Bezel Inserts for SKX007, SKX013, SRP Turtle & SNZF17 Seiko Mods

Bezel Inserts for SKX007, SKX013 & SRP Turtle Seiko Mod Builds

Every insert here is made for one watch, and its size shows it: the SKX007 and SRPD inserts are 37.8–38mm across, the SKX013 inserts 33.6–33.7mm, and the SRP Turtle inserts 39–39.1mm. Choose your watch first, then the material, then the scale.

Choose a Material

• Ceramic: far harder than the steel bezel it sits in, so it resists everyday scratches, and its colour doesn't fade in sunlight. Flat or slope.
• Lumed glass: flat glass with the scale printed in lume. Once fitted it can't be removed without damaging the print, and we don't refund or replace a glass insert damaged after installation.
• Aluminum: fits under the original SKX007 Hardlex or SRP Turtle Re-issue crystal.
• Stainless steel: a steel face, brushed on most, and on many the markings are cut into the metal rather than printed.

Choose a Scale

• Dive scale: the 60-minute track, in Sub, SKX, Vintage Sub, PO and more. Turn the bezel until the triangle sits over the minute hand, and it reads the minutes that have passed.
• Dual time: a 12-hour scale. Turn it by the hour difference, and the hour hand reads a second time zone 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.

Frequently Asked Questions

Will an SKX007 insert fit my SKX013 or SRP Turtle?

No. The SKX007 and SRPD inserts are 37.8–38mm across, the SKX013 inserts 33.6–33.7mm and the SRP Turtle inserts 39–39.1mm, so each watch takes its own. Check each insert's inner and outer measurements against your bezel before ordering.

Which material should I choose?

Ceramic resists everyday scratches and its colour doesn't fade in sunlight. Lumed glass glows after dark, and once fitted it can't be removed without damaging the print. Aluminum fits under the original SKX007 or Turtle crystal. Stainless steel is a steel face, brushed on most, with the markings cut into the metal on many.

What's the difference between flat and slope?

The profile of the insert's face. It decides which crystal sits flush with it, so most inserts name the crystals to pair with them.

Will an SSK bezel take these inserts?

The SSK rotating bezels take all of our SKX007 and SRPD bezel inserts.
