I am planning an SKX Mod or Build. I want to use either a 4R36 or a 6R15 movement. Leaning toward the 6R15 at the moment.
I am aware that the 4R36 is a Day/Date and the 6R15 is Date only. Is there a way to add a Day wheel to the 6R15?
I plan on purchasing a SARB059 Alpinist Signed Crown with stem. Will there be any issues using this crown in a 6R15/NE15 movement?
Also is there a difference between the 6R15 and the 6R15D, or any model revisions in between?
