Donor models for Seiko mods
The donor watch determines the case, movement and mod possibilities. Here are the key bases compared.
Seiko SKX007
The SKX007 is the icon of donor watches: affordable, rugged and backed by the largest aftermarket parts ecosystem in existence. Almost any look can be built from it — from Submariner style to a fully custom design.

The SKX009 shares its case and movement with the SKX007 — the difference is the blue-red Pepsi bezel and dark blue dial. As a donor it behaves identically and is perfect for blue or Pepsi builds.

If the 42 mm SKX007 is too big, the SKX013 is the answer: same tech, but a compact 38 mm case. The aftermarket is smaller, but it is ideal for clean, classically proportioned mods.

After the SKX was discontinued, the SRPD (5KX) line became the new standard donor. It is available brand new, uses the more modern NH36 movement with day-date and is largely mod-compatible with SKX parts.
