I just realized that I have three grey 3-hander dials from GP. All Laureatos.
And I have comes to see how well GP does with dial colors …. especially grey.
Generation 5 of the Laureato my 38 mm. This model is discontinued now. Gunmetal grey is how I would describe it. 
Then I have my 42.6 mm Laureato Generation 4 called the Evo3. This one is quartz and rather rare. Ref 80188. Silca blue-grey dial color
And finally my Laureato 8010 generation 3 at 36 mm. Rose gold bezel and magnificent Metalem dial. Thin case at 7.9 mm. Anthracite grey is how I would describe it. 
As you can see, I like wearing different size watches watches.
All three have grey dials. And while not fifty, I do appreciate the shades of grey.
A nice alternative to more severe black dials and yet retaining a level of sobriety.
Hope you enjoy the pics. As always, do share questions/comments here.
