Of late the Sinn U1 reps were coming with green markers and had horrid grainy lume. Sure enough, received a U1 dial and it had blotches of light lime green markers and the lume was appaling compared to the rep Sinn U2. As a favour to my friend, whipped up the trusty horostick and lumed to save his poor dial. Looks much better imho than when i received it... Not sure what happened to this rep that used to be quite brilliant otb... Pics of lume before touching up are enclosed.

Hopefully, this is just a batch problem with the Sinn U1s and the quality of rep lume will improve.. otherwise it'll be such a waste of an excellent rep for a nice diver's watch.
