Vintage 123B dial question.

I’ve owned the 123B 3-4 times since the early 2000s when it came out. Every time I sell it, I end up regretting it and finding another.

Now I’ve landed a keeper.

Every other example I’ve had, and most I’ve seen, had more or less pure white luminous markers/hands.

My latest one however, has a decidedly warm tone to the markers, not unlike what you’d see in aging tritium. I’ve seen the same coloration on perhaps one or two examples for sale online in the past.

Does anyone know if B&R might have used tritium on these older watches? There’s no T on the dial, which I thought was required by law. Could they have used it early on and skirted the rule? The watch was originally sold in Asia.

That model did not appear until 2001/2, at which point the industry had moved on from tritium almost entirely.

It'll be Luminova, but other compounds in the material will have aged in that time, giving it an off-white appearance.

Older Omega Seamasters from the early 2000s can also exhibit the same colour degradation. For example this one was only ever made with Luminova markers but has gone green over the years (originally they were a stark white):
