SKX007 & SRPD Ceramic Bezel Inserts for Seiko Mod Builds
Every insert here is ceramic, made for the Seiko SKX007 and SRPD, and most also list the SKX009 and SKX011. Ceramic is far harder than the steel bezel it sits in, so it resists the everyday scratches a bezel takes, and its colour is part of the material, so it doesn't fade in sunlight.
Flat or Slope
Choose the profile first, because it decides the crystal. Both are listed at 38mm outside and 31.8mm inside.
- Flat: we most often recommend the SKX007/SRPD Flat Sapphire – For Flat Insert.
- Slope: we most often recommend the SKX007/SRPD Double Sapphire Crystal for Slope Insert.
Each insert names its own recommended crystal, so check it before you order.
Choose a Scale
- Dive scale: the 60-minute track, in Sub, Vintage Sub, Mil Sub, SKX, PO and U1 style. Turn the bezel until the triangle sits over the minute hand, and the scale reads the minutes that have passed.
- Dual time: a 12-hour scale, numerals 1 to 11 with a marker between each hour. Turn the bezel by the hour difference, and the hour hand reads a second time zone off the bezel, in 12-hour time. In Pepsi, Coke, Batman, Root Beer and more.
- GMT: a 24-hour scale, read by a GMT hand, so it belongs on an NH34 GMT or Seiko 5 GMT (SSK) build. In Pepsi, Coke, Batman, Stealth and more.
- Yacht Master, count down timer and sterile: the Yacht Master style, a count down timer scale, or no markings at all.
Finishes & Lume
Polished or sandblasted, in black, dark blue, green, white, red, yellow and more, with gold, rose gold or tone-on-tone stealth markings. Some inserts are lumed, including C3 green and BGW9 blue, and on a few the whole scale glows.
Bezels, Crystals & Other Inserts
Fit your insert to an SKX007 & SRPD rotating bezel, or an SSK bezel for a Seiko 5 GMT, and find its crystal in the SKX007 & SRPD sapphire crystals. For other materials, see the SKX007 aluminum, lumed glass and stainless bezel inserts. For an SKX013 or a Turtle, see the SKX013 and SRP Turtle ceramic inserts.
Frequently Asked Questions
Will an SKX007 ceramic insert fit my SRPD?
Yes. Every insert here is made for the SKX007 and SRPD, and most also list the SKX009 and SKX011.
Flat or slope: which do I need?
Either fits the bezel; the profile decides the crystal. For a flat insert we most often recommend the SKX007/SRPD Flat Sapphire – For Flat Insert, and for a slope insert the SKX007/SRPD Double Sapphire Crystal for Slope Insert. Each insert names its own recommended crystal.
What's the difference between dual time and GMT?
A dual time insert is a 12-hour scale: turn it by the hour difference and the hour hand reads a second time zone in 12-hour time. A GMT insert is a 24-hour scale read by a GMT hand, so it belongs on an NH34 GMT or Seiko 5 GMT (SSK) build.
Are ceramic bezel inserts scratch-resistant?
Yes. Ceramic is far harder than the steel bezel around it, so it resists everyday scratches, and its colour is part of the material, so it doesn't fade in sunlight.
