Caseback info...

[automatico]

I saw a while back where a couple members were wondering if any replica casebacks would fit a genuine rolex 16000 etc case.

A caseback from a noob F520117 submariner has the exact same threads but the od is a bit bigger and will need to be cut down.

genuine 16000 cb threads...30.90mm

noob cb threads...30.92mm

Use 30.9 as a reference.

16000 cb od...32.4mm

noob cb od...35.5mm

You will only need to remove about 1.5mm of material to get it down to 32.4mm+/-.

16000 cb overall thickness inc threads...4.35mm

noob cb overall thickness inc threads...5.05mm

material thickness in the center of the 16000 cb = .8mm

material thickness in the center of the noob cb = 1.4mm

Anyone handy with a lathe can turn the noob cb od down to fit the DJ case and there is enough material in the noob cb to reduce the overall thickness a little if desired.
