L2.673.4.78.3

Overview

The Longines Master Collection Chronograph Calendar L2.673.4.78.3 "L26734783" is a 40mm men's automatic watch with a stainless steel case and a white analog dial protected by sapphire crystal. It uses a L678 caliber self-winding mechanical movement that can be manually wound and hacked (the second hand stops when the crown is pulled out). It ticks 8 times per second which gives the second hand a smoother movement than quartz watches which tick once per second. The watch should run for up to 46 hours when fully wound and will self-wind when moved.
