Hello,

this is my very first post.
I just purchased this beautiful Speedmaster Prof 105.012 -66.
Can someone spot whether it is a HF or CB?
Also do you see anything that looks off or replaced?

Thanks!

best

Does the seller have a picture of the inside of the case back?

No lug facets, so either an HF, or a refinished CB. Given the condition of the case, I couldn't rule out the latter. If you show good detailed photos of the case profile, there are some experts who can tell the difference just from the shape.

Since you say it's a 105.012-66, you should have a photo of the inside of the case-back.

Better hope it’s an HF.

As well as the well documented facets on the front of the lugs, CBS have larger facets on the underside of the lug tips (pic brow) so I’m confident this is a HF.


Wide facet on the underside of each lug tip (CB)

OP watch showing very narrow facet under each lug tip (HF)
