"Spreading" lume on Speedmasters?

I don't know myself. That's why I was hoping to get some feedback. I tend to agree with comments above that mine may be affected in some way whereas yours is just ageing. I don't know what would cause either sort though.

Luminova I imagine wouldn't degrade in the same way. Both yours and mine should be tritium... I'd imagine different batches would age differently.
Oddboy, you are quite right every batch of lume is going to be different, these mixes were not in the digital age but done by the "lume guy" who did it by weight and sometimes may not have been mixed enough. Binder , lume , colour, no wonder we get pretty and sometimes beautyful.

That's a normal degrading. It's often seen at Breitling dials (the lume of 806 is getting dark often maybe because of the non-waterproofness) and also on Heuer-dials.

I think the Op's query begs the bigger question of telling original vs relumed dial.
I have often seen posters comenting how a watch was relumed because there was some lume material transcending
the boundaries of the markers. Clearly this is not always true. As original markers degrade, they get messy, just like a relume can be messy.

I do not suggest it is impossible to spot a true relume by several methods (lumination, coloration etc), but I am convinced that in many cases it is near impossible to determine. And if nobody can tell, does it matter?

Over the next 50 years more speedies will be shedding their natural lume and relumes will necome more ubiquitous
and more accepted by the community. The lume jobs will get better and better and we will continue to love our vintage pieces.

Spreading lume, blooming lume, puffy lume - all subsets of the same thing, namely degrading and deteriorating lume. However, these euphemisms do seem to have gained traction. I wonder why?

Likely because saying "degrading lume" doesn't adequately describe the variations that can occur, and doing so makes it easier to communicate about specifics.

Must have been a bit crotchety when I wrote that. Call it whatever you feel accurately describes its senescence 😉

I understand the implication being made - rather than "euphemism" I think "descriptor" is a better word for what is being done here. Your anti-bias bias is showing...😉

Too much spicy chinese food on a Friday evening, too much coffee on Saturday. I'll retire to a darkened room until my brain stops spinning.....😝

Yes, it's all degradation. So too is the change in colour to those orangey brown hues we all love on vintage speedies.

The point of the question is more about what is original vs "adjusted" .
Also would whatever effects a dial so that it turns brown also effect some change in the colour and consistency of the lume. I noticed in Speedmaster101 William isn't all that keen on green lume

Just thinking aloud here @oddboy.) I wonder if Tritium or Radium are effected by the level of magnetism in the watch?

After reading your question I decided to look up an article in Worn and Wound. It doesn't really shed much light but it's a nice read anyway. (link below)
I wonder if the presence of Zinc Sulfide in the tritium mix or that it is "produced by irradiating lithium metal" (quote from Wikipedia) would mean it could be moved across the dial. A bit like the old magnet and iron filings on paper trick???
So in short could the lume migrate depending on the level of magnetism within the watch ?

I could be talking complete and utter bollocks but I thought it may be worth throwing it in the mix???😕

Purely from observation and with no other evidence, it seems to me that green lume comes from countries with a lot of humidity while the orange and yellows are from more arid and warmer climes.

I sincerely hope that yellow lumed speedies that move to green lume countries don’t go some funky shade of baby-poo...
