We may be hunting the same great white whale soon, my friend. ;-)
I agree, that the limited production period might make this more attractive to a collector. Who knows?
You are right, however, I am not sure how the 86180 would affect my watch rotation particilary with respect to the 1921 and the 1955. The 1955 has really emerged for me as THE perfect time-only dress watch. Honestly, I just cannot imagine finding another that will prove superior. So, in some ways I am using the lack of a white metal watch to try to justify another simple time-only piece. Yes, I can rationalize my way to another VC like nobody's business. A friend of mine and I were discussing our addiction to simple watches, and he mused that we seemed destined to end up with 50 time-only pieces. LOL.
And by the way, Walid, I don't recall seeing any photos of your Traditionelle...now would be a good time. ;-)
Best,
