SRPE Replacement Cases for Seiko Mod Builds
Every case here takes the Seiko 5 SRPE's original and replacement parts, except the crown. Each is 38mm across without the crown, 316L stainless steel, with a screw-down crown, 20mm lugs, drilled lug holes and 100m water resistance. Each takes an SKX013 crown; an original or replacement SRPE crown won't fit.
Choose a Crown Position

Movements & Dials
The cases take the NH35 and NH38, and the NH34 GMT movement when fitted with the SRPE double dome sapphire crystal. Most state that they can only accommodate 28.5mm dials.
Crowns, Crystals & the Rest of an SRPE Build
Choose the crown from the SKX013 crowns, the crystal from the SRPE sapphire crystals, and finish with an SRPE bezel, chapter ring and bracelet. Every SRPE part is in Seiko SRPE mod parts.
