also exudes charisma in every gesture.
