Longines blue is more than a color choice; it is a shade closely tied to the brand's identity, and in 2018 it came to La Grande Classique. The La Grande Classique de Longines L4.908.4.95.2 pairs a blue sunray dial with a matching blue leather strap on a slim 36 mm steel case.

Launched in 1992, La Grande Classique is known for its thin, flowing silhouette, achieved in part by a patented construction in which the caseback also forms the strap attachments. That makes the watch hug the wrist in a way thicker designs can't. The blue sunray finish shifts from bright cobalt to deep navy as you move, giving an otherwise minimal dial plenty of life.

Unlike the quartz versions of the line, this reference runs on a self-winding Longines L591 caliber at 28,800 vph, with a transparent caseback to show it off. The tonal blue strap makes the whole watch feel tailored, and 36 mm is a sweet spot for both men and women who prefer a classic scale.
