Stainless Steel Bezel Inserts for Seiko Mod
Find the right steel bezel insert for your Seiko mod build at Watch&Style. This page carries the two full-size dive platforms — 37.8mm outside by 31.8mm inside for the SKX007, SKX009, SKX011 and SRPD, and 39mm by 32.7mm for the SRP Turtle Re-issue — while the mid-size SKX013 takes a third size of its own, 33.7mm by 27.4mm, in its own collection below. None of the three is interchangeable, so the quickest way through is to start from the watch on the bench rather than from the design you want.
Insert Styles & Designs
Yacht Master is the largest family, with raised numerals at each ten and a baton at each five. Sub Style covers the classic sixty-minute dive track in plain steel, with a red 12, and in a red Vintage Sub. Dual Time and Explorer designs replace the dive track with a twelve-hour scale for a more formal face, and the SRP Turtle side adds its own SRP Red and Sub Style black and red inserts. Across every design the markings are part of the metal rather than printed onto it — cut into the steel on most, standing proud of a brushed field on the Yacht Masters — so the insert stays one colour and one material throughout.
Sizes & Platforms
Steel inserts are sized per platform and do not cross over — the SKX007, SKX009, SKX011 and SRPD share one size, and the SRP Turtle Re-issue is a size up. Finishes run black, silver, gun metal, gold, rose gold and Chameleon, and each insert swaps straight into the rotating bezel already on the watch.
Building Around Your Insert
Go straight to your platform: SKX007 and SRPD stainless bezel inserts, SRP Turtle stainless bezel inserts, or SKX013 stainless bezel inserts. To compare materials before you commit, see ceramic bezel inserts, aluminum bezel inserts and sapphire bezel inserts, or browse the full bezel insert collection. The bezel your insert drops into is in rotating bezels.
Frequently Asked Questions
Which size do I need?
Match it to the case, not to the design. SKX007, SKX009, SKX011 and SRPD builds take the 37.8mm outer by 31.8mm inner insert; the SRP Turtle Re-issue takes 39mm by 32.7mm. If you are not certain which you own, measure the insert currently in your bezel across its widest point — the two sizes are more than a millimetre apart, so the measurement settles it.
Is there a stainless insert for the SKX013?
Yes, but it is a third size — 33.7mm outer by 27.4mm inner — so it lives in its own collection rather than on this page. See SKX013 stainless bezel inserts for the Sub Style, SKX Style and Dual Time designs made for it.
Can I fit one to the bezel I already own?
Yes — that is what these are for. A steel insert swaps into the rotating bezel already on the watch, and nothing under the crystal is disturbed, so a worn or faded insert can be changed without touching the movement, the dial or the hands. Check the package note on the product page for what is supplied with the one you choose.
