Little known and unsung hero Klaus Jakob rescues old hand assembled calibres from dusty corners of Switzerland like the Venus 175, Valjoux 23 and Unitas 6300 and puts them in classic styled cases from SUG (case makers for Sinn). Instead of a Patek 5296, you could always save up for one of these instead from his brand Jacques Etoile.
Or if you like the look of a vintage Vacheron chrono or PP 5070, but haven't got the wedge, try finding one of these. Preferably with an updated Venus 175 column wheel movement. (If you're desperate, there's another cheaper one with a Valjoux 7750 - euwwww. I'll draw the line there.)
And to top it off, 100m W.R. I like this guy!
