I picked up a vintage Rolex recently that came with an older rivet bracelet. When the watch arrived, I thought the bracelet had a female bracelet clasp and a few female links. The seller of the watch told me that he believes it is original and upon researching early rivet bracelets, I think the seller might be right. From what I’ve read and seen online, there are rivet bracelets that have clasps as small as 13mm. I’ve found examples for sale that have similarly tapering designs and small clasps, for example this 7205:

I was hoping someone could shed some light on the authenticity of the bracelet and if it’s also a 7205.

Thanks in advance!

 

With that small clasp I think it could be a 7204. edit: Belay that -- we need dimensions of end-links.

The overall detail in the your photos matches well to my slightly later 6636.
As it is totally unbalanced in the number and progression in size of the links on each side I think it's had some amateur attention

Did you find this Hodinkee article https://www.hodinkee.com/articles/rolex-oyster-bracelet-historical-perspectives ?

 

I came across that article - forgot to mention that the end links are 19mm... which made me think it’s a 7205 like the one in the link I posted.

 

Looks authentic, and very likely 7205. I'd send it off to LA WatchWorks and have them (a) tighten it up and (b) sort out the progression so that the one tiny link doesn't look so lonely. They usually have a reasonable supply of rivet links on hand.

 

The 19mm end link bracelets would have the smaller clasp, as noted above. Normally they came with 7 and 5 links on either side of the clasp. It appears you are missing one link, that would go in the spot where you see the large width difference on the side that has 4 links. Can be made to look better, but would leave it to a pro!

 

The 19mm rivet and folded link oysters have that unbalanced look of the mini clasp which makes me prefer the 78350. The end links on the 19mm rivet brackets are rather ill fitting as well.

 

I too think its a 7205. Those 61 end links were commonly used on Tudor watches
