Stainless Steel Screwdown Locking Crown & Case Tube – Tap 0.9mm – Watch Modification

Building or modding a watch?

This is a stainless steel screwdown locking crown with a matching case tube.

Tap size is 0.9mm.

Silver finish, unbranded.

The crown screws down tight, so your watch stays water resistant.

New without tags—might not be in the original package, but it's unused.

If you're putting together a custom diver or just need to replace a busted crown, this is the part.

Check your tap size before ordering.

Solid stainless, does the job.
