For anyone considering a Seiko SKX hacking/handwinding upgrade, please see the tips I learned from my latest adventure. Most of these will not be news to experienced folks, but newbies like myself may appreciate them. A few links are provided for additional info, but most parts can be sourced from a variety of dealers.
1. A 6r15 hacking/handwinding movement will fit in a Seiko SKX case. In fact, for a short time, Seiko made several SARB models using the SKX case and 6r15 movement with a unique bezel/dial/hands/chapter ring. Link: http://www.watchsleuth.com/seikosarf...h/?MOD=SARB061
2. You can’t buy a new Seiko-branded 6r15 movement online from a dealer, but Seiko makes the movement available under its unbranded Hattori line as the NE15 (not the NH15) Link: Hattori / SII NE Series Japanese Movement, -- NE15: Star Time Supply
3. A new movement will not come with the correct dial-holding spacer, but the spacer used to hold the 7S26 movement will fit perfectly. The part number is 4408171. Note, you will need to remove the date wheel to properly fit the spacer. Follow the steps used for removing the spacer from the 7s26 movement used in the SKX, and you should be fine.

4. The signed “S” crown/stem for a SARB061 will fit both the 6r15/NH15 and the SKX case. The part number is 1E70D1SNSO. Link: https://forums.watchuseek.com/f21/sar...1089291-2.html
5. If you replace a stock SKX crystal, you can reuse the crystal gasket that came with the watch. If you are building a watch from scratch, you will need to buy a proper gasket because aftermarket crystals do not come with gaskets. The part is 8660 0630.
