The Broad Arrow Hand Overview 2990 2913 2914 2915

Yes the size seems exactly correct. It’s the flatness and lume that are the questions, although the flatness is very hard to judge from photographs alone and it might be the same as some known 2915 hands. I’ve been through the other bits and sadly no minute hand, sweep hand, or sub hands !

Hey
the hand you are showing is a service hand...I am 100% sure about that
I have seen at least 5 different versions by now.
Would be interesting to know what lume material was used. you said it is reacting on your Geiger counter - what does it say exactly?
Your hand might be from the 70s or younger..

Thanks for the reply 👍

In the background I was speaking with an OF friend who had to buy hands for his 2915, and he thought maybe it was a relumed original hand or perhaps a service hand. His suggestion was that it looked the same as one in the 2915 section of @Spacefruit speedmaster101 site (the left hand side one).


The comment there is "It is possible these are all more modern than 1959, but earlier than 1970’s. They are original Omega parts."

Circumstantial evidence (for the little it's worth) suggests it should be pretty old as everything else in the lot seems to be early (let's say pre-seventies, excluding the pusher cap and crown which I don't know). I can ask the seller if there is anyway to date his watch stuff.

Then regarding the lume. It was barely above background but did seem to have some signature. Certainly not radium though. If background was 0.15 then the hand pushed it to 0.18. I have a UV torch so I'll check the behaviour when I get home.

@Omegist So I got it under the UV and it behaves pretty much exactly the same as you’d expect from tritium. It’s very bright at the start and dims pretty significantly in the first few seconds, then it’s a slow decay in brightness down to nothing noticeable after a minute or so. I’ve got a sixties tritium LeCoultre Polaris dial and when charged side by side they behave in a very similar manner.
