Released in 2017, the Mk IV Vanguard had markedly improved build quality and darkness visibility. The first Mk IV models, which had 42mm cases, featured the SuperSandwich™ dial that's filled to the brim with Swiss Super-LumiNova, to achieve the best darkness visibility ever on a Gruppo Gamma timepiece.
Visually, the most prominent change from Mk III to Mk IV was the design of the numeric markers on the dial.
