The Graham Swordfish Iris has an incredible iridescent case that truly makes it stand out, like an exotic fish or some faraway planet. WIth a calibre G1710, automatic bi-compax chronograph, 28’800 A/h (4 Hz) and Incabloc shock absorber with 34 jewels and a 48 hour power reserve, it’s an impressive timepiece that will hold your attention even if you can get over its gorgeous gleam.
