With a handset that feels like a blend of Omega https://www.iworologi.com/ and Seiko https://www.iworologi.com/Collezione/aquatimer/ Monster, legibility is excellent and both the white and the black dial versions have additional contrast provided by opposing tones for the hands and markers (white on black or black on white). My preference is definitely with the silver/white dial as it https://www.crworologi.co/Collezione/tank/ gives a tuxedo effect with the black dial surround, and I like the red text for S617 (which is a reference to a French submarine, Le Temeraire).
