Stainless case back for Datejust 6605?

I'm looking to replace the back of what I believe is a 1956 Rolex Datejust 6605. Does anyone here have a lead on this part? The back has someone's rather sentimental engraving, which I'd like to remove.

Michael Young can do this. If it is too deep his team can laser fill it and lap it back down to original, but it is quite possible it can just be re-lapped and the engraving goes away.

Post a photo.

I just hate welding stainless steel, regardless of whether it is by laser or by other means.

You always have internal stress as the weld zone will be stressed internally because of the shrinkage. This can contribute to stress corrosion and stress corrosion cracking, because of the crystal lattice structure of the steel has been disturbed due to stainless not being heat treatable.

If given a choice between a new one and welding, I would choose a new one. But that is just me!!!

Not sure if the date will be 100% correct for you, but happy to dig it out.

Very often you can just lathe it off.

And in the case of a 6605 caseback ...with a correct date code..and this one being original to the watch...

Next time you find a NEW 6605 caseback for 100.00 let me know.

I'm not a fan of laser welding stainless either.

Just options.

They will machine you a new caseback for a couple hundred bucks. Keep the original for when you pass the watch on. Grimes has made many parts for me, including a superb 6541 bezel.

I'd rather have this as a replacement than a "wrong" original back.

Best, H
