Seiko SRPE Mod Parts, by Type
Upgrade one part of your Seiko 5 SRPE, or build a new watch around a replacement case. Each part names the SRPE references it fits, so check yours against it before ordering. The sapphire crystals and glass gasket also fit SRPG and SRPH references.
- Cases: 38mm across without the crown, in 316L stainless steel with a screw-down crown. Choose the steel replacement case with its crown at 3.8 o'clock, or a 3 o'clock crown case in steel, gold, rose gold or black. Each is sold with no case back, a stainless steel one or a sapphire one (brushed black instead of steel on the black case). Every case takes an SKX013 crown, not an SRPE one.
- Bezels: fluted, pilot, ANA, SRPE style and GMT designs in 316L stainless steel, each with the glass and bezel gaskets pre-installed.
- Chapter rings: 27.5mm inner and 32.7mm outer, in polished, brushed and laser-engraved styles, black with a white marker, and with GMT markers.
- Sapphire crystals: a double dome with blue or clear anti-reflective coating, and a flat crystal with clear anti-reflective coating and the same specs as the original hardlex. Each comes with or without a glass gasket.
- Crowns: an engraved "S" in polished silver, gold, rose gold or sandblasted black, with knurled versions for a better grip. Each comes with a free stem for the NH movement.
- Bracelets & straps: Jubilee, Oyster and President bracelets in 316L stainless steel, tapering from 20mm to 16mm, and FKM rubber straps for 20mm lugs.
- Gaskets: bezel, glass and case cover gaskets, in packs of one, two or three.
Building an SRPE GMT
The SRPE GMT bezels and GMT chapter rings are made for building a 38mm GMT watch. If you're fitting an NH34 movement, use the SRPE double dome sapphire crystal. The NH34 GMT movement and GMT hands are in the SRPE GMT modification parts, and you can browse dials and hands to finish the watch.
Frequently Asked Questions
Which watches are these parts for?
Every part here is made for the Seiko 5 SRPE, and each names the SRPE references it fits. The sapphire crystals and glass gasket also fit SRPG and SRPH references, and the case cover gasket also fits the SNZF17 and the SRPD. None lists the SKX007, SKX013 or SRP Turtle, which have parts of their own, sized for those watches.
Will an SRPE crown fit the replacement cases?
No. The replacement cases take an SKX013 crown, and neither an original nor a replacement SRPE crown fits them. The SRPE crowns here are made for the Seiko 5 SRPE watch itself. For a replacement case, choose from the SKX013 crowns.
Can I build an SRPE GMT?
The SRPE GMT bezels and GMT chapter rings here are made for a 38mm GMT build. If you're fitting an NH34 movement, use the SRPE double dome sapphire crystal. You'll find the NH34 GMT movement and GMT hands in the SRPE GMT modification parts collection.
