Lumed Glass SKX007 & SRPD Bezel Inserts for Seiko Mod Builds
Every insert here is flat glass, 38mm outside and 31.7mm inside, made for the Seiko SKX007 and SRPD. Almost all also list the SKX009 and SKX011. The scale is printed in lume, so after dark the markings glow, and on many of them the whole track comes back, not just the pip.
Choose a Scale
- Dive track: the 60-minute scale, in SKX style with numerals at each ten, or PO style, graduated at every minute across the first fifteen. In black, blue, green, white, and two-tone Pepsi, Coke, black and white, dark blue and gray, and orange and gray.
- Dual time: a 12-hour scale, numerals 1 to 11 with a marker between each hour, in Pepsi, Coke, and blue and white. Turn the bezel by the hour difference, and the hour hand reads a second time zone off the bezel, in 12-hour time.
- GMT: a 24-hour scale, read by a GMT hand, so it belongs on an NH34 GMT or Seiko 5 GMT (SSK) build. In black, black and green, black and red, and black and gray.
- Arithmetic blocks: no timing scale, just alternating blocks carrying multiply, plus, minus and divide signs, in dark blue, orange or black.
Green or Blue Lume
Most inserts glow green. The GMT inserts let you choose C3 green or BGW9 blue lume when you order, and the SKX style black comes in green or in BGW9 blue, each sold as its own insert.
Before You Order
Each insert comes with one piece of 3M adhesive. Check the measurements against your bezel before ordering: once installed, the insert can't be removed without damaging the print, and it can be damaged by prolonged soaking in water. We don't refund or replace an insert damaged after installation.
Crystals, Bezels & Other Inserts
We recommend the SKX007/SRPD Flat Sapphire – For Flat Insert with almost every insert here, in the SKX007 & SRPD sapphire crystals. Fit your insert to an SKX007 & SRPD rotating bezel, or an SSK bezel for a Seiko 5 GMT. For other materials, see the SKX007 ceramic, aluminum and stainless bezel inserts.
Frequently Asked Questions
Are these inserts sapphire?
No. Every insert here is flat glass, with the scale printed in lume.
Which watches do they fit?
Every insert here is made for the Seiko SKX007 and SRPD, at 38mm outside and 31.7mm inside. Almost all also fit the SKX009 and SKX011, and most fit rotating bezels of the same measurement. The SKX013 has glass inserts of its own, sized for that watch.
Can I remove the insert once it's fitted?
No. Once installed, the insert can't be removed without damaging the print, so check the measurements against your bezel first. We don't refund or replace an insert damaged after installation.
Can I choose the lume colour?
On the GMT inserts, yes: C3 green or BGW9 blue. The SKX style black comes in either colour as separate inserts, and each of the others names its lume on its own page.
