Originality of this 6605?

Can anyone help regarding the originality of this DJ 6605 for sale on Chrono24?
https://www.chrono24.com/rolex/datej...id14678487.htm
The hands appear ok to me, but I'm not sure if the dial is a later dial. The watch is from 1961 and all the DJ's I have seen from this time have a "Swiss" radium dial. This one is marked "-T Swiss T-". Any feedback would be much appreciated.

I think your right it should be a Swiss only dial. It would have been nice of them to provide the serial # I own a 1,003 that is a underline dial " transitional " period and a 823, and a 880, both of them are Swiss only

Hope this helps Chris

I would assume it’s a later dial.

What do the dashed lines mean,
-T Swiss T- ?

In the 70's, the gold industry wanted to tout gold products, so watches started marking those dials with gold indices with a sigma mark that looks a little bit like a small o.

Gold index dials of that era were marked oT Swiss To, and steel market dials were marked -T Swiss T-, so there was no confusion.

Hi Larry, that is very interesting information. I knew of the Sigma dials from reading on this forum, but didn't know anything about the dashes. This is a gold watch from ~1961, so clearly the dial is wrong. It is not only a later dial from the '70's, but also originally for a SS watch. Is that a correct interpretation?

I have seen many SS watches with the Sigma dial (small o). Are these all wearing incorrect dials originally made for gold watches?

Lastly, I am currently looking at a very nice yellow gold OP date from ~1978. The watch has a sigma dial (small 0), but my understanding is that these sigma dials were only used for a few years in the early '70's. Is there any way this is an original dial on a watch from 1978?

The sigma refers to the indices material, not the watch case.

Does this mean the Gold 6605 has a dial with SS markers?

Is there any way this dial is original to the watch?

I'm also looking at at a 1978 Yellow Gold Oyster Perpetual Date Reference 1503, 5.2 mil serial with a sigma dial. This seems late for a sigma dial. Is there any way a sigma dial is correct and original to the watch?

I had a 5.0 & 5.4 serial with Sigma dial. That dial is not original to the watch in OP.

You often see the -T SWISS T- on 1963/64 Rolex watches. I’ve mostly seen it on Daytonas (6239/6240) but I would still keep it in that era. Not in the 70’s.

I wouldn’t be too bothered about this on a Datejust. What is the serial of the watch?

The Oyster Perpetual 1503 is a 5.2 serial number, which dates it to ~1978. I thought that was a bit late for a sigma dial, but it sounds like it is OK. Thanks Rootbeer7.

Why do you think the dial in my original post is not original to the watch? I know most from that era have a Swiss dial, but it seems to be close to the time of transition to tritium.

Hi Per, the Rolex Datejust in question from my original post is a 1961. Thanks for your feedback and pic of the Daytona (beauty). I still don't know it the dial could be original to the gold DJ.....there are conflicting opinions here. That is the purpose of the forum as I know there are no hard rules with Rolex.

The serial could be later than 1961. Lots of serial lists around so that is why I asked.

I haven't been able to get in touch with the seller so can't confirm the serial number. I am just going by the seller's ad. But assuming it is from 1961, does the dial appear correct and original to you?

It would make sense if the watch was from 63/64. If not it may be an early service part. Or just that the 61 case was assembled a couple of years later.

Find out the serial and search for similar watches. Then you will get a feeling for if it is touched or not. Personally I would not be bothered at all if a Datejust had a replaced dial. If that is the case.

Here’s a similar watch.

https://www.hqmilton.com/timepieces/...-18k-6605-2128

I would assume yours to also have a later dial. Knowing the serial would confirm it.

This has been answered I think above. The dial would appear a few years later. Get full serial number and it will be easier to answer.

Thanks for all the help. I cannot get in contact with the seller now and assume his is on lock down. I'll report back if/when I get the serial number. In the meantime, I believe this is likely a later dial as most have pointed out.
