Verifying Authenticity of Jubilee Bracelet??

[littlegino]

I recently purchased a used "genuine" Rolex Jubilee two tone (SS and 14k) for my DateJust as my original two tone jubilee has multiple links that are cracking and I didn't feel like having it worked on yet. This new (to me) band I purchased has a Gold crown on the buckle, as opposed to the stamping that my original band has. For reference I have attached a couple pictures of the new (to me) band in question:






I am not an expert, which is why I am posting here, but these early Jubilee bands have been hard for me to try to authenticate myself as they have no serialized or model markings on the bands.

For comparison, I have found some similar bands like this online that purport to be genuine, however, I can't find much information about this specific jubilee band, since the Gold crown on the buckle makes it pretty unique and easy to spot. The listings I did find online that match the new (to me) band in question have various dates attached to them (whether 50's, 60's, or early 70's) but I can't get a consistent answer. Most of the jubilee bands I see online are "newer' and appear to be from the 80's. My original band was older than this, however, I can't tell if this new (to me) band is older than my original! Not that it matters really.

Here are some links online of some similar bands to the one in question (it wont let me post the links so I separated the "www" and the ". net or . com"):

Anyone have any insight on if this is genuine Rolex or not? And/or any information about the history of this band (primarily the unique gold buckle)? I am wanting to know if i need to return this prior to installing it! The overall quality of the band looks excellent to me. Thanks!
