I considered a GV but didn't like the orange batons so went for the standard black dialled version instead. I'm glad i did, as the dial on mine ranges from deep black, through charcoal to chocolate depending on how the light hits it and i wouldn't have got that effect through the green glass.
I actually think these will become collectable in years to come, they've got everything going for them, perfect size, unique case, unique dials, unique second hand, unique case back and not sold in huge numbers.
