Chaps,

I've drawn up the custom Seiko 6309 crown will send the production drawings out Sunday night hope to have the first protos made this week>>>

The custom crown will be totally compatible with the standard Seiko o-ring, the only difference being the knurl pattern, or grip design etc.

Looking good - have you thought about doing a longer version for John's TST? Would be popular round these parts I expect.

Yes I would love that also.
Big crowns make watchs look good.
Also a few different types of knurling.
For the TST it could use some longer ones for
a sure grip also. :sign0098:

Length - the standard crown is 3.4mm? .... Could you do the the 3.4 and 5.4 versions?

re

Ermm the original knurl is ROUGHLY 3mm wide, I've taken the OEM overall dimensions and had to guess the odd dimension for example the radius and chamfer etc.
