Did Early 1960s Omega Seamaster Chronographs Have Tritium?

Hello all!

I have a 105.001-62 (circa 1962-63) Seamaster Chrono Cal. 321 which was very upsettingly redialed prior to my purchase.

I've been hunting for an original dial and one has come up however it has "T Swiss Made T" at the bottom...

Anyone have any pointers for what would be accurate for this model?

Tritium was introduced in 62 but some early dials did not have T’s on the dials. These generally appeared in 63.

What’s your serial number? The best bet would be to search here, Google etc for as many examples of your reference as you can, list the serials in order and try to locate a cut off point at which T’s started to appear on the dials.

That sounds like some heavy detective work haha

My serial is 20.521.XXX - I ordered an extract of the archives today but I also don't want to miss out on this sale as these dials seem to rarely come up....

serial-number-decoder.co.uk places my serial at 1963 but I know that might not be accurate.

Would you have any pointers?

Would you be able to link me to the ones you've found?

The one I'm looking at is listed for a 145.005..... hence my question. But I've been scouring eBay and haven't found any others!

I don’t know the answer if that’s what your asking.

You have the reference so it shouldn’t be too hard to search for examples on Google. If you don’t see any without T’s you know you’re likely good with a T dial.
If you see a mix of dials then you’ll need to cross reference by serial no to find an approximate changeover point and see where your serial fits.

This shouldn’t take too long.

Apologies, didn't mean to imply that you should find the answer for me or anything like that. I'm very new to the forum so I thought there might be some extra resources around the place that I might not know about.

Thank you for your input! I've done some googling and seems that there are some with and some without but I wonder whether the ones with the T's have had their dials replaced. The super sleuthing continues!

Hi,

this is the 105.001 I owned some days ago. (serial 19,8xxxxx)

No T's on the dial and the geiger counter says radium.
Cheers

Thanks for that! Very helpful.

Love that you tested it with a geiger counter!

From my research it seems that the earlier serials had the dauphine hands and the later ones more often have the other skinny kind (...no idea what the shape is called).

I wonder whether my (poorly done) redial was done to mimic the original dial which also doesn't have the T's....
