Later 90s t swiss t

Do some later 90s t swiss t subs have superluminova instead of tritium?

I thought I read that somewhere. I want to pick one up with real tritium, so I'm not sure if I should be leery of late 90s subs like '98-ish.

I was checking out this one on the 'bay:

Tritium was used until 97/98.

The ebay watch has a dial marked for tritium. It is also has a U serial number - circa 1997.

I've seen U serial numbers marked tritium that glow like luminova. I would check with the seller and see if the dial still glows very bright which would indicate that it is luminova.

Wouldn’t they be “t swiss made t” ?

Yes, this happened to some of the dials during the cross-over period, although it would be luminova, not superluminova. Rolex didn't start using superluminova until 2000.

What does the U serial number mean? Does it just start with a U or something?

[swish77]

Yes, it starts with a U.
