I think JLC does care about its customers.
On this particular problem of lume on the dial, they could propose a solution or at least communicate with the customers that would want to know whether or not something can be done. I suppose it could be easy if the customers would register their tribute to polaris on the JLC website, then JLC coudl communicate directly. would this provide a solution in a form of a recall of the watches to change the dials: I doubt it, but surely this would make watchfans appreciate the brand more.
I also think that a good old fashioned letter written to the "grande maison" has a weight bigger than just a sheet of paper.
But do JLC peole franticly read every post of every dedicated forum where their brand is mentioned? I hope not.
anyway, I wish I had a tribute to Polaris on my wrist when I see all the nice pictures of wristshots of the beast.
