Correct crown (gewinde 1/100)

I plan to buy a crown for a vintage tank-style watch before sending it to the watchmaker.

For a stem diameter of 0.9 mm, what is the correct measurement for the crown (gewinde 1/100)?

Thank you for the help.

You may also need to factor in the case/stem tube dimensions.

There are many generic crowns available on Boley.de

Also from Cousins in the UK.

PS: Your watchmaker should be able to determine a suitable crown and also source the part.
