I think you are overthinking the lume color. If this was a watch I was interested in not for one second would the lume color deter me.

I own a 2541.80 with a new dial installed by Omega last year and the lume leans green in normal lighting. Just a bit. I also have a 2531.80 with a new dial installed by Omega last year--same thing.

It’s not the lume color. It’s the color of the marker in daylight.

Actually I couldn’t care less if it has lume or not, even less the color of it.

You should have made this clear in your earlier posts. The markers look white to me in some of those photos.

You cannot separate the color of the lume from the color of the marker. The lume used on these watches is emitting light in the green (and very slightly yellow) spectrum, so they generally appear somewhat green. Both 502 and I have hypothesized that this watch may only be appearing this green because of the camera used- let me re-iterate that this is a testable hypothesis- if you have a patient seller my next step would be to ask them to take some pictures with a completely different device or camera. That would rule out a camera issue. Either way, I'd bet it looks great in person.
Best of luck! I haven't looked at the photos extremely closely but at a glance it looks like a nice example.

Nono! I’m not concerned it’s fake. What I am trying to find out is that if maybe there were different batches of superluminova that made some look greener and other whiter. And if that is the case, if this specimen is one of the former.

I really want to buy it as everything else looks great and the price is ok.

But this one thing is bothering me.
Every Omega Seamaster from that era that I have ever handled has that greenish tinge to the lume. As others have said, you are overthinking it.

This.

The case looks good, nice and sharp. The lume is what it is. It’s the same for most luminova 2531’s.

very fair price

For the apparent condition and the presence of box and papers, I would agree. There's a bit of a premium in those things.

The only question I would have is how well it is running and when it was last serviced. If it is running well but the service history is unknown, I would probably take it to a boutique and have a water resistance test done and budget the cost of a service in the next 5 years or so.

A bit of encouragement for @OmegaBorder :

Erich, your watch looks stunning and that is what I want. But I see your markers way whiter, making the dial look beautiful, not at all like the seller’s 😭.

I understand what you are saying about the camera but he is probably using one of the phones you are all using and the rest of the pictures I see online are using. I mean how unique can his phone be?

Based upon the lens reflection in this image I think this is an iphone camera.

You might find these threads interesting:

I'm not a huge fan of AI overviews- they need double-checking- but Gemini says:


you can perform the same search and review the instances this has been observed, but it looks like a common issue discussed on a number of communities.



I know I have seen images much like the ones you posted on reddit, but I'd have to look through an aggregate of 2531 photos to find the ones I remember. In your photos, the pillow sometimes appears slightly green. Take a look at the pillow cover in the images from this post and compare them to the images in THIS POST. If that's the same pillow the difference in its appearance is tremendous. Also note that in this image, where you note the markers look the least amount green:



So does the pillow!

I strongly doubt this is coincidence- and I expect that something in the camera's settings caused the issues in the first series of photos.

I would politely express my concern with the lume to the seller, and ask him if he is using an iphone and see if he can send you different pictures--- if you still have concerns.

The color is the lume aging - totally normal for a 25 year old watch. What are they asking for it?
No it’s not that. These looked like this the day they were made. SL on Bonds can look green or white depending on the light. It’s normal. The only thing that degrades SL is moisture and I don’t see that here. Omega used subtly different shades of SL on the various SMP models. 2254s look whiter. Titanium models can look slightly yellow. It varies.

Thank you Padders! So what you are saying is that all SL on 2531s are the same correct? Meaning if I see the markers of this example greener than most others I see on the web/youtube/instagram it’s just the picture and lighting?

This is the only thing keeping me from buying the watch.

As noted above by others the apparent colour of the markers changes radically with lighting. In bright sunlight they can look white. In shade after you have been in bright sunlight they look green as they are glowing imperceptibly and in the reduced light your eye has the bandwidth to detect the shade. You don’t find white models and green models if that is your question. There will be variation as the dials were made for years but in general the Bond round indices are greener than some of the sword hand designs of the same era as different lume was used for each.

Just buy it. It’s a nice example and not a silly price. Were you to decide you don’t like it further down the road the penalty to move it on will be slight or non existent.

Many of us never move them on though, we end up with multiples.

Yes, and that is exactly my concern, that in the direct sunlight pictures he sent me the markers don’t appear white, they keep very green.

Here again two of said pics

Here is my 2351.80 with white/lime green markers from the late 90s/early 00s. I can grab other ones in different light conditions. Believe the markers are tritium, was right around the time of the changing over to Superluminova.

Easiest way to tell is a lume shot. Tritium-green, Superluminova-blue.

Used to know it once upon a time. Will need to get out the magnifier or grab a pic in sunlight to see it with the camera. Still dark here this morning atm and my eyes aren't as young as they were when I first bought it 25+years ago 😂
