Are well complemented, and together as if I can stay warm at night by their light. In most cases wise to stop here, in this case the betterment of the pair is to be found with Zw Luminous "Phantom" to make them three. Do I need the missing one, the origin...
Yes it will be wise to make the set with the Phantom, but I won’t go further with the original L1 Lumen since the GL1 Moonphase Lumen is already better, imo.
I love the Grand Lange 1 Moonphase Lumen, and I also like the Grand Lange 1 Lumen (without the moonphase) a lot! Personally, I don't like the ZW Luminous/Phantom nearly as much, but the market says I'm in the minority there.
The Dato was a bit of sleeper for me, I’m not sure I was sold on it initially. Others in the series were more interesting I thought. But the more I see it the more I like it.
