Older version of the flieger chrono very nice but smaller watch. Should have silver rings round the outer edge of the subdials but still very nice and not far from the gen. If silix still has it then at that price it will be worth it but be ready for a movement service as it will have sat on the shelf for a while.
Well the thing is things do go missing all the time in the post it is a bit of a hazard of the rep game, and infact any game where a lot of things move through the post, when this has happend to me generaly i am weilling to split the difference and both parys take a loss.
I would recomend the MK XVI with the asian 2892 copy with Antimag shielding.
It is a great little watch out of the box and a perfect starter to add straps to or a bit of modding like lume or add an ETA date wheel
The only start point i would use for a GWSD is an MBW, as has been said above any other you would regret later one the more you learnt about building GW
I would sugest an mbw also you can do the mods slowly in time and spread the cost but you will end up with something worth the sum of its parts if not a bit more in the end
