Seiko 5 GMT Mod Parts for SSK001, SSK003 & SSK005 Builds
Start with the bezel. Every SSK rotating bezel here takes all of our SKX007/SRPD bezel inserts, so swapping the bezel opens up the whole insert range for your Seiko 5 GMT. Each bezel is 316L stainless steel, comes with the rotating bezel gasket installed and one piece of 3M adhesive, and fits the SSK001, SSK003 and SSK005.
SSK Bezels
Coin edge, MM style or Sub style, each in steel, gold or rose gold. Several also list the SSK017.
GMT Inserts
A 24-hour insert is read by the fourth hand, so on an SSK it shows home time. The GMT inserts here come in slope ceramic (Pepsi, Batman, Coke, Stealth, gold marker, and black and green), in flat ceramic (black and gray B. Wayne, and black and green), and in lumed flat glass. A Yacht Master insert is here too.
Which Crystal
The SSK bezel pages recommend these crystals:
- SKX007/SRPD Double Dome Sapphire Crystal for Slim Bezel: the double dome.
- SKX007/SRPD Flat Sapphire – For Flat Insert: a flat crystal that leaves no gap between the insert and the crystal.
- SKX007/SRPD Flat Sapphire Crystal: to replace the original crystal with sapphire.
Each insert also names the crystal to pair with it, so check the insert's page too.
Crowns, Bracelets & Straps
The SRPD/SSK crowns fit the SSK001, SSK003 and SSK005. The SRPD Oyster and Jubilee bracelets fit the Seiko 5 GMT SSK models, and FKM rubber straps for the SKX007 and SRPD round out the build.
Frequently Asked Questions

Yes, with an SSK rotating bezel. Each SSK bezel here takes all of our SKX007/SRPD bezel inserts and fits the SSK001, SSK003 and SSK005.
