AHW Bolt Face Crown for Seiko Divers

In stock


- +
SKU: N/A Category:

Finally, an aftermarket crown worthy of the work being done in the custom/modding community. Internals have been engineered for strength and longevity. Dual seal design- both on the stem housing (stock location) and inside the crown body to seal against the case tube. Designed to accommodate stock Seiko gaskets during future service.

Fits most large Seiko automatic divers that are powered by the 7S/4R/6R family of movements. SKX007/9/11, SRP777, etc. Accepts threaded stems to convert 7S movements to hacking/handwinding.

Available either with or without stem, trimmed & cemented for SKX007 sized watches, or full length for DIY fitting.
