SPB143 Mod — the 62MAS look as a Seiko mod | MedoMods
The SPB143 is Seiko's modern reinterpretation of the first Prospex diver from 1965 (62MAS): a compact 40.5 mm, sapphire crystal and a clean vintage-diver look. The SPB143 itself is a cherished watch and not a typical donor — but the sought-after 62MAS look can be built as a mod on a more affordable base with the right case and sandwich dial.
