I`m glad to show you my latest proyect: a 1665 comex with the famous 1665 case from Vietnam. The watch shows has:
+ 1665 vietnam case with "standard" DRSD caseback plus a comex caseback
+ 1665 comex dial vietnamese too
+ 702 gen tube + crown
+ gen tritium insert fadded
+ rolex 1570 movement with fist batch of silver datewheel (more "white" and bold than moderns)
+ gen 93150+580 bracelet
For those who think about the worth of that cases (considering they are f**ing more expensive than MBW cases) my thoughts are:
+ Case is 100% accurate, but the bezel correspond to post-1974 period (is slightly tinner than previous)
+ Crown and tube matches perfectly with the case, just like the real deal
IMHO, that crown make a big difference...
+ the engravings inside the lugs are very well done, close to gens as well as the inner writing in the caseback:
+ the dial is similar to MBW but with a important difference for me: one of the problems when you use 1570 movement on MBW dials is the size of the date window, in MBW dials the window is smaller (0,2mm or so) than gen, that makes that some days (ie 31 ir 10) seems very close to the borders and that thing never occurs int the gen. This vietman dials has the correct size as you could see:
Finally some pics comparing my "ultra-mod" MBW case (modded by repaustria and me) with my new viet case (on top in each serie):
Hope you like it
