ISO 6425 Pepsi diver · 1996–2019

Seiko SKX009

The SKX007's "Pepsi" sibling — same case, same 7S26, blue-and-red bezel insert. The most-modded diver in history in its most-collected colourway.

Seiko SKX009 with Pepsi bezel

Same diver, different colour

The SKX009 is mechanically identical to the SKX007 — same Seiko 7S26 caliber, same 42.5 mm case, same ISO 6425 dive certification. The difference is the red-and-blue ("Pepsi") bezel insert and a jubilee-style bracelet on the K2 variant.

The Pepsi reference was Seiko's acknowledgement of the GMT-Master's iconic colour story — the SKX009 brought a dive-bezel version of that look down to a sub-$300 price point, and made it accessible to a generation of mechanical-watch enthusiasts.

Inside the Seiko SKX009

Like the SKX007, no hacking, no hand-winding. The 7S26 just turns.
