I have noticed some vintage watch guys on social media with 1675s and a crystal with no cyclops. I'm guessing that isn't original but I love the look. Crystal looks doomed? Can someone please provide me the details?

Note, I own a matte 16750 but I assume the non-cyclops crystal would fit my watch?

Cheers!

stmoore · 27 June 2020, 11:23 AM

T38, yes it will fit.

Not issued on the watch, but will fit. Could have been a service option.

BigBlue1 · 27 June 2020, 11:58 AM

Open your wallet though.

Hi,
Rolex manufactured the 1675 from 1960 to 1978/79, it has always been release with the "Cyclope Dial",part number Cyclope 116, but they have always had available as service part in the service parts catalogs the "Tropic 38" without lense. The tropic 38 remained available in the parts catalog for the 16750 as well.

So it is considered completely genuine.

Was the 1680 also available with the Non-Cyclops crystal (T19)?

I am not sure about Submariners, as I never been a big fan of it, I never dig too much.
However from the part catalog I have in my notes, it seems not available for 1680.

greatgoo · 27 June 2020, 07:49 PM

Very informative. Thanks everyone! I'll try to seek out an original T38. Is there a good source for am aftermarket T38?

No joke. Your posts, along with a few others I follow on IG prompted this thread.

cwilson13 · 27 June 2020, 10:34 PM

I just put a T38 on my 1675.

athom · 27 June 2020, 11:34 PM

Not according to the Official Rolex Part Catalog. They are different.

Below is a link for the Rolex crystal numbers from their R. 20 catalogue. It identifies the various factory crystals to include the Tropic 38 which is identified as a replacement crystal. The Tropic 38 can be found on 202-1.

Yes, it always been in the part catalog from 1960 available for 1675 and later for 16750 as service part.
I am not sure, as I am not familiar, but I think the same part number was available also for some Tudors.

What you really need is a domed T116.
The early ones had a wonderful smooth bevel around the edge - so it was a dome with the cyclops!

They're different. Also, an SD/Sub super-dome on a GMT would look a little silly, IMHO.

I'm a purist. I'd much prefer my GMT with a cyclops, the way they came from the Rolex factory.

Springers pages above provide the best answers.

T38 for 1675s.
T39 for 1665s.

The T39s are much different than the T38s and have a much larger dome.

This is my 1665.
