This elegant Longines tank really captures the refined Art-Deco style of the early 1940s with its dramatic triple-bar “wedding band” lugs. Inside beats Longines’ in-house caliber 9L, a finely finished 17-jewel rectangular movement produced for the brand’s U.S. market dress watches of the era.

The 9L has an indirectly-driven second hand pinion, which shares a bridge with the pallet fork. This is a highly unusual feature for sub-second designs, but allows for the use of a relatively large balance while maintaining the slim rectangular profile of the movement.
