Another advantage of the A4 (C4) sized watch box: a nice brochure nicely fits into the same container. The Angular Momentum watches are obviously shipped with a great Illum (the sports watches line) brochure containing great shots of the different Illum watches. Not really a coincidence that I opened the brochure showing my exact Illum II Diving Watch

PS Actual packaging of AM watches might vary. The outer boxes and the Illum II brochures might not be in the package for international mail for weight reasons
