Seiko Pump Watch

Hello,

I have created here a replacement for the pump that tends to wither away.
This is my first upload, so expect things to be a but rough and ready with details :-)
No spares are available, so I made a 'dummy' replacement.
This is non-functional and is quite delicate, likely to be used once or twice before the locks will be too damaged for use.
It is however wearable once in place and by far the best solution for this watch.
Note you will have to remove the remains of the soft plastic from the large and small locking rings to then put the 3d printer replacements.
Please advise for any info you may need, as I say this is my first upload.
