Stephane,
When I asked TTK about this he said it was from the same source as MBW's but said they may have sourced the parts or most of the watch from another manufacturer. This is why I refer to it as "supposed" MBW. It seems Eurotimez 1655 "supposed" MBW is different than the one I purchased as Polexpete mentioned.
The case is still a good base though, I did not want to deal with the lug holes when I had it. I have to say my 1655 was by far one of my most anticipated projects too especially knowing the Omega hands could be fitted to the mvmt.
Keep us posted on the progress my friend!
